CPU temps a little too high in BIOS?

This is my second build, using an A10-6800K. I'm using the stock cooler and the http://www.newegg.com/Product/Product.aspx?Item=N82E16813128659 motherboard.

Originally, when my computer didn't boot, I did something silly by lifting and reinstalling the heatsink. When I started seeing temps around ~55 C in the BIOS, I assumed I had pockets of air trapped between the CPU and heatsink because of my lifting it. I ordered some Noctua NT-H1 Thermal Compound and I've used cotton swabs and 70% isopropyl alcohol to clean off my CPU and heatsink before applying the new stuff.

I've done this twice now, and both times I've seen the CPU temp slowly rise and settle in the mid to high 50's. Currently, it's steady around 57 C. The fan RPM is pretty steady around ~2800 RPM. All the cables are routed behind the motherboard tray, and the only thing that's even close to obstructing airflow from the front case fan is part of my 24-pin cable.

Is it possible that my BIOS isn't correctly reading temps? Also, does 2800 RPM and 57 C for AMD's stock cooler sound about right? I haven't installed the OS yet because apparently the max operating temp for this CPU is 75 C, and I'm not sure how much load there will be on the CPU during the install, leading to higher temps.

Any thoughts?

Try downloading hwmonitor and compare the temps between it and the BIOS.

After posting this I read you didnt install the OS yet. XD


Heh, yeah, I was just a little worried about whether installing the OS would cause the temp to rise significantly higher and overheat. Any idea if the CPU load during an install of Windows 7 is particularly high?

I am not certain if I would have to guess it would have to be somewhere around 75% maybe. I know the usual idle temp for the 6800k is 28-35c and the normal load would be 50-55c and the max would be around 74c.

I just found this forum posting some people had BIOS that were reading temps incorrectly that might be what is happening with you as well.

I have also read that UEFI BIOSes push CPUs at 100% load so it might be showing the highest value not idle temp.

Ah, thanks for finding me the link. :)  Yeah, I feel a little better now, I think I'll go ahead with the OS install and see what things look like from there. Fingers crossed...

If you can get the OS installed without any problems i would install a couple programs hwmonitor, speedfan, and core temp and compare. If they are all reading different then you know it probably isn't reading correctly.
Here is another link to a thread I found as well if you want to read while you install :p

I've currently only installed CPUID HWMonitor so far (might check others after Windows Updates and whatnot finishes). Looks like idle temps are in the low 40s according to that program. Not amazing, but I certainly feel better about it. I'll use if carefully over the next day or two and see how it does under higher loads.

Thanks for your help. :)

Glad I could help! 40s sounds about right my i7 sits around 43 at idle and I could organize my cables a bit more haha.
