I cannot find the temperature throttle value of these processors but you can try lowering the AC values with 5-10 degrees and put the Fan Duty Cycle above AC1 to 50% and see how it runs. I suppose (but not sure) optimum CPU temperature is between 70-80 degrees.
A new version is available here https://www.udoo.org/docs-bolt/BIOS_UEFI_and_Tools/BIOS_UEFI_Update.html it's version 1.08 .
That page has this line "If you are one of the Kickstarter users and you see a Green Dot on one side of the fan, please check the Fan Settings page." Since I do have one of those fans I clicked on the link but it gives a 404.
I suppose you have found it by now. If not, you can find the fan settings page here:https://www.udoo.org/docs-bolt/BIOS_UEFI_and_Tools/Fan_Settings.html
Is there any update as to when the formal release of the BIOS will be available (and what issues if any might be addressed)
