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?

DarkBowser June 13, 2012 7:19:41 PM The same power from the power supply is also 5 volts, so I'm stuck. I half got it working right now, I just want to do away with the wires Related resources Suggestions required for LED Lighting in Corsair Obsidian 650D - Forum System won't boot or send signal to monitor\ led lights\keyboard\mouse - Forum CPU Red Led Light - Forum Fans spin, LED lights up for half a second, then nothing. - Forum New system won't boot.

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. FinneousPJ a b B Homebuilt system June 14, 2012 3:50:11 AM Cool, hope it works now. DarkBowser June 14, 2012 5:11:11 PM Yup, now I need to buy more LEDs. Can't find your answer ? Ask !
