How about some overclocking results guys ?

I am using the latest version of MSI Afterburner (2.3.0) I am reaching a stable clock ( until now ) ot +135Mhz Core and +1000Mhz !!! Memory clock. Interesting is that my performance in let say Furmark almost doubles with those overclock values. I guess they will go even higher if Afterburner had more overclock room.

While overclocked i am not getting hotter than 72 Degrees in Synthetics and about 65 Degrees in real gaming.

What about yours ?

I overclocked mine same as yours, saw a good increase in fps in games and temps only went from 60c to 65c in gaming
How far is it safe to push it?

Hi.

is core now 735 and memory 2400 with both of you??

Yes, +135/+1000 (735/2400) is a very safe overclock.

Done, I want more. GPU is definitely pushing more but I cant get MSI Afterburner giving me more than that +135

I have try this config file editing aproved that EULA but still cant get more same thing evga premicion x...

someone has pushed 670mx GPU to 790 I want to try same ;) now I get X1569 on 3dmark11

For 790 overclock use Nvidia Inspector utility.

You need to use the following parameter in cmd:

nvidiaInspector.exe -setVoltageOffset:0,0,0 -setGpuClock:0,2,790 -setMemoryClock:0,2,1400 -forcepstate:0,0

For going back to default state of your graphic card:

nvidiaInspector.exe -setVoltageOffset:0,0,0 -setGpuClock:0,2,135 -setMemoryClock:0,2,1400 -forcepstate:0,16

Instead of cmd window you can use Total Commander utility for easier navigation to the folder where you have the Nvidia Inspector installed.

DO not touch the voltage. Leave it 0.

anyone....
what is max clock I can push 670mx??? anyone with new results... I am using 2.3.1 MSI afterburner, cant get it more than +135 and +1000... when using GPU-Z while playing FC3 clock is @ 736 and mem @1199, although MSI says different, is there difference in measuring units between the two or...?
I do not need it actually OC'ed as all of the games I play runs perfectly fine except FC3 that I explained why on other thread... I just want to see what is the limit for upcoming games.... I can also see that 660M has way more higher clocks 1350/3300.... why is this - should not 670MX be faster? If I knew this I would have gone for VW version of g75... our max clock seems to be from gokica 790mhz!!:confused:

Clocks on 660m are higher but 670mx is more powerful GPU so even with lower clocks beats the 660m.

MSI afterburner and EVGA precision are limited by the bios and the drivers and no matter what you do they will always show +135/+2000 as a limit.

Only nVidia Inspector allows fixed voltage and higher clocks within the limits of the voltage. Owner of GTX 670MX 1.5GB (MSI laptop) reached 825/2400 which is the highest clock that I have seen on this card with default voltage (310.90 drivers). nVidia Inspector was used. I can not go higher than 2400 on the memory and more than 770 on the GPU with 0.925V on my GTX 670MX.

i got this error while i opening nvidia inspector.(System.DivideByZeroException: Attempted to divide by zero.) how can i open this program ?

A brief tutorial on Nvidia Inspector's command line parameters (with Total Commander utility):

1. Download Total Commander.
2. Install and run (press key 1, 2 or 3 at startup as required by the shareware version of the software)

The program will run and you will see a window which looks like this:

http://img715.imageshack.us/img715/7386/screenhunter15red2.jpg

Basically you see two windows for file management. In one of the windows above (left in the example) navigate with your keyboard or mouse to the folder where you have Nvidia Inspector installed. Once nvidiainspector.exe file is visible in the Total Commander window add the following parameters in the bottom line (marked with red square in the picture above):

For 750MHz overclock on the GPU of GTX 670MX:

nvidiaInspector.exe -setVoltageOffset:0,0,0 -setGpuClock:0,2,750 -setMemoryClock:0,2,1400 -forcepstate:0,0
and press enter.

For 760MHz overclock on the GPU of GTX 670MX:

nvidiaInspector.exe -setVoltageOffset:0,0,0 -setGpuClock:0,2,760 -setMemoryClock:0,2,1400 -forcepstate:0,0
press enter.

For going back to default state of your graphic card:

nvidiaInspector.exe -setVoltageOffset:0,0,0 -setGpuClock:0,2,135 -setMemoryClock:0,2,1400 -forcepstate:0,16
press enter.

During the process open EVGA precision in a separate window on your desktop and in it follow the frequency and the temperature. Please note that the voltage will be fixed and maximum while you are overclocking.
Play with the parameters as you wish but do not exceed the numbers.

