Kevin -
Don may be correct in this case. I have not seen a K2/100, and if
indeed air is already being directed through the heat sink, then you
certainly don't want to set up an opposing airflow. Does the K2/100
heat sink have holes? How does the air flow from the internal fan reach
the heat sink? My example, in my last message, is for the general case
where there is little or no air directed to the external fins of the
heat sink.
My K2 is the basic version, no amplifier included. The photo of a K2/100
on the Elecraft main page does not show how the air from the internal
fan is routed, and the internal photo of a "folded out" K2/100 is not
much more help. I can see the fan in the photo, but that doesn't tell
me much.

Kevin,
The easiest solution is to simply lay the fan (horizontally) across the heat
sink fins. Suck the hot air away from the heat sink, that way it works in
tandem with the internal fan rather than fighting the internal fan
airstream.
