Fan Control doesn't release fan control to the BIOS when hibernation started

[cablop]

In most scenarios, hibernation starts and Fan Control was controling the speed of fans, the speed remains at how Fan Control determined during the hibernation process, sometimes it is too slow. System perform some tasks during hibernation causing the CPU temp to raise, but fan speed doesn't raise.

When testing:

• Turning the PC on again, just after hibernation, shows the CPU with a pretty higher temp than expected, sometimes around 80°C, because fan was too slow during hibernation, and remained like that.
• Enabling BIOS alarm to test if CPU temp went above 70°C worked and the beep alarm constantly sounds during hibernation, but fan speed not, unlike what was expected.

Expected scenario:

• Fan Control gives control back to BIOS/MoBo when hibernation starts, so Fan Control can go to sleep but system prevents damage to CPU during the hibernation process.
• Fan Control reclaims control back after waking the PC back from hibernation.

Alternative desired scenario:

• Fan Control sets CPU fan speed to maximum, so Fan Control can go to sleep but fan speed prevents damage to CPU during the hibernation process. (But i think this one is not easy cause no gradual stepping up of fan speed)
• Fan Control reclaims control back after waking the PC back from hibernation.

What kind of hibernation/sleep are you talking exactly?

In my book hibernation is a RAM dump on disk, and the PC basically shuts off. No power in the system. When booting back up, the hibernation file is restored onto RAM, restoring pre-hibernation state. In your case, it seems like some kind of sleep but with the system still able to do some background work?
