[Elecraft] K3: Noisy Fans

[David Ferrington, M0XDF]

double check the fan wires that run between the fan casing and the  
back panel - it might not be possible to see those from the top and  
you would need to remove the fans from the back panel.
But you might be able to tell by slowly rotating the fan manually, if  
it was a wire, you might be able to feel/hear it as the blade goes  
past. You would also be able to feel the bearings if they are that  
noisy.
