Would i be safe to run 3 fans (1 is on a speed control - 800RPM to 2400RPM) and my LED light on the the fourth. 1-3 Fans (1 variable) 4 - LED light (front panel) Thanks again. | Report abuse sirrobin4ever March 19, 2007 1:59:11 PM Should be absolutely fine. You can run pretty much as many fans on one circuit as you want. (Be sensible!) Fans are just about the lowest power draw component of your computer. Leds also use a very small amount of power. You'll be just fine.
