SLI temperature question

[Wall7486]

Well, just curious to know that if its normal that my first 6800GT runs at 50C GPU/ 74C Ambient( Full load: 54C GPU/ 82 Ambient), and my second 6800GT runs at 47 GPU/ 64C ambient ( Full load: 50 GPU/ 68-70 Ambient). The first card jsut runs so much hotter. I have the Lian-Li 1000B case. I was just wondering is this normal for a SLI setup.

That depends. Do you have a fan placed near your 2nd card? Otherwise, differing temps are perfectly normal, although not to those extremes.

Yea just looking inside my case, I realize the second card is closer to the 120mm fan, lol. Sadly this shows my lack of visualization.

If by "second" you mean the card not in your primary slot, it also has the advantage of not having a 6800GT below it radiating heat up into it's HSF?

Yep, that's definitely a good reason (as well as it's being sandwiched between a hot GPU and a hot CPU).

But, also, what drivers are you running? Some of the nVidia drivers have a temperature bug in that the readings are a bit off. You have to go into your overclocking settings and overclock the 2D core to 402. You will see the temps drop immediately.

I think you got those GPU\Ambient temps mixed up. If not, those GPU temps are a bit too low, and the ambient temps are ridiculously high. However, a temp variance is perfectly normal, as all cards are different, and some may have hotter GPUs\memory than others.
