Keeping Raspberry Pi 5 cool on large compiles


 

I found a page that describes how to continually run the fan in the Raspberry Pi 5.? I made these changes and the Pi 5 never got above 72C while building fldigi with "make -j4".? Max temp for the Pi 5 is 80C-85C.


To summarize, place the following lines into /boot/firmware/config.txt and reboot.

dtparam=fan_temp0=40000
dtparam=fan_temp0_hyst=10000
dtparam=fan_temp0_speed=125

One of my Raspberry Pi 5's has been modified and is sitting right in front of me.  I cannot hear any noise from the fan.  So, I see no downside to this.
