I just wanted to say that I just replaced my fan1 mosfet as I must have shorted some wires during installation. I don't have a hot air station and I'd never done any surface mount soldering before, but I did get it replaced and with no collateral damage. Had I known the package with the mosfets was getting delivered that day, I would have waited until afterwords for my normal coffee break as the hands were a bit jittery after that caffeine injection.
