Hello there,
I need some tips to diagnose the pwm circuit.
-----
I've used an Arduino and tested the 5V, PWM fan is functional.
However, I don't think the motherboard is generating any signal out of the pwm pin.
I don't have an oscilloscope with me ATM but the voltage meter says 0V.
I can't seem to capture any signal through Arduino either.
I've also run continuity test cannot find any short circuit either.
----
The motherboard schematic and boardview can be found in this post...
