[Elecraft] K3 Noisy fans?

[David Ferrington, M0XDF]

The fans are whisper quiet on the K3, if yours aren’t there is  
something wrong - possibly as suggested by Stewart below, a wire  
touching the hub or the blades, or possibly a missing washer causing  
distortion to the fan casing.
Mine just don't come on and I have to use the CONFIG menu entry to get  
them to spin so I can check them.
