Hello,

I was wondering what temperatures everyone has been having on their G750's
Mine have seemed to have increased from when I first got it and I wanted to do a comparison with others.

CPU:
Idle: 40-45C
Web browsing/streaming: 40-48C

For heavy gaming it really depends on what game i'm playing, BF4 stays around 67-73C

GPU:
Heavy Gaming: Usually 65C, however with the new driver, it hit 69C today.

What temperatures are you having?

Hi Torpedo499

Is your power plan set to high performance or balanced? mine is set to high performance and my idle cpu temp is 63C... if i change it to balanced it shows 53c...in games like bf4 i've seen it around 75-80.. which when it goes over 70c it starts to throttle and i am not sure why.. do you know your core voltage for cpu?

My gpu temps are aroumd 75-85c because i am overclocked.

Torpedo dont worry, your temps are even lower than what they should be so you're alright.

kingkaan, you seem to have a faulty unit, if your CPU is kicking in thermal throttling when temp goes above 70c you should RMA immediately!
g750's are able to hold off thermal throttling even when CPU temps reaches 90's. And about your GPU, even with overclock you should not be going anywhere above 70-75. My GPU in 750JW is overclocked as well but it barely reaches 65c on heavy games. My suggestion for you is to RMA. One thing is sure - CPU should not throttle during normal usage - games/browsing/movies/etc.

Hi Torpedo,

My idle temps when doing nothing at all fiddles around 38-45c for CPU and around 40c for GPU. When playing heavy games CPU might get up to 80c but nowhere higher, and thermal throttling isn't kicking in which shows that temps are just fine. A guy from Asus support told me that g750JW's normal CPU temps on heavy load are around 83c so Im alright. GPU temps doesn't get higher than 65c during long sessions of heavy gaming or whatever. And just to make you feel even more confident about your temps, if thermal throttling is not turning on during normal usage you are more than fine, it means that your cooling system is able to control the heat, as soon as cooling system can't hold off the heat much longer CPU turns on thermal throttling which then cuts down the maximum CPU frequency and temps starts lowering. However I suppose this will never be the case for you since your temps are perfect. By the way I have undervolted my CPU so my temps are lower than what they were with the stock settings. You can do that too with Intel XTU which is official Intel software and not from a 3rd party. You can also overclock your CPU and GPU, your CPU should handle it just fine, GPU as well. If you just recently bought you ROG don't be afraid of fiddling around with overclocking because once you get it right you can enjoy boosted performance for the long time to come. :)

By the way which one G750 do you have?

Hmm 83C seems very high for the "best cooling on the market"

I'm using a G750JW.

It is indeed best cooling on the market, can you imagine if you had all that hardware under some HP or DELL laptop? It would go into 90-100c temps in seconds lol

If I were to OC my JW, I might see 60-70 for CPU, 60-75 for GPU playing any game.

If you're not OC'ing, those temps are too high.

noone, you are seeing those low temperatures because you aren't pushing the CPU enough.

On my JW/JX I pushed the CPU temps up into the high 80's and even the low 90's depending on the ambient temperature, and the test I was running. The JW and JX CPU temps on the same test runs were essentially identical.

Here are my results on a JX, for a 5 minutes Stress Run in XTU, with a HWinfo64 monitoring session next to it. Without tuning the max temp was 87c, and with OC + reducing CPU voltage with XTU it was 88c

I did a Snippet image capture right at the end of the run, Clicked New a couple of seconds before it ended to grab the image.

The first run with a -60mV voltage offset to reduce heat, with the multipliers set to max OC, 36x/35x/34x/34x 36x:

35814

This is the same test on stock settings

kingkaan, when are you going to RMA and get that thermal throttling problem fixed?

I recall you mentioning this months ago... how much warranty time do you have left?

You shouldn't be thermal throttling at all. So if you are, it is a bug that needs to get fixed :)

Look at the runs above for the XTU stress test, and the HWinfo64 readings, no thermal throttling.

Thank you very much.

I really want to keep my CPU under 70C when intense gaming, and I don't plan on Overclocking my CPU because I think it really offers great
performance, when my warranty is over, I probably will OC my GPU as it is the main cause of a lower FPS in games.

Ok, so I was running the XTU stuff and I was getting weird numbers. First, I ran the stress test for around 10 minutes and it reported back that the CPU got up to 87-88C. Then, I went on a little later and ran the Prime95 Benchmark included in the software, got 711 marks, and racked up a max temp of 90C. Is something wrong with the laptop? During regular gaming and stuff like that, I'm don't really ever go above 70-75C (GPU usually gets to around 70C too). I got it from Prostar and they did some customization work on it and I just wanted to know if it is too hot or something. Thanks!

