This subject has been discussed before. There are apparently fans by different manufacturers used in the K3.
I'm fortunate ... the fans in mine (S/N 0056) are not audible, even during hours-long contesting events. They are absolutely silent. Yes, they -do- run ... I've seen 'em. (:-) If could read the make/model of mine through the grilles I'd provide the information, but I'd have to disconnect the K3 and disassemble the fan panel. 73!
