I just wish I can make it kick in the fan sooner 70 celsius still too high for me the bolt getting laggy for me I wish I can use SpeedFan instead I regret updating the bios I guess they want us reduce lifespan on the cpu also they didn't make feedback forum on 1.07
I updated to 1.07. It work fine. I'm slightly modified fan settings (histeresis to 10C, and lower temps) which makes slow grow from 55C to 75C (takes around 5 minutes), then fan _quietly_ kicks in for around 10 seconds, moving back tempereture to 55C. This is more pleasant to the ear than my old settings, which kept quiet fan, but constantly rotating, and bolt at around 50C. If somebody wants I can show both settings in detail. BTW, bug with hanging in A0 state after booting from windows if using two m2 drives at the same time, is STILL present in the bios. Summary: upgrade, this is the best bios so far.
There is now a special documentation page about fan settings https://www.udoo.org/docs-bolt/BIOS-UEFI_and_Tools/Fan_Settings.html
Slight typo in the above link - should be https://www.udoo.org/docs-bolt/BIOS_UEFI_and_Tools/Fan_Settings.html
