99°C on 6950

post #1 of 4
Thread Starter 
Hello, sexy people! tongue.gif

I have for you, guys a situation to be solve... and that is: When I'm gaming, or benching, you know, giving my cards a good use, they reach 99-105°C no problem. They are of-course on stock settings right now 'cuz of the high temps. While I don't consider this a problem, since people bake they cards @ ~150°C for an hour or so and the card still work fine, I do have an issue where the GPU Mhzdrops. Its so annoying.

This Pic will show you what I mean: (Data of OCed Cards on a Metro 2033 benchmark)


Now, this are my lame-cooled cards



I did once took apart one card and found out ONLY the chip is being cooled. Nothing more, nothing less. Just the GPU. The Vrams and all the other goodies are not being cooled. They are left to their own luck.

I wanna know if anyone here knows what causes GPU Mhz to drop... Is it because of the high GPU temps? Or the Vrams and all that stuff getting too hot?

I'm thinking right now that its the goodies like Vram, since the card run @~100°C on a metro 2033 benchamrk and only on the last of 3 runs I can see the frames drop.


Thanks a lot! biggrin.gif

I have an easy answer for you, get an acellero extreme aftermarket cooler. If you don't want to do that then go and replace the thermal pads etc on the cards. Those HSF aren't the best to be honest.

Good lord thats hot.

Space out your cards as much as posisble on your motherboard in different PCIe slots and remove the cooler and repaste the thermal interface material on your cards. Ensure they are gettting lots of airflow and maybe even run a custom fan profile.

They have one PCI slot clearence between them. If I go down another slot, the 2nd card would get cero flow, since would be pretty much laying over the PSU. I don't have the side panel on to give the most possible air to the cards.

I'll try to change th thermal paste. I have done it in the past with almost no positive effect, but might be worth do it again biggrin.gif

I'd rather sell the cards and get a pair of EVGA -double fan 660ti cards then getting the coolers. I would spend the same amount of $$ and have some better, cooler cards... Thanks for the input tho thumb.gif
