I've been having a problem with my setup for about the past two months. The computer shuts down under CPU load. The problem is present in both Linux and Windows so it is not a software issue.
I've run speedfan and Everest and it APPEARS that one of the cores on the CPU goes above 85 degrees VERY quickly under stress (although strangely not under a Prime95 torture test).
I tried replacing the CPU (an E8400) with another CPU (an E5400) and the problem STILL persists, Everest reports CPU Core #1 flying up to above 85 degrees under any stress (specifically I've been using Diablo II, but it will go above 85 decoding video and such).
How could this same problem persist after switching CPU's? It leads me to believe the sensor labels are wrong.
Set up is:
DFI Blood Iron P35
Intel Core 2 Duo E8400 (and E5400)
4GB OCZ Platinum DDR2 Ram
Geforce 8800 GT
If anyone has ANY ideas about this I would be indebted greatly.

That's what I'm thinking too. This thing has been running for two months like this, numerous shutdowns @ the 85 degrees mark.
I'm going to try changing it right now - but interesting to note - I loaded 'optimized defaults' in the BIOS a couple days ago and the problem still persisted so not really sure what's going on. Going to try manually adjusting voltages now.
(1) Incorrect CPU voltage - Have you downloaded and installed the Latest BIOS??
(2) what HSF are you using? If Stock, ditch it as they along with Push-pins are louy.
Note you tried two diff CPU's with same result. (On installation, you should always check CPU voltages and temps.) Once you have corrected voltage, the next suspect should be the CPU cooler, not making good contact aver the one core overheating.
It is possible, since correcting the abnormally high voltage was a "after-the-Fact, you may have 2 bad CPU's now.
After CPUz reported 2.2V I restarted and looked in the BIOS without touching anything the BIOS reported 1.1V. Then loading fail-safe defaults Cpuz reports 1.1v.
Do you really think both CPUs could be fried in the exact same fashion? And also do you really think that either of these CPU's could run for any length of time at 2.2V without immediately becoming unstable?
I'm no expert here by any means but the system is stable. It just shuts down when one of the temp readings hits 85C under load.
Good points. I aways compare the 3rd party software reading to Bios, or manuf software. It's posible that CPUz was reporting it incorrectly. How long the CPU would last @ 2.2 V - I'm not qualified to answer that.
I noticed that speed fan that most of your voltages are Incorrect, appears incorrect reporting and not bad voltages.
Does DFI have a software utility for monitoring system (simular to Gigabyte's Easytune 6 utility).
