Setting LEDs on case fans to turn off

post #1 of 5
Thread Starter 
Good afternoon!

Has anyone connected the LEDs off a fan that has them installed and was able to connect them to a switch somewhere in the case?

I have Five fans that have 3 LEDs on each of them and i was wanting to connect them to the switch along with my cold cathodes built into my HAF 922. I was wondering if that would be too hard since i have located the switch wiring etc. Just wondering if its at all possible and if anyone has done it that might be able to point me in the right direction.

Usually the LEDs are on the same power as the fan itself, so the only way to turn them on/off is to do the same to the fans. The NZXT 200mm fans come with a switch, but I don't know of any others.

Would it be ok to disconnect them and some how connect them to a power source directly?

Ideally i would like to rig up my fans that are listed to the case switch, could i splice the LEDS into their own wiring?

Yes you can splice the LEDs to their own wiring, as they run off of 12v. Just use the positive and negative of a molex connector (negative is usually black). If you got it wrong, just flip it around, LEDs will only work one way.
