Hello,

Whenever I resume from sleep, the speed of chassis 1 fan becomes bugged.

Basically, it rotates around ~30% slower than what has been specified in BIOS. Before going into standby, everything is OK of course.

Can you please help with this issue?

Running 4.90 BIOS

Same Board, same BIOS. Not experiencing that particular problem.

Sounds to me like its either some odd corruption to the fan setting in FANtastic tuning, or possibly, some other ACPI or power setting buried deep in the BIOS somewhere.   Did you set the fan speed in BIOS or in Asrock's tuning software from windows? The fan speed setting doesn't stay set if you set the speed from the Windows software correctly. It only does it from BIOS.

Also, a silly wild a** guess, did you run the FanTuning feature before setting the actual fan speed in FANtastic tuning? I've had wierd behavior when not letting the board measure the fan speed via PWM before setting the fan speed in BIOS.

I noticed the same behaviour, but don't recall which FW version.

I started using the other fan connector.
