okay so the card idles at like 60c when i throw it on kombustor its ramps up to 100c in like 3-5 seconds and then a black screen comes up and i have to shut off the PC happend in my PC and happend in my buddys PC the stock volts on that card is 1.000 which i thought was kinda high for stock settings the core clock is 725 stock i lowered the volts to around .980 problem still existent.

Neither of those temps are normal - but you already knew that wink.gif

Can you confirm the fan(s) are at 100%

Addit: Are you using a stock HS or an aftermark HS?

yes the fan is at 100% manually set. but even if it was at 30% i wouldnt think the card would overheat that hard at idle

Did you check to make sure it's spinning? If the fan is spinning then this must be bad contact between the GPU and heatsink, so carefully disassemble it to change TIM again, keeping an eye out for any mistakes you might've made the first time, then when applying the TIM and reassembling be very meticulous.

Since the PC is failing it sounds like it actually is getting hot but it may be worth double checking temps with multiple programs. Some programs are glitchy in general, or glitchy with certain hardware. If for nothing else, you've eliminated another variable.

When you set the fan to 100% can you hear it get louder ?
post #18 of 27
Regardless of fan speeds, the card won't shoot to a 100c load. So it's not the fan. And it's not a faulty temp sensor because the PC shuts down. It sounds like the heatsink just isn't making proper contact with the IHS. Remount it again.

Im tending to agree with this observation... time to remount my friend.

I tend to agree i had a old 6850 with a faulty sensor that would get stuck but his is changing at idle and load so sounds like a mount issue.
