I have had my laptop for 2 years now and have never had a problem with it even getting warm let alone hot. I just started having problems with my display drivers not responding and then recovering. I think I narrowed it down to unusualy warm air coming from the right fan vent on the back of the laptop ( left fan vent if you face the back of the pc ). I am not %100 positive this is the cause but It has never been this way until now. Is there any free fan rpm control I can download to extend the life of my slowly dying display adapter. I have a Rog G75 VX with win 7 ultimate 64 bit OS. this info or any other to help this problem would be nice please. I have looked through the search and have not found any results for this specific machine and fan speed control . Sorry if my question sounds too minute for anyone to answer I am new to this but very eager and willing to learn. Everyone has to start somewhere and there is only one way to learn. Thanx all in advance

It sounds to me like your GPU is overheating the fan can only help so much. Your fan will run full speed from about 70c.
I suggest you load Hwinfo64 run the sensor and you will see your CPU & GPU Loads Temps and Fan Speeds. With this information you might see that the pasting on your GPU is or has failed.

I don't know of any fan profile programs that will work on a G75VX

Ok Last night I tore my laptop down and gave it a thorough cleaning. I had installed speedfan b4 this and my fans were running at about 1800 rpm and all temps were over 100 deg fht including the gpu it was highest at 118 deg fht. After the cleaning the fan speeds were a little ove 2000 rpm and all temps had gone down just below 100 deg fht and the gpu is still hottest at 101 deg fht. I didn't even know what thermal paste was until you said that. From what I understand it connects the gpu/cpu to the copper thermal coupler and draws the heat out of them kind of like a radiator? Since air is a poor conductor of heat this paste insures the heat has a path to escape into the copper? Is this right or am I way off? So if it fails I need to repaste them right. Also the old paste does it need removed before I repaste?

And you are right if there are any fan profile programs for the G75VX I could not find them. Speed fan only gave me the rpm/load/temp but did not work in controlling the fans at all.

Also I wanted to say thank you for your reply. I am new to pc maintenance but I am eager to learn. I have the skills but lack the knowledge. I am a cnc rebuild tech so I am not a complete idiot like a lot of people try to treat individuals on these forums. Just saying I appreciate your time and thank you again.

I was told that anything over 100 deg fht is slowly cooking memory.Is this right and if so around where should all my temps be for this model? Also after reading about the thermal paste I read there are 3 main types witch would you recommend for the G75VX? Sorry so many questions just slowly learning. The day I quit learning is the day I give up.

Yes your temp are way to high and your fan speeds very slow? Under full CPU load mine run at 3800 RPM using burn in test my CPU never gets of 75C. The temps you stating your CPU and GPU would be Throttling to protect the hardware.
Repasting is not something to take lightly with notebooks. While a straight forward thing with desktops. It not impossible as many here in this forum have accomplished this. If mine goes bad I'll probably attempt it myself.
Most of the Custom dealers are repasting using IC diamond paste before you even get it from them. You might be able to get Asus to repaste or one of the custom dealers too? Shouldn't be too expensive for a shop that knows exactly what they are doing and have all the proper material and tools. I would search You Tube. There is one really great video on complete disassembly (https://www.youtube.com/watch?v=z9KHrJKInmA)

Ok Thanks for the link. I did look and found some vids of the VW models witch I assume are very similar. I don't have any custom dealers or shops anywhere close to where I live. From the vids I have seen I am fairly confident I should be able to manage the task. I do understand these parts are very delicate. I did find some formula 7 diamond paste at BestBuy. What points or advice about this process would you stress the most.

Follow the direction I'm unfamiliar with the brand you bought but should be all the same Pea size drop center of the CPU and GPU. Just be very careful not to break anything. I don't remember the other guy's that did this had any issues as long as they were very careful separate your screws and Identify them. Yea a VX would be pretty similar I think You Tube seems to have lots of video's you could always ask the author of some of them also you could PM any of the cl- ** or @asus demonic might remember he did some serious mods with his VW. I think that Asus uses thermal pads instead of paste so be sure to clean all that crap up. You could look back through this forum its been a while since I seen anyone talk about repasting. Most everyone has moved to the 750 or 751 you could also look around the 751 forum a lot to the guys there have just moved up from G75 Hmscott might put you on the right track.

Well I finally decided to go ahead and take this task on myself (Hopefully no regrets LOL). I will let you know how it goes. By your last post I assume you recommend the drop on then let the staggerd tightening of the heat sinks do the work of smoothing it out. Or should I attempt to smooth the paste out on the gpu and cpu myself before installing the heat sinks back on ? I have seen both methods done in vids. My only concern is if I don't smooth it out myself that it may still be too thick after the install. Well if I don't hear back from you before I start Ill just feel it out as I go. Trial and error works. I just really don't want to have to tear it back down again. I am a firm believer in the "if its worth doing at all , its worth doing right the first time.