Please note that the above values are valid for GTX 670MX. If you have different card in your computer modify the frequency values upon need. Do not touch the voltage in the parameters. Leave the value at 0.

So you do not need to run the Nvidia inspector by double clicking. Just enter the command parameters while Total commander has nvidiainspector.exe folder open.

If you have more questions please let me know.

If you want to use the program by double clicking and changing the values in it than here is brief info:

For changing the memory frequency in the nvidia inspector just move both sliders equally:

http://img818.imageshack.us/img818/8477/screenhunter13red1.jpg

If you want to increase the memory limit just press "unlock max" in the upper right corner. Than move shader clock and memory clock sliders both to 3000 (or any other value) for example. After both are pointing at 3000 (i.e. both same value) press "Apply Clocks & Voltage" at the bottom right corner. (I am sorry for the Asian language example).

As you can see the option for raising the GPU frequency in Nvidia inspector is dimmed in my case. I can only play with the GPU frequency via the command line parameters or via EVGA precision. I do not know why is like this.

These options work with my GTX 670MX.

In case you see a message popping up like "DivideByZeroException" or similar once you run Nvidia inspector try and use version 1.91 instead of the latest build.

Do not forget to monitor the changes in frequency and temperature in EVGA precision or MSI afterburner.

I hope this helps.

BTW the link to nVidia Inspector 1.91 can be found at the bottom of the Nvidia Inspector's home site blog. Posted by a Chinese member.

From what I understand that is a common error with a certain BIOS version. See if you can upgrade or downgrade BIOS and see if that helps.

As long as your not forcing pstates your good. Heck you can force them and still be fine the system will just run warmer. Every Kepler I have I ran over 1200mhz for a while now and my Sager with 2 GTX 680m's keeps them forced to 1300 the whole time. As long as your temps are good don't worry about it.


Side note here is a Cinbench run on my GTX 670MX. Not a max clock run and it was done on a out of the box G75VX with all the bloat. Not to bad i'll do some Max clock runs this weekend right now im just taking it slow and testing the system out.

How can you have 1000+ at memory? I use Afterburner, How does it look for you in there now with the overclock ? 755mhz on core clock ,but what on memory? My memory slider only go to 1950.. and when i put core to over 720mhz i get black artifacts when gaming. Any help?

Nvidia inspector. You force a pstate. and this is the command.

nvidiaInspector.exe -setVoltageOffset:0,0,0 -setGpuClock:0,2,@@@ -setMemoryClock:0,2,#### -forcepstate:0,0

@@@ is the core clock you want to oc to
#### is the memory clock you want to oc to.

Nice results guys! I have the Asus G55vw and I am perfectly stable with +135/+500 (1085mhz GPU Clock/ 5500mhz Mem Clock. My temps never go above 70c ever. I am using Asus GPU Tweak. I wonder why the base mhz rating on the 660m is so much higher than the 670mx? 950mhz was my stock gpu clock.

Since we can't "normally" modify the voltage, you can leave that argument out and shorten it to:

nvidiaInspector.exe -setGpuClock:0,2,@@@@ -setMemoryClock:0,2,#### -forcepstate:0,0

@@@@ is the core clock you want to OC to
#### is the memory clock you want to OC to, this should be input as calculated GDDR clock (2500 for stock clocks, or rather 1250x2), programs such as GPU-Z give you the base memory clock (1250 for stock clocks)

Guys,

Since I've never really gone in for overclocking (but I want to take the plunge now), which of the following utilities would you recommend as the best one for overclocking the GTX670MX:

- MSI Afterburner - I see it's the forum's favourite:
- EVGA Precision;
- Nvidia Inspector - I'm inclining towards this one but I'm still not sure because it's not an official Nvidia release to my knowledge;
- ASUS GPU Tweak - this one sounds good but I don't see many of you using it.

Besides, can I monitor the GPU's temperatures using any of these utilities and is there any risk involved - I mean damaging the graphics card or something else.

HI Shady,

Go for MSI After burner ...

I have a 670mx and able to overclock to +135 and + 1000

It allows you to have a monitor for the GPU temp in game and you can also customize what you want to see. Easy to use, and very quick so i would say go for that!

No risk involved as on our Kepler cards we cant overclock any higher then that! ... It is VERY SAFE and temps wont really go over 65 degrees.

