Can I use a PWM fan controller as LED dimmer?

post #1 of 4
Thread Starter 
I want to light up my case but I also want to control the lights too. LEDs apparently respond well to PWM signals, so I was wondering if I could use a PWM fan controller to control the brightness of the LEDs? I think it'll work. Has anyone tried it?

iirc leds on a fan will not go down with PWM control,

you can control leds normally tho iirc

It's not the fan LEDs I want to dim (they will be on a switch) it's the case lighting I'd like to dim.

I've wondered about this myself, but haven't yet tested it. I've put led's on a fan controller before and had some success, but I haven't tried the PWM yet. If it works, it would be a cool effect. As the system gets warmer, the case lights get brighter! Or they may go into a slow pulsing effect . . . cool!

Once I get further in my build I'll be testing it out. If you beat me to it, let us know how it goes.
