RX 560 fan runs at a high speed upon hitting grub screen

I have an MSI B550 board with a Radeon RX 560.  Once the kernel loads, the fan on the card gets throttled up and it pretty loud.  How can I allow the card itself to control its own speed?

EDIT:

I found that if I do this, I can manually adjust it.  Temporary fix but would really like to know how to allow the card itself to control its own fan.

echo 1 > /sys/devices/pci0000:00/0000:00:03.1/0000:2b:00.0/hwmon/hwmon1/fan1_enable
echo 75 > /sys/devices/pci0000:00/0000:00:03.1/0000:2b:00.0/hwmon/hwmon1/pwm1

I have the same card, and use  radeon-profile-git, combined with radeon-profile-daemon-git.

To make a custom fan curve for my card, I also had to set a command-line parameter for it to work properly.

Runs pretty quiet.

Thanks for the reply.  The single package I mentioned above is a nice little python tool that does it.  You just need to define a simple config.

Re: RX 560 fan runs at a high speed upon hitting grub screen

The amdgpu kernel documentation can be found here

pwm1_enable: pulse width modulation fan control method (0: no fan speed control, 1: manual fan speed control using pwm interface, 2: automatic fan speed control)

But I expect it to be automatic per default.