So here is a quick run on the VX I got here. This clock is 100% stable and with the temps will be the daily driver clocks.

I still haven't maxed it out i'll do that this weekend and do a bunch of bench's but i'm expecting to match the lower end of the GTX 680m range. And I got a volt modded bios ready to go for this card so im expecting my final max clock to be in the range of 1200-1250 on the core.

Here is a quick little 3Dmark 11 Run at 5173

Edit.

3DMark vantage i'm breaking 20k without a volt mod so I should hit about 23-24k running my modded bios. Should hit about 5300ish in 3DMark 11. Lets see with a volt mod if I can get the core to my 1200mhz goal. Its nice to see a $1250 laptop nipping at the heals of a stock clocks GTX 680m

Ya 670mx is spec'ed at a lower clock than the 660m... but the 670mx is "faster" overall because of more cores, etc.

He won't. You do realize it's a hardcore mod and not some "totally safe" mod like "XXX overvolt mod, it works!!!" threads you see around that give such a small bump of voltage that it normally wouldn't matter (0.005v), the NVIDIA Inspector/MSI Afterburner/EVGA Precision stuff we talk about here or much of what you see on other forums, right? His modded BIOS has the potential to kill not only our NB's, but his own. He's just hardcore and crazy enough to try hitting those upper tier numbers and I'm guessing has the disposable income to make this type of hobby worthwhile and not sting as much as it would most of us.

Overvolting is 100% safe because of what the GPU is speced for. Now its only safe if you keep your temps under control and do not push the voltage to high. Voltage is what kills not the clock and we know what Kepler can take and the max it can. Also voltage bumps = huge jumps in temps. As with the VW my modded bios will never be made public as this is to advanced for 99% of the people here and will just cause problems and this voids the warranty. Messing with the bios can brick the card and your warranty will not cover it. So Dont ask it won't get made public for those reasons.

Bone stock. With my modded bios and the voltage bumped up i can hit 1330 on the core stable anything higher i get driver crashes. So im going to test other drivers see if i can get a set that wont crash so i can start to see them atrafacts and the reboots to let me know im overclocking.


When im done i'll be making a big post like i did for the GTX 660m and post the highest clocks and all those benchmarks.

A GTX 680m is still faster but im on the bumper of it, what is not bad for a $1250 system considering a GTX 680m is $700 alone.

1330MHz can only be a dream with air cooled GTX 670MX. I never read your 660m post but I am looking forward to the post on this OC.

I am curious what are you using for cooling and also which software did get you to 803MHz with stock voltage?

Well my GTX 660m was pulling 1300 without a volt mod and was stable to 1350. With a volt mod i expect nothing short of 1200 on the core of a GTX 670mx. With close to the same temps i was getting on the GTX 660m. Load at the max clock i was benching i was only seeing 85c on it.

gokica
03-03-2013, 12:02 PM
660 is not the same with 670MX.

I think that with the laptop cooler you will reach 85 C at load once you are at 900-950 with some voltage increase.

My personal opinion is that the power section of the card can not withstand voltage of huge proportions to get you to the speed of 1200MHz with this card.

But good luck with it.

Hi everyone,

It is my current understanding that clocking the 670mx gpu past +135 +1000 may be undervolting the GPU on stock voltage.

here is my logic and reasoning, I have Bench marked the following

core ,720 memory, 2300
core, 730 memory, 2400
core, 736 memory, 2488
core, 740 memory, 2500
core, 745, memory, 2515

with these results core 736, memory 2488 obtained the best results in 3D mark,
http://rog.asus.com/forum/showthread.php?28872-The-New-3DMark-Post-Your-ROG-Notebook-Scores-Here!&p=246513&viewfull=1#post246513

the higher core/mem clocks did not increase benchmark scores, however an increase of gpu temps were noted.
what this tells me is that the GPU has reached its voltage limit and is actually slightly undervolting causing slight instability at stock voltage but not necessarily its highest processing potential.

Think of undervolting like driving a car at its rev limiter. The car accelerates to the limiter then decelerates, then accelerates, to the limiter then decelerates again in rapid concession. Ideally a car that reaches the point right before the rev limiter will be faster because it can maintain a constant speed.

I presume the above is whats happening with either the memory or core latency at specs higher than suggested.

I figure the sweet spot for this gpu at stock voltage is core 750 memory 2200

basically what I am doing to keep voltage constant without undervolting is for every 10mhz core I add I remove 100mhz memory I haven't done the calculations but in theory this should keep the overall voltage in line with the stock maximum voltage.

