[Elecraft] Successfully using a micro fan to keep K2 cool

[Don Ehrlich]

This has been suggested many times by others.. now it is my turn to repeat 
it I guess:

I mounted a 12 volt  4 inch muffin fan in a simple enclosure and placed it 
on top of my K2 blowing downward.  I put a suitable resistor in series with 
the 12 volt supply so that the fan turned slowly and made no noise at all. 
The muffin fan ran all of the time and the little microfan in the K2 
(almost) never came on while running cw or ssb.
