I am getting a large humidor cabinet, like the Pienza they sell on here, and was wanting to add a small fan to the top of the unit to circulate the air and am putitng a cigar oasis plus on the bottom. I think the air needs to get up to the top though.

Anyways, has anyone ever added a small fan, like a computer fan and how did you connect it to the outlet?

thanks

I connected my computer fan to a 4-AA battery pack from Radio Shack. The fan ran for 3 straight days on the same batteries.

Search the forum for "Sketcha" and you will find the definitive humidor circulating fan.

You may have an old AC adapter just perfect sitting around the house. Look for an adapter whose output is 12V DC, the larger size the better. If, unlike me, you throw old junk away, look around at used electronics and computer shops. (Also check your computer fan's voltage, but it's probably 12 V DC.)

Cut off the adapter's plug, and splice the adapter wires to the fan wires. Test it, and if the fan runs backwards from the way you want, reverse the wires. If the adapter doesn't get HOT after a few minutes running, it's relatively safe. Insulate the splices with electrical tape.

Disclaimer: running this 24 hours is not recommended, since it hasn't been tested by Underwriters Laboratories, etc., and could conceivably start a fire, but you did ask. It would, however, be safe to plug it in a couple of times a day for a few minutes while you're standing there.

PS.

Some AC adapters put out low voltage AC. Make sure yours is 12V _DC_. It should be marked on the adapter.

Have been thinking about adding a fan to my humi. Checked with Radio Shack and they sell a laptop fan that is perfect in size but runs too fast (6500 rpm).

Thought of using a variable ac/dc/converter and run the fan on maybe 3 volts instead of 12 volts. Haven't tried it since the fellow at the store said that the fan might not even turn over at 3 volts. Just need the fan to turn slowly like a ceiling fan. Anyone with electrical knowledge have an idea?

I tried a 12V fan with 3V, two 1.5V batteries, and it wouldn't turn at all. Low torque, I guess. (YMMV, depending on the fan.)

What I would like to do is figure out how to have it turn on 2 or 4 times a day to stir the air, rather than run constantly.

plug it into a wall timer (used for turning a lamp on and off when you go on vacation). Set the timer to come on several minutes a day

Schmitty....that's exactly what I did. Set mine to run for one hour at a time, 5 times a day(24hrs). Using a pc fan with AC adaptor.