I am still in the experimentation stage with stock voltage and am already very pleased with this GPU's processing capacity.


Another thing I want to point out

The 660m and 670mx consist of very different architecture.

A few main points being the
Core Difference 960 vs 384
memory width difference 192bits vs 128bits
TDP are the same *Edit.
These three go hand in hand with the output of the processor, the TDP states the amount of heat the processor can take as a result of voltage/current consumption-dissipation as you can see the inherent design of the 670mx is more efficient however less suitable for being a voltage crammer.

I look at GPU's like bridges,.

the core's are the number of lanes on the bridge, the memory width is the distance from the start of the bridge to the end and the TDP would be the maximum amount of weight the bridge could hold at one point without collapsing. Then the memory and core clock speed would be considered the speed at which the cars crossing the bridge would be moving

We see right off the back that the 670mx has more lanes and a longer bridge therefore it can sustain a larger volume of cars in width and length however even though this is true, the 660m's bridge can sustain more weight (voltage) than the 670mx, which allows it to sustain crazy 3100mhz memory clocks, and also outrageous core clocks. the 670mx was not built for that plain and simple, its built for efficiency with moderate speed. Im sure no one will get too far with voltage modding this GPU because Im already hitting 65c... 80c is what I consider dangerous for a 65w gpu so a 45w gpu is right at its threshold at about 70c...

Good luck everyone on your overclocking endeavors, but be smart and use logic please!

gokica
03-31-2013, 02:08 PM
I think that there is a lot to be revised in this logic.

Think of the 670MX as undervolted and underclocked GTX 660. It has the same memory chips and the same GPU.

What is different is the board layout. Since 670MX was designed to run in a laptop where the cooling options are slightly different and where the PSU is also a limiting factor the card was designed with twice less mosfets for the core (weaker power section).

But the memory power section is the same. So basically running the memory at 1400MHz (2800MHz in MSI afterburner) is quite safe and will actually bring the card to its full potential. This is impossible on most G75VXs since the memory voltage is lower comparing to the desktop variant (the GTX 660).

As for the GPU, the true potential is unlocked when clocked somewhere above 900MHz (920-950) at stock voltage (0.925v). The reason why bios and drivers limits are set +135/+1000 is due to the following:

1. Nvidia specifications are 75W card. This means that higher clocks will bring it to the 100-125W territory.
2. Nvidia will face sales imbalance since 670MX/675MX clocked higher is endangering the position of the lot more expensive 680m.

EDIT: Try running the memory at +1000 (or the max that you can reach) in all different scenarios and you will always have better results than the ratios that you elaborated. What will be questionable is the benefit of running the memory with speeds above 1500MHz (3000 in MSI afterburner) which can only be done with hardware "pencil" mode. And finally +135/+1000 is not undervolting the GPU. It gets undervolted once the temperature overcomes the 60C limit. It will downvoltage for -0.025v.

ManOfBusiness
03-31-2013, 03:33 PM
Also it would be a good point to note the 670mx will meet it'd threshold faster than a 660m because it is overall a beefier GPU restricted under the same voltage.

Edit: Ok I just ran 736 core with 2600 clock and got artifacts but before I did these were the scores

The GPU is at its limit at stock voltage at 736 sub 2600

now you may be able to get better results increasing core clock and decreasing ram clock, but im sure the scores will be marginal.

I don't plan to modify voltage, I've had bad experiences in the past. Good luck to all who do.

Just a hint. The memory voltage and the GPU voltage on your card are independent. What affects the OC in the equation is the temperature.

Your GPU is far from the limit with the 0.925v. Your memory limit is at about 1300 (2600 in MSI afterburner).

Here is something from my laptop:

EDIT please do not ask me for OC mods since ASUS ROG forum does not support OCing your laptop.

Also do not use Nvidia inspector for OCing your 670MX because it does not work as expected and will give you wrong ideas about the OC potential. I wrote a tutorial on other forums a while ago but it is not to be used. I found out later that 670MX has lot more potential and Nvidia inspector is just limiting it substantially.

If what you say is true, and core voltage and memory voltage act independently, then why is your memory clock so low?
I know there are other means to "over" overclock the 670mx however I don't plan to go over 850 core on this gpu.

There is already an unlocked bios for this notebook so I presume that is what you're using to clcok.

