I've installed Coreboot on ASUS F2A85-M. Everything works fine, but the CPU overheats when doing something intensive (like video playing) and the OS crashes. Browsing the internet and watching movies doesn't make it sweat. I use FreeBSD 11.0-RELEASE and Gentoo Linux.
My CPU is X4 750k. I lowered the RAM voltage to 1.35V but it doesn't really help. Enabling power saving features also doesn't make a difference. Everything works fine on vendor UEFI, so this issue is specific to Coreboot. Any idea what I can do?

Would be nice if you had some temperature figures.

If you notice a difference in CPU fan speed, that would be my guess since it looks fan control (super I/O) is rather minimally configured in coreboot.
Kind regards.
Hi Piotr,
Are you sure that it is overheating? I would suspect RAM issues if you see some crashes. Is your CPU Trinity or Richland?
If you modprobe it87 and you have some more recent kernel, you should see some temps reading:

Before investigating the software methods, in this situation I would have tried to: using some great thermal paste, cleaning the dust, and - most likely - switching to a manual fan control: there are the hardware fan control adapters, and if you don't have those - temporarily you could just wire your fan so that it will always work on the max speed instead of taking the fan control commands from the motherboard

Thanks!
I'm only starting to get some knowledge about Coreboot and I didn't realize that I need to configure fans in the OS :) Now everything seems fine, except that FreeBSD doesn't seem to have a way to configure fan speed...
