Any idea what is the MAX load of the fan controller on a SP20?
3A Max, the stock fan use 1.75A and we have 6A fuse
Pinout:
1 - 12V
2 - GND
3 - TACHO (Fan output towards controller board for rotation indication)
4 - PWM (controller board output towards fan to set rotation speed)
If you mod the stock fan, you'll loose warranty of course.

Are you 100% on that? The 12V and Gnd listed are reversed from a standard fan pinout.
