So i just bought a 3pin and 4 pin Antec TriCool 3 speed cooling fan for my new setup and am not quite sure how i would go about powering it... Any suggestions? I have an old computer i can salvage stuff from and i would like to not have to cut the cord on the fan unless i have to. any way i could hook it to USB? ive read that the fans are usually 12v and the usb is only 5. i would be hooking the usb up to a power strip through an iphone outlet usb thing most likely. Any suggestions!?
