LED lighting in an old system Tags: Homebuilt Fan LED Monitor Systems Last response: June 14, 2012 5:11 PM in Systems Share DarkBowser June 13, 2012 6:04:28 PM USB is 5 volts, and that is too much electricity to power custom stuff that I made. I want the electricity to go to the fan first. Should I hook up the fan to the battery and then the LEDs to the fan?

I half got it working right now, I just want to do away with the wires m 0 l Related resources any good rgb led lighting systems with remote for pc? - Forum 10 month old system does not boot(yes fans, no power led, no beep) - Forum Motherboard led not lighting - Forum Led lighting for pc case - Forum num lock LED not lighting up please help - Forum Can't find your answer ?

The fan reduces the voltage to just about what I wanted. That was my initial plan, and my original question was about putting the resistor in series or parallel. m 0 l FinneousPJ a b B Homebuilt system June 14, 2012 3:50:11 AM Cool, hope it works now. m 0 l DarkBowser June 14, 2012 5:11:11 PM Yup, now I need to buy more LEDs. m 0 l Can't find your answer ?
