You might want to check your current fan model(speed and
noise level) and compare with others.
You might be able to find same or faster speed(and more air-flow)
with less noise level.
But I won't go with slower speed.

Also, if you are using exact same hardware and PC is less noisy,
fan might have speed control with temperature sensor, and just
PC is not working as hard as Linux to produce load/heat.

Linux doesn't make fan any noisier than PC or the other way around.
