Not yet, I tried the reset but no change. I ordered a new crossover kit, waiting to try that.
Got a tip for us?

@braunico "From my understanding of Cole's build...
So i suspect when turning off the board it shut's down the fans through the mosfet but i don't see how it could shut down the whole PSU (which would be nice).
It would required a mosfet before the entrance of the psu, but then the mosfet would shut down the PSU, not sure the on/off button would work (since the board is no longer on) to turn it back on. For this I was simply thinking a global switch outside of the build."
I was complicating the issue with a switched mains supply to the PSU - for that a simple switch is easiest, as you suggest.
You are right as to what Cole has done.
The green LED provides a constant source of 5v when the board in ON, which triggers the Mosfet board to switch 12V to the fan, through the PWM speed control circuit.
He has modified the original power source circuit - as shown in the image below.
Cole's circuit has the 4 wire PWM controller board after the output of this Mosfet board, as this is for a 2/3 wire PWM controller, and a 4 wire controller is needed for am iMac fan.

Versatile Single Stage MOSFET Board
The Versatile Single Stage MOSFET board offers a switch platform for your Nerfing needs! This board is a bit larger than our mini mosfet board but is our only MOSFET that can be used with a PWM signal reliably and is compatible with any pair of standard flywheel motors we offer.The TRIG/PWM...
