How to SLOW DOWN gpu fan with blacklisted driver amdgpu? (GPU passtrough)

Support & Help Requests Hardware

Hi!

Is it possible to slow down the gpu fan of my 2nd card from Radeon when it's driver blacklisted under
/etc/modprobe.d/...?

Because when the "amdgpu kernel module" is blacklisted, the gpu fan of the Radeon card is very loud.

I need blacklisted "amdgpu" for GPU passtrough with VFIO.

With enabled 'amdgpu' kernel module, the gpu fan of the Radeon card is quiet.

Is there a tool/workaround for slow down the gpu fan of the 2nd Radeon card without
enabled driver (amdgpu kernel module?

I want set "pp_power_profile_mode" to '5' - COMPUTE

How can I change the profile mode to COMPUTE?

Added to my rc.local in /etc/

#!/bin/sh

/bin/echo 1 > sys/class/drm/card0/device/driver/0000:04:00.0/hwmon/hwmon0/pwm1_enable
/bin/sleep 1

/bin/echo 45 > /sys/class/drm/card0/device/driver/0000:04:00.0/hwmon/hwmon0/pwm1
/bin/sleep 1

exit 0
