When I received my factory built K3 last spring (#1001) I thought the fans were louder than I expected after reading about folks who had to physically check to see if there fans were on. I could hear the fans start up through my headphones when PA temp hit 37C. I sent the rig back and the good folks traded out a few other fan modules and reported that the noise level was the same and appropriate.
I inquired about Elecraft changing fan suppliers. They said that had happened, but the new supplier's fans were as quiet. So, I believe there are a variety of experiences. My fans are not whisper quiet, but maybe I, too, have been spoiled by my TT rigs with external cooling fins and no fans. Gary W7TEA I was trying to ferret out some weak signals on 160m when the cooling fans switched on, making it very hard to hear over the "whine" of the fans (or fan) even through the padding on my headphones. Has anyone tried to quiet them down with vibration isolators, etc?
