Pushbutton 7v/12v fan speed controller

[whrswoldo]

Instead of a common toggle switch or rheostat I decided to use a PushOn/PushOn switch to alternate between 12v and 7v for my fans. Basically, you push the button to switch between modes. I didn't see this in the FAQ so I thought I'd share. Here's a leet paint drawing of the circuit:

To mount the switches I carefully (with pliers) removed the front port mic and headphone connectors as well as the firewire port connector for good measure (my mobo doesn't even support firewire and X-Fi cards don't work with front audio connections...).

Anyways here it is, ignore the dust:

The other switch is just an On/Off switch for UV lights.

That's sick. Where do you get these switches?

I found them at Fry's locally.

What about "off"

What about "off"

Turning the PC "off" takes care of that. A PC "on" with fans "off" option would probably be a bad thing.

What about "off"

Considering the fans are indirectly cooling my CPU core, GPU core, and NB, I think I could just as accurately label that switch position "release magic smoke"

I guess off would be a bad idea then huh...

I sometimes run my computer with only the PSU fans on for a few hours at a time... before the cpu temps get too high. Water has such a high heat capacity...

Ooh. I like that idea (removing ports that aren't being used.)

I was looking for a place on my Antec 900 to mount my toggle switches.

use those two spots and mount the sideways r straight forward which ever way works..

Very nice idea. I especially like the way you tore out crap you weren't using. After recently cramming a WC system into a V1000 and having it turn out pretty fugly, I have a real respect for making the most out of the space you have.

Another thing you can do if you don't want to use a toggle switch is use a DPST relay and use any switch you want to actuate the relay. That's how im using my ever so pretty black (w/ blue led) rocker switches to 12v/7v my panaflo's.
