All,
J3 is a constant supply point. I believe what Norm is looking for is the P3
header on the KN-xxx. Pin 1 is ground and pin 2 is hot. This will supply
voltage to a 5v fan, that is controlled by code to turn on when the board
temperature reaches 45 degrees C. Once the unit has cooled to 30 degrees C,
it will turn off. This code was introduced in version 4.44.

Digi-Key has lots of fans. I use a 24vdc ball bearing fan on my KN205's. I
don't use the header yet, but plan to investigate using it.
