CPU overheating in BIOS [ASROCK FM2 A78M-HD+]

[Dan.B]

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: 500W

Everything works perfectly in windows (good temperature, memory, etc) but when i go to Bios, my cpu temperature is rising from 37C to almost 62-70C in 2-3 minutes and i don't know why. I checked all the setups also i used "default settings", update bios but without succes. I changed the thermal paste, CPU fan and the chassis fan...same problem. The machine is not overcloked. Should i'll be worried about this problem or everything is normal?

Thanks in advance!

My rig does the same thing in bios mode. I think its a combination of different thermal sensing in DOS then Windows and fan speed control as well. Just don't hang for hours in bios setup and things will be fine. If it did this in windows, then I would be concerned.

What is the temperate range?

I think this is not normal, anyways somehow i managed to control and reduce temperature to 49-50C by lowering the voltage on CPU from 1.5V to 1.3V and rising the CPU Fan from Standard (800 RPM) to Performance (1320 RPM). You can try with your rig and see what happens. With a little research on other forums i discovered that many people have this problem. I think is a error of coding in UEFI/BIOS reading the temps.

My temps average 22 on all 4 cores in Windows (at idle) with a 4.75 overclock.
Boot into bios and it jumps to 51. I've seen this with other boards I have owned., and I am not really concerned.
