Fan Switch

[BadImpact]

Hey Guys, I am building a new desk and I am having a part for my Xbox to slot in to the desk. I would need very good airflow so I am thinking of hooking up fans to help push the air through the chamber to the large exhaust point At the back of the custom build desk.

I will be running 3 Pin fans of a 240 watt power supply of my Older PC. I was wondering if i would be able to add a switch to turn off the fans when not needed. The link below takes you to the switch...

Can someone please explain to me how to connect the switch to the fan and maybe Include a link or such.

Thanks Guys!!

Have you thought about using one of these.

You could then use a molex extension cable from your PSU and just cut the yellow wire and put the switch in there.

If your psu is not attached to a motherboard then you will have to jump start it. Paper clipping the green wire to any of the black wires will do it, or buy one of these.

Scan sell a (24 Pin) ATX-bridging plug.

Yes But What would I do then when i connect the yellow to the switch (sorry i sound like a noob. I don't have any experience in this kind of thing)

You cut the yellow wire on the molex extension cable and solder each end of the cut wire onto the switch. The yellow wire is the 12V live cable - you always wire a switch to the live wire.

Okay. Thanks. What prong(s) of the switch do i solder the wires on?

Thanks!

If you look at the Q&A for the switch it says:-

"Q)Connecting the ''Power'' tag to +12V and the ''VCC'' to the load does not let the LED light up when the switch is ON (although the load does operate). Does the ''Ground'' tag need to be earthed for the LED to work?

A) Yes the ground does need to be connected."

So you can connect the Power Leg to the +12V yellow from the psu, the other yellow to the vcc leg and the ground leg to the black wire nearest to the yellow wire. You don't have to cut the black wire just strip about a 1cm of insulation off it and solder the wire to it. Then you can use insulation tape or shrink rap to make sure you don't short anything out.

Like this:



This is so that the led will get 12V and light up when the switch is on.
