Hi Brian, I'm sure others will chime in. What mode are you using? What power? What SWR? What's the room temperature?
At 100 Watts, for MARS I need to lecture on USB for 20 minutes at a time. No problem what so ever. With digital modes I do need to cut the power down to 50 Watts. I never hear the fans go on. I think you need to give us all the details. I would never dream of replacing the fans on the K3. Perhaps the temps need to be recalibrated. I just would hate for you to go though all that work if it wasn't truly necessary. It is such a well engineered radio. I'm sure Elecraft has the temperature management aspects covered.
