Official Case Fan always at max speed #33

Hi, I recently installed Windows on my Raspberry Pi 5 with the official case, but the fan in the case is always running at max speed. Is there any way to fix this issue without replacing the fan?

As far as I see correctly PWM is not yet supported/implemented: https://github.com/worproject/rpi5-uefi?tab=readme-ov-file#supported-peripherals-in-uefi (RP1 PWM row).

Replacing the fan won't fix the issue. You need to wait till PWM control become supported.
