All(some) resources to quiet down your proliant :)
I have lost interested in this project so trying to just tie up the ends so people are not complitely stranded.

This server has a weird issue where even though the server is off fan 6 receives 8-9V and since arduino shuts off the fan gets no PWM and goes to full speed. Easiest fix is to apply power from fans +12v pin to arduino VIN pin so arduino stays on with the fan and sets its speed to 15% or whatever is default. In future arduino code I could see if I could detect this condition and make it fully stop the fan.
