[Elecraft] Cooling fans

[Chris Kantarjiev]

I don't have a K2 (yet), but I have a fair bit of experience with
trying to cool computer cabinets. 

You can get a wide variety of 'box' fans, that vary greatly
in how much noise they make and how much air they draw. I'm 
very fond of the ones that Antec sells - they cost a little
more, but have a very good airflow/noise ratio.

One model that might be of interest to the K2 (and similar)
users is the SmartCool line

which has a builtin thermistor and varies the speed by the exhaust
air temperature. They are also offering a variant that has the
thermistor on a separate mount, so you could have it cool
based on the temperature of the final output stage.
