Volumio Information
Volumio Version: v2.915

Highpi case with their fan installed
How can you control the fan start and stop based on the RP4 temperature

Hi Qave,
Searching for “Highpi case” i only find one without fan…
Could you provide a link or picture of the case you mean ?
Often, there is documentation from the case manufacturer.

Thanks
you can run the update but never run the upgrade this will break volumio.
this can work on a recent version of Raspberry Pi OS
Does running update enable the fan as it would if I set it to “Enable” in the Raspberry Pi Configuration GUI? My fan is connected to the default fan GPIO (14), so if Update enables it, I would expect it to then power on/off according to the default “Fan Temperature” (which I think is 80c).
dtoverlay=gpio-fan,gpio-fan,gpiopin=14,temp=80000
if the high pitch sound of the fan is irritating, you could try to run it on 3,3 volts instead of the 5volts.
you could put this in /boot/config.txt but this will not preserved it. To make it permanent custom settings need to be added to /boot/userconfig.txt instead.
best regards,

Nailed it! Fan isn’t whining any more. I need to stress it a little to cycle it on and off, but it seems to be working. If the cycling becomes an issue, I’ll try running it on 3.3v as suggested. One change at a time. Thanks.
I should lower the value to 60000, as 85000 is a critical temperature for the rPi. With 80000 your already pretty close to it.
Ack.
