Cape and Ray write – “LED fans are an easy way to add color to your rig, but mine are missing something crucial, a light switch. I’ve got four 120mm blue light up fans and they move some serious air. Their LEDs are pretty bright and have no problem illuminating my room a fair amount. Putting a small light switch on the LED’s lets me turn the lights off so I can sleep and keep the fans running for my hard drives. “ – Link.
