    Most cooling fans are 12 volts. You can get those universal power transformers (the 1.5, 3, 4.5, etc. volt ones) cheap, too.

    I assume you could just send the 12v fan a 6, 9 volt feed and it would run slow (but still work).

    Would this work? I want to play with some DIY cooling solutions.

    Thanks!

    Yes, that will work down to at least 7v for most 12v muffin fans. They're not quite the same as a typical electric motor, though. The magnetic pulses are electronically controlled as opposed to typical mechanical brush-contact motors. If you're just looking for some quiet 12v fans look for Panaflo L1A models or NMB 3110KL-04W-B10-P00.

    or just pick up a nice 120 mm fan and run it slower.
