Active Cooling 5v brushless fan with Motor Speed Controller soft PWM
#8
   

The pic above shows another of my RPi units (in the C4Labs Zebra case) with the in-line fan motor speed controller transistor (2N2222) and the 1K ohm resistor on the base lead running this time to pin(11) on the PI bus.

In this case I not only had to swap the 5v and ground leads in the standard 5v plug, but I also had to trim the plug to get it to fit into the slot provided on the C4Labs case top bezel. This will probably be the same situation on the PineA64 C4Labs case as well.
