If you are trying to make use
of a PC case fan, but finding it gets quite loud, this is
for you!
You will need the following:
o Insulation foam strip (any thin foam should do)
o Heat-shrink tubing (from any electronics shop)
Step 1 - Preparing your mounting screws
Take your heat-shrink tubing and cut 4 pieces - each
around the width of your fan mounting (Picture 2). Insert
the screw into the tubing and shrink to fit (Picture
3).
You now have rubber coated screws to dampen some of the
vibrations.
Step 2 - Mounting the fan
Take your foam
tape, peel off the backing and place along the edge of
your fan (the side facing the wall). Make SURE that all
sides are covered!
As you can see, overlapping the tape is fine.
Screw the fan to your box wall tightly! The foam will
compress leaving an air-tight seal around the edge of the
fan.
The rubber screws
coupled with the foam seal will stop vibrations from the
fan, leaving only the sound of air passing through it.
This can be reduced to silence by running the fan at 9
volts!

A much simpler approach is using one of those camping
mats made of polyurethane. Cut a strip of the mat thatӳ
long enough to run 3 times around the outer sides of the
fan.
Make an opening for the fan that is slightly smaller than
the fan with the mat, OR depending on your setting, make
an frame for the mat/fan combo that you can fit on the
inlet/outlet hole (out of wood or whatever).
Stuff/slip/slide carefully the fan - mat combo into the
opening - simultaneously insulating any light and air
leaks AND very effectively sound dampening the fan. Itӳ
also possible to run wires through between the mat layers
as it flexes to accommodate wiring.
Usually its possible just to make the opening and slip in
the fan-mat combo, no screws etc needed. If the strip of
mat extends in front and back of the fan, the sound of
the fan (blades) and air rushing is also dampened.

If mounting and noise are an issue, another great damper
is silicone. If your fans are not near a direct heat
source (unaffected by high temp silicone mixtures), you
can effectively run a bead around all contact surfaces
prior to tightening...Silicone maintains a certain
elasticity after curing. Allows vibration to dissipate
and holds screws tight.
