Is Nvidia or SpeedFan right?

post #1 of 12
Thread Starter 
I have an NV Silencer Rev 5 on my XFX 7800gtx and i just applied arctic silver to the gpu and now my temp in the nvidia control panels idle is like 70 idle which is WAY too much. The thing is before I applied the AS5 my idle was around 46. Speedfan shows my idle as 46 and i dont know which one of the programs to trust. My idle on the control panel is 115C + . Whats weird is when i put my hand out to feel the air coming out of the cooler its cold. Wouldnt 115C be super hot?? What sucks is the core slowdown thing for my card is 115C, so when nvidia thinks my card is at 115C it slows it down which gives me like 10 fps in bf2. Any suggestions?

I'd be careful, the driver temp monitor is probably correct. I had a problem with my silencer on my 6800GT not making full contact on the die so it didn't cool any better than the stock heatsink, sounds like you're having a more severe case of it. I'd break it down and reapply or replace the heatsink before you damage the card.

Yiffy, wouldn't you trust SpeedFan? Since it is showing the same temps that it did before this "problem" and only the nVidia drivers are reporting BS 115c temps?

One, how could simply applying AS5 all of a sudden screw up the driver temperature reporting? Two, I would trust the driver temperature reporting, which is designed specifically for nVidia video cards, over the generic Speedfan registering, which is not specifically designed for nVidia cards. Three, AS5 is a lot thicker and flows less easily compared to standard silcon thermal interface materials, so there's a high probability that it's not making good contact. And four, I always take the highest temperature readings as being true. As the saying goes, better to have too much than too little, so I'd rather take strides to make my system run cooler even if the temperatures are already low rather than assume the one reporting them as low is correct and have it turn out they're not and end up with a dead $400 video card.

There is always felling the top right above the core if its scorching its most likely the 115 you persume it is.

yeah but Yiffy, he clearly said that the air coming out of his case felt cold, so even if the GPU cooler was 3 feet away from his GPU core and it was 115c I still bet the air coming out the GPU cooler would be pretty dang warm. And I would USUALLY agree with you about the drivers being more accurate but I seriously doubt he could have gone up to 115c (which just so HAPPENS to be the core slow down temp, a bit odd, no?) plus, I was the one who applied the AS5 on there and believe me, it wasn't the best I've done but it should have been plenty good enough.

If the heatsink isn't touching the core and conducting the heat off of it, how is it going to warm the air blowing over it? Chosen's advice is best, go touch the metal plate behind the GPU. If it's schorching hot, break it down and reapply and don't let Remonster near your computer again. If it's not, get new drivers.
