[Elecraft] K3 Noisy fans?

[W7TEA]

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.

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?
