[Elecraft] Silent power supply for a K3s

[Gary Johnson]

I've installed modern, silent fans in nearly every piece of equipment  I 
own, including my Samlex 1235. They're not expensive and come in all 
standard sizes. Can't hear my PC or power supply fans at all from a few 
feet away. Look for Nanoxia Deep Silence fans. (No, I'm not retrofitting 
my Elecraft gear...)
