(adsbygoogle = window.adsbygoogle || []).push({}); OK so im making a custom laptop cooler with 2 or 3 fans. I got 120mm fans with colored LEDs for style. could a 10V 1200 mA power adapter or whatever it is power that well or will i need more power? If it can only do 2 thats fine. No i dont got any info on the fans other than they spin at about 1700 rpm and have 4 lights.
