Indieshack Posted July 4, 2020 Share Posted July 4, 2020 I just started RockPro64'ing (though been using Linux for about 25 years) and bought the low profile fan with the RockPro64. Armbian (downloaded today) installed fine, sees my NVME etc. so all good. The only issue I have is that once the OS starts up the fan comes on and never stops - it seems to be running 100% all the time. It the speed meant to vary? And is it meant to turn off sometimes when not required? I'm wondering if I am I missing a config file entry for this. Thanks for any assistance and well done on the distro.

soerenderfor Posted July 6, 2020 Share Posted July 6, 2020 If you want to change the speed. The place of the fan is different on some kernels, you can check it: sudo find /sys -name pwm1 | grep hwmon And you will recive a text, write that. nano (insert the text you recived here) and then change "255" to whatever you want.

jiko Posted July 7, 2020 Share Posted July 7, 2020 (edited) I modified a script from another thread for my fan via the SATA hat on a NanoPi M4v2: https://gitlab.com/snippets/1993413 I had some strange behaviour with the needed PWM values getting inverted between reboots, but that seems to have settled now.
