[Elecraft] Any larger or more efficient heatsinks available for the K2/100PA (radio lid/top)

[Fred Jensen]

Before selling my KPA100 and KAT100, I used my K2 in RTTY contests.  I 
stuck an old computer brushless DC muffin fan down over the warmest part 
with a little square of velcro, blowing down.  I could run 100W 
[generally didn't but could] and the heat sink stayed almost cool.  I 
don't think you have to move very much air over it to keep it cool.
