I stand corrected. There are apparently a lot of quiet K3s out there.
I wonder if the quiet fans are from a different manufacturer?
The fans in my K3 are made by UTEC:
Series 8162 P/N AT6015L-12L2B ND5
Series 8163 P/N AT6015L-12L2B ND2
The replacement fans (from Elecraft) were identical.

around and looking at them.
That's how mine are too (S/N 10 - early pre-production K3) and I am
very
sensitive to fan noise. On the rare occasions my K3 is actually
assembled an
on the operating desk, it's close to a wood paneled wall and I'm not
aware
of them even though there's not a single other fan our source of
noise in
the room.
Indeed, I sometimes can't hear them running when I'm working on the
rig on
the bench.
After taking a number of complaints about the little "whizzer" fan
in the
K2/100, I believe that was Wayne's intent ;-)
It sure sounds like something is quite different now. I'd recommend
also
posting a note on [EMAIL PROTECTED] about it.

I think you got lucky and have extra quiet fans :-)

That's how my K3 is set up too, in a corner where walls can reflect
any noise.
I still think there is something else wrong.

I've also found that where I place the K3 on my desk makes a
difference in how loud the fans sound. My desk is in a corner of
the room and if I place the K3 so the back is pointing into the
corner, the walls reflect any sound right back toward me and the
fans are louder. If I place it on a table in the middle of the
room, I don't notice the noise nearly as much.
