[Elecraft] KPA1500 fan speeds and fan noise

[Bill Stravinsky]

 That doesn't move any air across the heat sink or solid state devices that need the air.  The air that comes out of those vents starts at the fans in the rear.

 All,

My solution is two 4.5-inch, 48-volt dc muffin fans sitting on half-inch 
tall rubber feet covering the top exhaust vent on amp. They are running on a 
19-volt supply at a slow but effective cooling speed and are very quiet 
(drawing air upward). During normal CW rag chewing the main fans do not come 
on -- a vast improvement for a few bucks. When you go portable, just leave 
'em home.
