Troubleshooting • Re: Fan not working

Does it run for a short time at boot ?

You shouldn't need that dtoverlay.

To lower the operating temperature try this in config.txt

dtparam=fan_temp0=30000
dtparam=fan_temp0_hyst=5000
dtparam=fan_temp0_speed=75

dtparam=fan_temp1=40000
dtparam=fan_temp1_hyst=5000
dtparam=fan_temp1_speed=128

dtparam=fan_temp2=60000
dtparam=fan_temp2_hyst=9000
dtparam=fan_temp2_speed=192

dtparam=fan_temp3=70000
dtparam=fan_temp3_hyst=9000
dtparam=fan_temp3_speed=255
