m9750 GPU overheating playin Bioshock.

There is no question that lower temperatures are better. I am aware that the gpu will throttle back if the temp exceeds some predetermined point (I assume
100C) but in my experience games like BioShock sometimes peak in the mid to upper ninety degree range without the lowering of either the GPU or Memory clock
frequencies. If the temps stay in this range rather than peak out once in a while in the 95C + range then yes, it is likely that a peak temp > 100C can occur and result in lowered clock frequencies.
Lowering the temp by 5C if the gpu only occasionally peaks in the mid 90s would probably not have much effect on game performance.

 

Depends on the game, some games push the GPU much harder than others and if you have a common CPU/GPU heatsink then pushing either CPU or GPU harder can cause issues.

Personally I think anything over 80c with 30c ambient temperatures is unacceptable.

 

Well, guess I won't be buying one even if they do give the 8800M GTX as an upgrade option. Unless, of course, they've solved this with the newer ones. Have they?

 

I thought it was 1 fan for the cpu and secondary gpu, and one fan for the primary gpu

 

it is the CPU and secondary GPU.

I just randomly glanced in this sub-forum... forgot all about this thread.

I was probably thinking about the m9700, which had one fan for both cards.

 

oh so if I get a single GPU it's fine? As in no thermal design flaw?

 

Yes since it has it's own dedicated fan. At idle, my primary GPU runs 10 degrees cooler than my secondary GPU. Also, the CPU should run cooler as well since there is no secondary GPU to add heat load to the second fan.

 

hmm well this is a little late to post this a 6 months later but my 9750 idles at ~70 degC and gets to ~89 degC when running 3dmark with a t5500 in it but when i had the t7600 in it the temp would rise a bit higher but also i would experience horrible fram rate drops like from say 90 fps to 7fps in a graphic intense scene on a game such as an orbital strike of bf2142 or on COH an artillery strike it would drop from ~40 fps to about ~2-3 fps and hold their after the intense scene for about 20 seconds making playing games really difficult. I have not experienced it with the T5500 and I plan on putting the T7600 back in and checking clock speeds when that happenes.
