Is it possible that some are noisy little err things and some are not? I 
have mine running all the time at LO (very quiet) when my KPA100 is on, and 
so far it has not switched itself to HI (noisy) even during a contest. Shack 
ambient temperature is usually about 65 F. The heatsink gets warm but not 
hot.
