CPU overheating in BIOS

[Neeo]

I just build myself a AMD gaming gear with:

 

Motherboard: ASROCK FM2 A78M-HD+

CPU: AMD A8-6600k 3.90Ghz

RAM: 8gb 1600Mhz

GPU: Sapphire R7 260X OC 2GB GDDR5

PSU: 600W

 

Everything works perfectly in windows (good temperature, memory, etc) but when i go to Bios, my cpu temperature is rising from 45C to almost 90C in 40-50 seconds and i don't know why. I checked all the setups also i used "default settings" but without succes so, i need some answers from the experts  .

 

Thanks in advance!

Does the fan spin up properly while in BIOS?

[Enderman]

first check that the CPU fan is working

remount your cooler and replace the thermal paste with some MX-4

make sure you clean the old thermal paste off of the CPU and cooler with some alcohol

[RossMadness]

Make sure you have the CPU fan connected to the correct header on your motherboard. This will allow the BIOS to raise and lower the RPMs as needed. Also, make sure that the CPU cooler itself is properly and firmly fastened to the mobo in order to best transfer heat from the die through the thermal paste into the heat sink. 

Are you using the stock heatsink/fan or is it third party? Also since Windows is reading the CPU as fine and the BIOS is showing different results, visit the manufacturer website and make sure that your BIOS is up to date.

Yes, i use my stock fan for the moment because i run the system without overclocking anything.

I did that, without succes unfortunately.

Then on to the second part of my post: Have you checked to make sure that your BIOS is the most up to date version?

[VincentiusIV]

what voltage is the cpu running at?

Is up to date 8/21/2014.

what voltage is the cpu running at?

1.384V

Any ideas? Please, i really need help...

[settlwlvs]

I'm only suggesting these because the most obvious ideas have already been stated...

 

Are you using a fan controller software? I doubt it would cause this, but you never know.

 

Also extremely unlikely, your software and BIOS could be reading temps from two different sensors. I know Corsair Link and HWMonitor always give me different reads at the exact same time. If nobody can think of a better solution, see if using a different motherboard makes any difference (but only if you feel like rebuilding your entire rig on the off-chance).

The fans are controlled by the Bios, also i replaced the fan stock on the CPU today. As for the sensors temp, i tried everything on Bios...

take off your cpu cooler, clean it, add new thermal paste and check that the fans spins up at bios.

[The_Evenger]

this may sound obvious but have you tired running it with the sidepanel off? (you didn't post your case) and if you have a powerful blower fan or something like that laying around try blowing that directly towards your CPU heatsync, and i mean a powerful fan, not some cheap thing.

Like i said in the previous post, i changed the stock fan  (new thermal paste). With 30C i have 800-870 RPM.

I have the sidepanel off, also i have a good fan on cpu. This one:

Many UEFI BIOS out there make the cpu temps shoot way up. Seen it many times.

Indeed! With a little research on google i discovered that i'm not the only one with this problem...Well it looks like there is no "cure" for my problem at the moment, anyways thank you all for the support. If i find a solution about my problem, i will post here.

[Tazzy2040]

have you solved the problem ?

[thorpj]

Unless you're going into the BIOS all the time, then adding onto what bigdaddy said, it's just a thing with BIOS UEFIs, it shouldn't be a problem.

 

If you're going to be spending a lot of time in the BIOS on that PC, then my comment is defunct.

After a little help from ASROCK support, i managed to obtain a stable temperature (49-50C) lowering the voltage to CPU from 1.5 to 1.33 and rising de CPU fan speed to 1320 RPM (was 800 RPM).The question is: This temperature is normal for BIOS? I hope this information is useful for other people with the same problem.
