[Elecraft] Some "Cool" heat sink info.

[Dave B]

You can also of course, use a minature 12V fan (CPU cooler type for example) to 
waft some extra air over either the back of an unmodified KX3, or any of the 
after market heatsinks if you need extra cooling, or the environment is 
somewhat warm.

Even a low speed (audiably quiet) fan will have a marked effect for the better, 
for minimal extra 12V current load.   Remember to decouple the motor, else you 
might hear fan related rumble or buzzing sounds in headphones etc.  (I've not 
tried this by the way, just sayin'.)
