rottface4 Posted September 15, 2005 Author Share Posted September 15, 2005 I have 72 LEDS in my array, and I have two 9 watt PCs. I keep it cool with a fan in the back blowing the hot air out of the hood. I have a 12 v 1 amp power supply for both the LEDs and the fan. It is a little under powered though. The fan draws .23 amps, and the array draws about .9 amps. Link to comment
