Trying your software. When my router disconnects, 5 minutes after my s9 starts speeding up the fan to 100%, up and down constantly.
When the router connects back all gets ok.
I have settled manually the fan to 40% and this is very inconvenient, can i avoid this behavior?
A lot depends on what speeds you are doing the unit at.
Here is a 1 board build with a lessor fan.
the single fan is low speed about 1700
set to 400 mhz and 8.1 volts