I'd be interested in seeing some benchmark scores and temp scores if you have them. If I had to take a guess your scores with that low a mem clock are not much higher than mine but with higher temps.

we all know the core is the main aspect that produces heat, the memory heat increase is miniscule in comparison.

Thank you for sharing. I've also been researching the GTX 660m and I see what you are saying there.

Hes running the memory at 2600mhz Vs the stock 2200mhz

I don't know where you people are getting that the core and memory voltage is shared.

This is my stable run at stock volts. Keep in mind with the volt mod i have gotten this to over 1500 on the core.

http://www.techpowerup.com/gpuz/fb7cg/



Also i would like to point out that you said the architecture is way diff between the GTX 660m and GTX 670MX and you could not be any more wrong unless you called the GK104 a taco. They are both Kepler. Kepler is the architecture. And your main points you point out are not architecture diff. they are core diff between two GPU's. The cores are diff. the architecture is the same.

Hello guys,

I have a G75VX, and I have overclocked my GPU with MSI Afterburner (+135/+1000). With these settings, I sometimes get 75 degrees while gaming. Is there a problem?

If not, is it safe?

If it is safe, can I push further? Thanks in advance!

gokica
04-04-2013, 09:51 PM
I believe that for the moment you should not push much further.

If the ambient temperature is normal (not above 22-23C) than it would be wise to repaste the GPU. This is in case you have a desire to OC further or if you want to receive lower (well normal) temperatures. If not than you are just fine where you are right now.

mertbsn
04-06-2013, 08:28 PM
Would repasting work for sure? I mean the laptop is kinda new, it has only been a month and a half since i've bought it. I mean, don't they put enough paste while producing? :D

I'm sorry, I'm new to this stuff.

Thanks

gokica
04-06-2013, 11:47 PM
It seems like some units have bad pasting job on them. It could be the case with yours. As I said if the ambient temperature in your room is normal and the GPU OCed to +135/+1000 goes to 75C maybe you could get to better cooling results if you re-paste. My GPU temps never go above 60C (ambient 20-22C) at that frequency.

To overclock try using nvidia inspector its a great tool and is simple

gokica
04-07-2013, 09:57 AM
Nvidia inspector does not work properly with GTX 670MX. It can get the card above the Vbios limits but not even close to its full potential and there is always a chance of drivers crashing when this utility is being used.

MSI Afterburner and EVGA Precision offer the same OC results although I prefer EVGA due to the fact that it provides voltage monitoring and K-Boost (4.0.0) which can constantly lock the voltage / core clock at their max for highest results (this is also possible with Nvidia inspector).

mertbsn
04-07-2013, 10:00 AM
My ambient temperature is pretty similar to yours, and I think there might be an issue if yours don't go above 60C. I will try repasting for sure. Thanks for your help, gokica :)

Edit: Just checked it out and saw that my idle temp is 50C.

I am sorry but laptop OCing is not supported on this forum and therefore I can not say much but just show what is possible.

It is not as simple as running an OC utility.

btw, is 78c safe ? how long should i make this running on this temperature? suggest anyone?

At those clocks my 670mx reaches 72C (ambient 21-22C) after 3 minutes of Kombustor test. On a long run it would be probably 75C max. If your ambient is little bit warmer the temps on your card would be the same as mine which I consider normal.

Kombustor temps are not to be considered as usual GPU temps because games do not make the same load on the card.

75C is the recommended max temp for your card although nothing will happen if you take it few degrees further. Even 85C will not burn your building to the ground.

Measure the temps while gaming and this is how you will be able to see the max temperature that your card can reach. Crysis 1 and the Unigine heaven benchmark will show pretty much the max temps while gaming. I assume that OCed to +135/ +1000 your max temps should hover around 65C more or less.

I overclocked mine same as yours, saw a good increase in fps in games and temps only went from 60c to 65c in gaming
How far is it safe to push it?

How the hell do you have 60c ? what kind of game do you play? My card non-overclocked reaches 67...


paste is bad on mine I guess

Why worry about temps from kombustor? What is your real
World daily temps overclocked? I only OC mine hen playing BF3.
I OC it to the max afterburner will allow an play bf3 for 8-10 hours straight and my temps don't get about 65.. Unless your using your laptop only for benchmarking and not actual use...

adamsyes
05-19-2013, 01:06 AM
i play BF3 for about 3-4 hours just to test the temps condition. it hits 64 when the room temps are reasonable (19-23c) although, when i OC it hits 72 in 10 mins so easily. same room temps too. (i usually get 67c non OC when the room is kinda hot which makes sense but kinda big temp increase imo)

i use Nvidia inspector monitor and nvidia observer gadget.

