I'm Tom and I own towercooler.com. A 12 VDC power supply will work fine and we use 12 VDC power supplies with the tower coolers we build & sell today. Our first tower coolers blew too much air with a 12 VDC power supply but we have found a fan that does not move as much air and this allows us to ship today's tower coolers with the same power supplies we use with our stir plates.
Also, a 100 ma power supply will be more than enough - even 50 ma rated power supply will be enough. Small PC cooling fans draw very little current, typically less than 30 ma.
