[Elecraft] Re: Barebones K2 Amplifier

[Don]

Many of us place a small muffin fan on top of the K2 heatsink.  I have my 
muffin fan housed in a small plywood box (blowing down at the fins) with a 
resistor in series with the fan so that it turns fairly slowly and makes no 
noise at all.  With this auxillary cooling the noisy little fan in the 100W 
amp almost never comes on.  I often run CW at 100 watts output and the 
internal fan only comes on after an especially long transmission.