I don't know what your manufacture recommends but IC Diamond specifically states not to spread it out but to use Pea size ball in the middle of he CPU GPU. they state that due to the viscosity of there product spreading can leave air pockets.

I just did a desktop with IC Diamond and did it just the same way this video did and my temps are in the 20c's idle

I did repast both my cpu and gpu with the antec formula7 nano diamond paste. It did drop the temp but barely. Everything went fairly smoothly I was surprised at how sloppy the old paste had been applied. If you can think of what else it might be I am all ears. I did find someone else with the exact same problem maybe they will have better luck finding the problem. Thanks again for your time.

Also I did use the drop method after seeing the paste was not very thick as I thought anything called paste would be (LOL) . I am confident I did everything right and did not get it to thick or not enough. I don't know where to go from here Other than the fact I don't feel like my fans are coming on as much as they should. At temps this high I would think the (SMART) program they run from would have them both full blast all the time. It even seems like my gpu fan (right if facing the screen) is not coming on everytime I attempt to run it. They both do work and have come on but I have never seen them over 2000 rpm or both run at the same time. I dont think the fans themselves are bad I think it might be a software problem but have no clue how to check or fix this. There is another member on here who had the same problem a couple months ago so I sent him a pm but have not heard back from him. He replaced both fans on his with no results so I don't want to waste money trying that.

I will again recommend you install Hwifo64 (http://www.hwinfo.com/download.php), run the sensor and report back what your CPU and GPU Loads Temps and Fan Speeds are. Asus doesn't use paste they use pads.
Well the fans are controlled but the Motherboard IE BIOS/UEFI as far as I know Asus does not allow fan control in any of their notebooks. So there is no software.
You say the paste you used was of thin consistency? The IC Diamond (http://innovationcooling.com/application.html)that I used is very thick and hard to get out of the syringe. Speed Fan I don't think accurately reads your fan speeds Hwinfo64 will and allow you to log your fan profile over a period of time. Your fans should Idle at around 800 and max out at around 3600 at least that's what the VW does. Check out the IC Diamond link. What you said about yours being "not very thick" I suspect that perhaps it has separated the carrier from the diamond compound and all you got between your CPU GPU and heat sinks is the carrier??

Ok sorry I did not note that I did take your advice and dwnld Hwifo64. The temps, fan rpm , etc. were about the same as speed fan but I did go ahead and get Hwinfo64 as per your suggestion. Witch using this has just confused my thoughts even more. The fans don't seem to follow any type of protocol all the time from what I have seen. They normally alternate at idle but not always. Once one shuts off the other comes on regardless of temp and there is never a huge difference in rpm they seem to stay close to 2000 rpm. I have seen them both on at idle once. Once under a load they still alternate regardless of temp but then both stay on at the same time more frequently still at the same rpm. Almost as if its a personality disorder instead of tech (lol). Yesterday after observing its strange behaviors it dropped temps and ran just fine without a problem. Today when I started it up the problems were back for a short time and now they are gone. At any rate my CPU fan when running is at 2017 rpm, load is 2.5%, and temp is 35 deg Celsius. The GPU fan when running rpm is 2007 rpm, load is 3%, and temp is at 36 deg Celsius. I listed temps in Celsius because more people seem to use this temp unit. I think these are normal readings except for the fans rpm. I guess I will have to see how it acts and post my readings when it starts acting up again? As for the paste being thin Its consistency reminds me of a thin tooth paste. The only reason I said that was from seeing other vids where the paste they used looked more putty like than paste. Also you said Asus does not use paste?? Does this mean I bought a refurbished laptop from best buy at a New pc price?? They sold it as new but there is no doubt it was pasted. I will try to keep a closer eye on the temps, loads and fan rpm today. Incase Maybee I am going crazy from not being able to pin point the problem and my minds playing horrible tricks on me with the fan rpm's . Thank you again

I don't know if you got a referb or not. lots of manufacture use pads there are consistent in thickness and more reliable in a factor line. So they work and hold up good. the ones that don't end up here. Your Idle temps look good. But if your temps go up and the fan only goes to 2000 RPM you would have a motherboard problems. I don't know what BB does with there notebooks. I do know if you buy from a custom dealer they repaste for you with IC Diamond. Best Buy usually puts in less RAM cheaper screens and cheaper slower hard drives.
Yes you can leave the Hwinfo64 Sensors running for quick look reference you can also set it to create a log file that you run over a period of time.

http://www.amazon.com/StarTech-com-Heatsink-Thermal-Pads-HSFPHASECM/dp/B0009B0K2I will give you a idea of what thermal pad are.
