[Solved]Bios and HWMonitor Temps - drastic difference

post #1 of 12
Thread Starter 
So I have my E6600 OC'ed to 3367 from 3066 and when I opened up HWMonitor to check temps after running Prime for a few hours (no issues reported) I was shocked to see the CPU temp at 99C. I immediately rebooted and went into the BIOS which showed my CPU temp at a comfortable 58C.

I'm inclined to trust the BIOS, but just unsure enough to ask for justification of that inclination.

99C sounds unreasonable. Your computer would probably shut down if the temps were actually that high. Try a different temp monitoring program, such as RealTemp, hwmonitor, or aida64.

Your temps are fine, don't even worry about it. Bios is correct.

FYI, Intel proc's have built in circuitry that shuts it down if it reaches high temps... Yes, always trust BIOS temps over software I use coretemp and its freeware and works great! I just recently used it to OC my QX9750 to 3.2.

You are all wrong.

If HWMonitor was running while Prime 95 was running, load temps were shown.

The BIOS temps are near idle, and are going to be vastly cooler. It only takes a few seconds after ending a load for CPU temps to drop to within a few degrees of idle.

Chances are they are both correct.

58C is very hot for sitting in the BIOS, and I would not be at all surprised to see 99C under heavy load.

Intel CPUs won't trigger throttling till their TJmax (usually 85-105C), and will not auto shut down till 125C (unless you have manually set a lower option in the BIOS).

Edit: I believe the TJmax for a E6600 is 100C, which explains why 99C was shown. It would have gone higher but was being throttled.

I would check the mounting of the cooler. Push pins probably aren't engaged correctly.

Also look into Core Temp.
Works great in the system tray and helps me make sure my stock air can handle my clocks

I had prime and HWM running together....the 99 was legit....I'll be back in a few once i check out the seating of the CPU Cooler. I hate the OEM one from intel....

Perhaps you should read the post better, let me bold the important part for you:

After stressing the CPU to 100% and immediately rebooting, it is completely unreasonable to claim 58C is the temp he would normally get in the bios

Thank you Blameless. Sometimes it takes some one removed from a situation to point out the obvious. And this PC is my first ever build, so the insight is GREATLY appreciated. +Rep

One of the mounting pins on the CPU cooler wasn't pushed down far enough. I actually removed the mobo from the tray to get enough leverage to make them all seat properly without flexing the board.

I've been running HWMonitor for 30 minutes now and the MAX temp while the stress tests are running is 58C, which was my idle temp previously.

Idle temp holding at 43C.
