[Elecraft] K3 noisy fan?

[Stephen Prior]

Ron and others

Thanks.  I've identified the fan, it's the one with the short lead.  It's
definitely noisier than the other, and it's not an air type noise of the
sound that comes from the blades contacting anything, it just sounds like
bearings to me.  I'll email support.  It's not a show stopper.

Thanks all