I mean, we can all agree some units are very well pasted and some aren't. not complaining but this kinda forces guys who are temp freaks to re-paste and ignore the whole warranty criteria. also i assume the 670mx heats more compared to a 670m right? i

tgamer007
05-21-2013, 12:28 PM
The 670MX heats less than the 670m because of its Kepler infrastructure. 670m's infarstructure is fermi, which generates more heat though any program or task that involves using that said card. 670MX + G75VX great cooling system = an overclocker's dream. Right now I am using a modified BIOS/vBIOS that unlocks the CORE and MEMORY CLOCKS. Sitting at 900/1100 and temps are stable between 70-75c...

I read everything on this forum and I am calling bull on the fact that people are overclocking +1000/+135 without seeing the Temps go above 72 Celsius. I have tried several laptops and all of them the g75vx and when those over clocks are put in I am getting Temps in the high 70's to low 80's playing bf3. Regardless of that I have read nothing on any of these forums that discuss a safe temperature for the 670mx. If the g75 I am running stays at 80 degrees Celsius is that to hot or no? That temperature is using a cooling pad and the ambient air temperature is around 70 degrees. If anyone who posted the low 70 temperatures could please respond directly to how they keep the card that cool would be great. I have a feeling the only way I would be able to see low 70 Temps would be to use my laptop in a freezer.

The ones saying their temps are at the low 70 C degrees might be because they have repasted it :)
Plus I know dreamonic went balls to the walls to keep his laptop cooler by modding an direct air intake mod to the case by the fans
Which looks absulutely badass might I add :)

Or generally their thermalpaste was done better :)

Keep the temps below 80C but somewhere Asus reps says it's acceptable temps
But remember heat is never good for electronics... Just look at the MacBooks from 2011 their GPU malfunctions after 2-3 years because it has 80C plus on the GPU (trust me I had one before I got this G75VW)

My GPU temps are actually in the low 60's. I don't think most of my games are very good for benching/stress testing so I've mainly used synthetic benchmarks. With 3Dmark (2013) and Unigine Heaven (max settings), I peaked at 61C. I ran Unigine Valley for a little while last night and the temps capped out at 63C, occasionally dropping back down to 62 or 61 during some parts. MSI Afterburner logged my max temp as 64C, but it must have only been for an instant as I don't remember seeing it in Valley's built-in GPU temperature display. I also kept track of my temp while playing Starcraft 2 a while back, and I think the max was about 62C.

All these temps are with +135/+1000 core/memory OC with MSI Afterburner. I don't have any modifications and I have stock paste (got the laptop about 4 months ago). My living room (where I keep my laptop) tends to be a little cool during the winter, so I suppose my temps might be a bit higher if I were to run these benchmarks in the summer.

How about some overclocking results guys ?

I am using the latest version of MSI Afterburner (2.3.0) I am reaching a stable clock ( until now ) ot +135Mhz Core and +1000Mhz !!! Memory clock. Interesting is that my performance in let say Furmark almost doubles with those overclock values. I guess they will go even higher if Afterburner had more overclock room.

While overclocked i am not getting hotter than 72 Degrees in Synthetics and about 65 Degrees in real gaming.

What about yours ?

I have a question, why is it everyone can overclock their gpu, yet even when i run stock my temps go into the high 70's playing bf4 and if I
overclock playing bf4 my temps will go to a max of 83? I have tried every option and my laptop is less then a year old and I do not feel like
repasting the gpu. I find it hard to believe that all these other laptops run so much cooler then mine. Please tell me how you keep your temps so low.

I take off the bottom panel for both GPU and CPU. Lift up the notebook to get the air flow under ( this will help a lot my temps drop around 5c - 10c. I'm using CM U3 cooling pad temps drop 3c - 5c.

This goes out to everyone... how does everyone keep their gpu from hiting high temps?? The cpu is not
a problem, the highest that ever gets is 64 degrees Celsius. My gpu on the other hand like I said goes up to 83 degrees Celsius when playing bf4. My fans are clean and the laptop is on a hard surface.. I can also say for sure that the fan is spinning at the RPM it is rated for which I believe is somewhere around 3,200 rpm.
