I have official v 20 firmware on the mb..

CPU FAN attacched to a PUMP (Enermax liqmax II 240) at full speed
CPU OPT attacched to radiator's fans with custom curve
FAN 2 and FAN 3 attached to case fans with custom curve

I tried uninstalling SIV and to manage fans via UEFI but in each case the CPU OPT stop working when resuming from a suspension (Windows 10). It seems that CPU OPT disappears from PC (HWinfo and other tools didn't see the CPU OPT fan). The problem can be solved only rebooting the PC.

To avoid CPU burn I had disabled PC suspension...

Some one can help me?
Thank you