CPU can usually go up to 99C though 90C is the recommended MAX! So your fine but 90 C is a little hot though , but not getting damaged.

Art3mis777, those numbers are normal. Those stress tests, especially prime95 are designed to push the CPU to the maximum to weed out power supply and cooling problems, normal usage will be much less.

You can undervolt the CPU using XTU, set the CPU/cache voltage offset to -25mV - -125mV depending on your particular CPU, and that reduces the heat generated a bit keeping it cooler and reducing the fan run times.

Using the Balanced Power plan will allow the CPU to downclock during idle times, reducing heat too. I only use the High Performance plan when trying to get the best score in benchmarks, normally I run in Balanced.

I also uninstall the Power4Gear app as it forces it's own plans into play when I want to keep my own Windows Power plan selection - the Power4Gear plans are the same as the Windows plan other than the automatic changing - which I don't want.

These CPU's have thermal throttling power protection that will kick in as the CPU gets close to 100c, but you shouldn't see that ever happen - the Asus cooling is excellent and ramps up the fan enough to keep from going in to thermal throttling. The JW/JX fan curves are the best - in regards to quiet operation - they let the temps get high before kicking in the noisy fan speeds.

You can watch for thermal throttling with the XTU monitor, but I like the HWinfo64 Sensors monitoring where it shows Current, Max, Min so you can look away and still see if thermal throttling happened while the HWinfo64 Sensor was running.

To get this view, when you start HWinfo64, check the "Sensors Only" box before continuing for that run.

Thanks a lot! I've been worried and this gives me solace. I bought this thing less than 2 weeks ago and I love everything about it (customized it with a blu-ray drive) and I love how it plays Warthunder at beyond movie settings at 40 FPS and Planetside 2 on high nice and smooth. I plan on using this thing for 3D CAD, rendering, and Star Citizen/high-end gaming. Oh yeah, do you guys think that the G750 will be able to play Star Citizen? I have the JS model with the 870M and 16gb of RAM (3gb of DDR5)? I was wondering about that.

Art3mis777, I haven't had a chance to play with one of the new G750 JM/JS/JZ with Optimus enabled, but from reports they do run hotter when using the Intel GPU - as it is on the CPU die - so enabling and using those GPU portions of the CPU seems to generate a hotter average temperature than the JW/JX/JH for the same CPU tasks.

You could use the Nvidia / Intel GPU settings to force each app you use to only use the Nvidia GPU, that would reduce the Intel GPU heat generated on the CPU. It would be like disabling Hyperthreading on a desktop CPU to idle those circuits and stop the heat they are generating - which is a trick to allow higher clock rates on a desktop CPU by raising the heat ceiling of the CPU.

The Nvidia JZ 880m GPU base clock and max clock is higher than the 780m in the JH, and it generates more heat for the same tasks too, so Asus added a manual Boost Fan option for added cooling when you think it needs it - but that is only for the GPU (right side) cooler.

IDK anything about Star Citizen, how about you try it out and post some optimal settings and results when you run it! :)

alright, I'll make sure to post when it comes out and I get it (sometime in 2015 :D). Thanks a lot for the help though, it really took a load off my shoulders.

my idle core temp is around 53C when running on battery alone, and if i switch to ac and remove the battery the idle core temp spikes up to 70C even 80 without doing anything in background.
ps - my laptop is almost 3 years old and hasnt been serviced or cleaned even once.
please advise what can i do to lower the temperatures

Hello,
I own ROG G750jx for 4 years now and after years of use applications became more and more demanding to hardware. My G750 is still able to handle all the work I do with it but especially when hard gaming temperatures rised to:
- 98 deg C in CPU
- 77 deg C in GPU
I measured it with RealBench V2.43 and HWMonitor. My venting fans were running like hell when under heavy load.

So I decided it's time to do some major maintainance of my G750. I searched in Youtube for video how to disassemble G750 and I was able to disassemble it with ease more or less (you have to mark every step, part and screw to asure to assemble it back with ease).
Venting fans and cooling ribs were moderately stucked with dirt, so I cleaned them with a can of compressed gas cleaner.
I also took a chance to replace thermal compund on CPU and GPU (previous one wasn't in best condition). Just be aware if you choose to replace thermal compound on GPU, you have to place it not only on GPU chip but also on other components of graphic card (it looks like it's almost all filled with it) - if it's not overheating then leave it alone.

After assembling my G750 i did some same tests with RealBench and HWMonitor and it worked. I was able to lower max. temp:
- CPU - now max. 80 deg C
- GPU - now max. 60 deg C

I think I spared my G750 some more years of it's lifetime, so I strongly recomend to do some major maintanance after few years of use.
