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

[David Wilburn]

With so many high volume low speed (and thus low noise) fans out 
there,  I would have a hard time justifying doing more than setting 
one up on the heat sink on top (for 100w version).  But operating 
styles and locations vary, so YMMV.
