Here's the Setup Antec 900 Two Corsair 750HX 2x XFX 5770 Gigabyte GA-P55-UD4P Intel Core i5-750 Coolermaster RR-B10-212P-G1 4x 2GB Crucial DDR3-1333 2x WD Raptor 300GB 2x WD Raptor 74GB Anyways, with that out of the way... Started doing some tests with prime95 64bit and I hit 99C in 20 seconds or so using the bone stock config. Happens even faster if I try to follow the overclocking guides from Tom's, MaximumPC or NCIX. I used Arctic Silver, and I've already re-seated the heatsink twice. Case has 4 fans, plus the one on the heatsink. Just doesn't make any sense. Please help a guy out......
Hi, try taking the cpu itself back out and re-seating it, also I think u have to rotate the push pins on the stock heatsink to lock it down propperly if u haven't done so already. I find that the best way to apply thermal paste is to use a pea sized amount and spread it all over the top of the cpu evenly using cling film over your finger. If this doesn't improve temps I would recommend investing in an aftermarket heatsink. Hope this helps.
My only thought is a possible defective heatsink, or a defective temp sensor in the chip itself, If it is seated properly and the fan working as it's supposed to and it's overheating then it's probably a defective part. you do have to push the pins down, from my experience with their C2D chip it can be a pain to get them all clicked properly.
Hitting 99 at stock is pretty extreme. What temps are you getting under idle? As previously stated, try to re-seat the HSF, but also when running prime, is the Heatsink actually hot to the touch? Could be a faulty temp sensor.
Faulty temperature sensor is my guess. Fazed's right to ask - under normal operating what does it report? What temps is the motherboard reporting? And is it hot to the touch?
He's not using the stock cooler: Coolermaster RR-B10-212P-G1 Either: Faulty temp sensor in CPU Heatsink not installed correctly
Interesting. I launched the gigabyte utility and it shows the CPU temp at 33 idle and CoreTemp 0.99.5 shows it it 44.
