They look like computer fans, any .5A 12vdc adaptor will do

I use variable voltage type DC power supplies on my fans. It allows me to vary fan speed by dialing the voltage up or down like 6v, 7.5v, 9v, 10.5v and 12v. It cuts down on excess evaporation in winter months and lets you keep the tank at a more steady temperature without forcing the heater to come on.

The ones I use are from Harbor Freight Tools and were only $5 apiece but I have not seen them there lately but I have seen them at WalMart, Frys Electronics and Rdio Shack for $10-$15. One power supply should easily power up to 4 fans wired in parallel not series.

You can get 12 volt wall warts that will run them. You should be able to get that at your local Radio Shack and wire ends for connecting them. No big deal. Or you could look for 120 VAC fans from Jameco.com, like this one. https://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_1585371_-1

I have tried many many 120v AC fans over the last 30+ years in the hobby and every one was much louder than the DC variety, every one.
Several advantages of the DC fans is quieter, the ability to control speed by varying the voltage with the wall wart type adjustable DC power supply and the fact DC is safer around water.
I buy my fans from New Egg myself and have been the most happy with the Vantec Stealths, quiet and very dependable. I still have two of them that have been running for 9 years now.

I ended up buying the fan that I originally posted.

I also found this adapter in some spare supplies. Will I be able to use this adapter on the two fans?
