i need to fit another case fan to my system but not sure how i connect it - is it to the motherboard or to the power supply?i have spare powersupply fan, system fan and chipset fan headers on the motherboard according to manual, all at +12v. my existing case fan seems to be connected direct to the power supply but i cant tell as all the wires are in a huge bundle and i dont really want to take them apart if at all possible. the cpu fan is cnnected to the mobo. i was thinking about getting one with a L.E.D. on it, because i am pretentious. would this make it more complicated?
