I too am annoyed by ambient noise, especially fans.. ALL fans make noise, some 
just less than others.. Once you have your other ambient noise sources quieted 
down enough in the shack then the 5K's fan is very noticeable. Here's my tale...

After building a new house and of course a new shack space (it uses up about 
1/3 of the basement). One requirement was to make the new shack be as quiet as 
possible. And also to make the equipment be easily accessible, both front *and* 
back.

So for the 16' long equipment wall I used shelving that attaches to a wall. But 
the "wall" that it is attached to is essentially just 2x6 studs that the shelf 
support rails are screwed into. The spaces between the studs is completely open 
for easy backside access to all of the equipment located on all the shelves.

So to control the noise sources I hung sound barrier curtains about 2+ feet 
beyond the open equipment wall. That leaves a about a 2 foot wide alley to get 
access to the equipment backsides. So everything that makes noise goes on the 
other side of that sound barrier wall from the operating area on some rather 
industrial strength free standing shelves (4 levels 30"x72"). This shelf unit 
is perpendicular to the equipment/sound barrier walls, so it has both front and 
back side easy access as well. So basically all of the items that have fans in 
them, including the 5K is put on those shelves. So the "noisy" side of the 
sound barrier curtain I consider to be my "equipment room", it also has the 
furnace an few other household "equipment" in there as well. The KVM and 
various other control/support cables are then routed through the sound barrier 
wall to the monitors and all the other no-fan radios/equipment sitting on the 
shelves in the "operator's space". To
 further suppress sound in the equipment room I've hung some strategically 
placed sound absorbing panels to reduce the sound level that the barrier panels 
have to deal with.

I still have some ways to go to further suppress the noise sources, but it is 
already pretty good. As I was increasing the level of sound suppression I'd 
find more and more items that I did not previously notice as being noise 
producers, and they soon became irritatingly obvious. The 5K was one of them, 
so it (along with its "blue death ray" LED) got banished to the "equipment 
room", I can now only hear its relays click as I change bands.

The operator's space is now quiet enough that I now notice the white noise hiss 
from some of my powered speakers.  Most of my linear power supplies are 
abundantly obvious sources of noise now too (still thinking about how those 
will get moved to the equipment room too). I'm even being irritated by one of 
the CCFL LCD monitor back-light ballasts in one of my monitors. I have two 
identical monitors, one makes very little noise, the other is a lot noisier... 
Maybe some LED back lit monitors will eventually fix that.

Suppressing the other household noises is now increasingly front and center for 
what needs attention. Things like lagging the heating ducts and to do something 
more with the basement ceiling..

So I'm enjoying my fairly quiet shack. Reminds of my early days in ham radio 
when I didn't have much equipment at all, not to mention any equipment that 
could even make fan noise :)..

I am not really concerned about a mike picking up the fan, I am concerned about 
me being bugged by it. I do not even like the fan on my computer. I never heard 
a fan on the 5000. It has a fan?
