Default LED Fans

Just a quick question. I'm building my PC, and my case comes with some LED fans. Theres a side window on the case though. I'm going to have in my room, and i like to keep my computer on most of the time. so i was wondering if theres any type of a switch you can make or buy to just turn the LED's on at a specific time without shutting off the computer.

HaHa!!! That's funny since my computer's been down for two nights and i couldnt get to sleep without hearing it. It was too quiet in my room.

Adam - Most fans with leds on them are contolled by one line of power in so unless there is a seperate power source for the LEDs (two hot wires into the fan) and a way to put a switch on that second line then there's no way to put a switch. Although with some fan controllers you can turn the whole fan off which in some cases (mine) would be bad for cooling.

i think that it is possible, on my Akasa 120mm blue LED fan there is a yellow strip of paper-rubber-stuff under that there is what looks like two sepatate cables for the LEDs.
cut one of thes,peel away from the one next to it, strip the insulation, find a push button switch, solder, tape with insulating tap, done.

all of this seems a little much but the result should be exactly what you want ,(i think).

of course it's possible. A simple switch between the power and fans is all it takes. That's a breeze. get a cool lookin switch from your local o'reilly's or autozone, or what have you.

I like KMOTE's plan. But Ryan, putting a switch between the power and the fan would turn off the fan, which i dont want. haha. Just the light.

So yeah, I might give it a go, its not like fans are super expensive anyways.
