I installed Debian 10 on a Raspberry Pi 4B with an official POE hat.
I need to configure the fan to control the CPU temperature. This is possible with Ubuntu based on this article.
On Debian 10 there is no /boot/firmware/usercfg.txt file, so I tried this in the /boot/firmware/config.txt file. This had no effect. The CPU temperature is not controlled.
Any help would be greatly appreciated.
Many thanks
Johan

Re: Raspberry Pi 4B POE+ fan control
Thanks for your response @Aki. It looks like I will have to upgrade to the latest Debian to get a 5.13+ kernel.
I will do this when I have some time.
This link for Fedora also seems helpful.
All the best

Re: Raspberry Pi 4B POE+ fan control
Did you consider passive cooling for yours? No moving parts, it doesn't draw extra power to run the fan and doesn't make noise. I use it for my 4B, and I couldn't be happier.

Re: Raspberry Pi 4B POE+ fan control
Thanks for your response @Hallvor.
I use the official Raspberry PI POE hats in this 1U rack configuration.
I therefore do not have passive cooling as an option.
Cheers
