I have to say that I expected the fans to be "whisper quiet" from all the favorable posts I'd read before receiving my K3. My previous history is with rigs having external cooling fins and no fans, so I'm probably spoiled regarding fan noise. As much as I do love the K3, I hear the fans kick in when I have headphones on. This happens after a fairly short CW qso at 100w. The rig has been checked out at the factory, so I guess it re-affirms the notion that everyone's ears are different.
