G50 and Windows 7: GPU too hot when idle

Hi,

I installed Windows 7 and it's working fine.
However I do have a problem with my GPU temp. It often reaches 70°c when idle (or surfing on the internet) and consequently the fan blows which is very annoying.

I don't seem to have this problem on Vista (dualboot). Indeed the GPU frequencies rarely go over 168,75mhz and 337,50mhz for the core clock (ROP and Shader) and 100mhz for the memory clock (RivaTuner monitors temps).

On Seven it's like a rollercoaster. GPU power is often unleashed when I'm just doing basic stuff on windows.

I don't if it's normal. Currently my drivers are 186.81. I also tried 186.31 but it's the same.


Does anyone experience the same issue ? It seems like Powermizer is not restrictive enough (I'm mostly on power saving mode though).

Thanks for helping!

 

My Powermizer doesn't even work at all...

It appears that Windows 7 GPU drivers have some wonky power managemetn issues at the moment.

 

Asus Gaming laptops run very hot. It's been like this for 3 years. My C90S idles at 85C

 

ya same here my idle temps go up in windows 7, but for you 85 degrees at idle seem kinda overboard O.O. Imagine if you would play a game

 

I have my GPU downclocked manually and the G60Vx is running at 25C Idle (T9900) and 50C Idle (260 M GTX).

Once my notebook cooler & ICD7 comes, it will be going into the 10s and 40s....

 

I'm using Windows 7 on my G51, temps usually between 50-60C. However occasionally the fans wll turn off and the fans wont kick in until 60-70C (GPU temps always fluctuate for me! ). You can download the 'Powermizer Switch' if your GPU isn't downclocking, it has worked for me

 

Unless your ambient temp is lower than 10C you wont see that happening. Remember you using air to dissipate the heat thru a aluminim/copper heatsink, so if everything were super ideal and the transfer would be instant the lowest you could get is the same as the air cooling it, which would be your ambient temp at the lowest, and this is just unrealistic, so expect at least couple or more degrees higher than ambient temp.

 

Ok thanks for answering.
JCMS I know Asus gaming laptops run very hot (I've had a G1S, big mistake) but in Vista there's no problem, the frequencies remain downclocked so I guess it comes from Seven.

Anyway it's good to see I'm not the only one experiencing that. I just saw another thread mentionning the problem: http://forum.notebookreview.com/showthread.php?t=427958

 

my g50 idles at around 60 c in a semi hot room with the zalman cooler and the latest drivers from nvidia

 

I don't expect 10C hah... but 19s and 18s is realistic.
But I'm sure you can have lower than ambient temperatures. It may only be slightly lower but if the CPU generates less heat than ambient temperature, it is possible for the Heatsink and fan to take away that heat and expel it fast enough so the the Heatsink is always at full thermal load.

 

Well maybe im wrong, but remember all elements try always to stabilize with their surroundings, meaning that if the cooling setup is lower than the ambient temp, it will work backwards, absorbing heat from the ambient air and drawing it to cpu/gpu/chipset, but this is way to simple looking at it, other factors might come into place. I wouldn't expect temps to be lower than ambient air, unless some external thing is influencing this change.

 

Air is an insulator, so the Heatsink will draw heat away from the CPU through the copper heatpipes far faster and more efficiently than it will from the ambient heat in the air.

It is unlikely, but possible given a good enough system. For the Asus cooling design, it most likely isn't though.

 

@OP: I had this problem too for a bit, switched back to 186.03 and everything went away.

 

Mine is doing the same with W7 186.31, I think I'll try 186.03 and see if that fixes it

 

186.03 seems to have fixed it for me. My temps are now hovering at 46-48C

 

Ok thanks stealthl, I'll try these drivers as well.
Btw it's definitely not hardware related (in my case at least) because while gaming the GPU hardly reaches 72°c.

 

I had the same problem with the stock Windows 7 drivers, and also Nvidia 186.81's

The one that works properly for me is 186.82... worked great in Vista, and works perfect in 7 as well. Sits @ 200mhz at desktop and most 2D stuff.
