Computer case fan in humidor help

If you can find a variable voltage regulator, you can adjust the speed of the fan by varying the input voltage. Then, you can add a digital timer before the voltage regulator and have it come on for a few minutes at preset times!

I need to figure out how to do this... I have three fans in my tower that I can't turn on because they are just too damned powerful.

I believe you are looking to do something like this...... (different application though )

I apologize for the somewhat crude Iphone4 pictures.

We burn up a lot of routers, so here you have it, a super cooled router. I took an old CPU fan and a desktop humidor tray (don't worry the desktop is broken) and used it to mount a router.

The router is powered by a Radioshack 3V-12V. A couple wire splices and some hot glue to insure it stays...bingo job done, sure it ain't pretty but it works.



The Radio shack 3V-12V (it took all 12 Volts )

Make sure that the fans are able to run at variable speeds, first. Bill pointed out the radio shack option, which is pretty good, IMO. If you can find an electronics supply place near you, go in with the fans and explain what you want to do. They should have everything that you need.

A quick google says that these folks may be worth a call, Dan:
