Solved: CPU High Temp - Page 2

idata · ‎08-14-2011

Hi all. Just completed a new build with P8H67-M EVO and Core i7 2600K using stock Intel Heatsink/Fan included with processor. Other details probably don't matter, but it is in an Antec Mini P180 case with a Seasonic X-560 (Gold) PS, has 8GB G.Skill Rip Jaws RAM (2x4GB), a Seagate harddrive (SATA) and ASUS DVD Writer (SATA).

After carefully completing the build, I turned on power for the first time, and it powered right up and gave me the BIOS screen. In the BIOS, the CPU temperature shows as 63C-64C at idle! In my opinion this is much too high! I've never seen idle temps this high in any previous builds.

Can anyone suggest any reasons and/or solutions?

The new ASUS mother boards for Sandy Bridge CPUs are notorious for having rather high CPU temperatures when you are in the UEFI (I have one.) There is a FAQ post in the ASUS forums about this, which states the CPU temperature will be up to 20C higher than normal when in the UEFI. Why this happens is not entirely clear, but it seems the new UEFI "BIOS" puts a high load on the CPU. When in the UEFI, none of the CPU power saving options such as EIST or C-States are active, so the CPU is running at it's standard frequency constantly, and the CPU voltage stays at about 1.2V. Next, the CPU and chassis fan speed control software is not active when in the UEFI, and the fans run at or near their full speed. Given that, it is even more strange that the CPU temperature is that high, but it is. I wonder if that reading is actually correct.

So, the CPU temp you see in the UEFI is normal for your board given the information I have seen and my personal experience with a board similar to yours. I don't use the stock Intel CPU cooler, and my temps are lower than yours. Everything is probably fine, just check the temps after booting into Windows. If you use the ASUS temperature monitoring program, do not run any other programs like that (Real Temp, etc) at the same time, as the ASUS program gets bad data when that is done, and you'll see overheating warnings or very strange temperature readings that are simply wrong.

Well, just as really as your other statement:

Not really. I think it is a better solution to their problem.

The statement in bold above is my answer to Roberts statement " Boyett , you are realy tring to put these people in the deep freeze ?? Or you just having fun ??"

The "really?" question refers to your statement "I use one of those liquid nitrogen cups, but when a mother board is mounted in a standard PC case, I find that the LN spills out of the cup."
