i have 3 fans. all wired to switches that i made on the front.

only one fan is turned on pretty much ever. i have a case similar to jonbos, and it has another switch to glow blue.
but ya dont need that many fans, the blue lights put out little to no heat.

i have one fan on the back that blows air out. then theres only the power supply fan and the processor fan.

*edit* suppose some might need more fans dependong on the processors. some AMD processors run hotter then a Pentium usually will. but still, that many fans usually isnt needed.
