silent fans

My computer has the loudest fans ever.
need help replacing as much fans as i can to much softer ones-

There's a fan on the top of the case which blows outwards
There's a fan on the back which blows in
and a fan on the side that blows in. (this one lights up)

and ofcourse theres the psu fan, cpu fan, and videocard fan.

all that combined is one f***** loud *** computer

will switching to silent ones even make a difference?

component's that makes loud noises

PSU
CPU Fan
Video card Fan
Too many case fans
Case

if u want to figure out which ones that makes more noises, turn on ur computer wid all case fans unplug. if it's still noisy, then either the CPU fan, Video fan, or PSU.

get a fan controller
