Axt1800 running hot, 75C

[Johnex]

Lower down in the thread you can play around with the PID for the fan controller:

I found a way to set the gl fan!

So this pdf on the mango SOM used in AXT1800 mentions the temp range for the commercial boards (which I assume this is) is 0-65C. The gl_fan app only polls the temp and sets the fan every 20 seconds, so If you have a large load spike I suggest bumping the integral -i and derivative -d values of the PID loop as it will not have very many readings to work with to ramp up or smoothly change the speed. In other words- If the load spikes you want the fan to come up to speed quickly. If you only se…

I didn’t really get it to work, for me the fan did not run at full speed even though it needed it to lower the temperature, but i just put the values @nopro404 suggested. Maybe you can give it a try and see if it works for you.
