A 4x4 or more correctly, a 120x 120 mm fan is more likely to
be a case fan. A CPU fan is designed to fit certain
processors and motherboards.
You can install fans with thermocouples that will adjust
their speed depending on the temperature.
Your computer will have fans in the power supply (one or
two), on the CPU, perhaps on the video card and one or more
to move air out of the case.
Air flow should go in the case at the front/bottom and exit
at the rear top.
The only way to tell if your air flow is correct and not
leaving "hot spots" is too put a sheet of clear plastic in
place of the case panel so you can see the air flow pattern.
The with the computer running a smoke stick is held at the
air vents and you watch to see that the smoke is drawn
quickly through the computer and does not have any eddy
currents (dead spots). Adding baffles to direct air flow or
additional fans in the right place will allow the best
cooling.
You want fans that move the most air at the lowest RPM. You
also need fans that are designed with quality bearings and
blades shaped for best operation. Cheap and quiet are NOT
impossible but you will have to work to find them.

If you want real quiet, try water-cooling.
| I'm looking to purchase a quieter fan for my CPU. If
anyone can recommend a
| cheap but quiet fan that'd be great. I have a Dell 8250.
My fan is 4" x 4"
| and makes a considerable amount of noise. I don't think
there's anything
| wrong with the fan it just is too loud.
