Wiring Computer Fan(s) to Run on 120V A/C
Posted 10 April 2009 - 04:39 PM
as well as burning from 300-600 watts to power your two fans!
doubt it, unless you have something to use that power, where would it go? maybe if you had a computer with hard drives, motherboard, CPU etc. to power, but if you only have two small fans, they're only going to use the power to turn the small fans

i thougth it was wierd but i dunno, i like the radioshack route better unless you have a junk power unit lying around (which i do wait a sec, need to think that one over)
In a pinch, you can buy a 3 pack of 6V batteries at walmart for 4 bucks and power them for almost a week per battery, depending on the voltage of the fan

indeed. that's really what I meant, if you have one lyin around it's a free power source and you can hook plenty of fans up to one quite easily. of course it's always better to use something specifically made just for the fans

Also, it is worth noting that an AC adapter will put out its specified voltage at full load. If operating at less than full load, there is a good chance you are getting extra voltage. Use a multimeter to see how much exact voltage you are delivering to your fan and make any necessary adjustments accordingly.

Wall warts come in a variety of sizes. I have one that is rated for 3A @ 12V. Always hang on to these when tossing old electronics. If you're looking for some, hit up your local goodwill. They seem to have a bin of these by the electronics. Can be had on the cheap.
