Steve,

 

These are DC fans.  How are you using them?  

 

I always get AC 120VAC fans and wire them with a cut up extension cord, if they have no cord with them.

I use 12V DC fans from www.nexfan.com  They have misc sizes and various models that have varying dB and CFM ratings.  They carry Vantek Tornado's which handle quite a bit of air... but they are louder which is an unaviodable trade off I think.  Some also have thermal controls, just another source if people are looking for DC fans.

You can pick up a 12V DC supply from radioshack.  I had power supplies from my Icecap fan purchase as well (they are 12V DC as well).  I'm using one of the Icecap variables in my DIY ballast box to cool it.  Works well.

 

I already have 4 of the fans you listed.  2 are in my new hood.  2 are sitting on the shelf.

 

I was just posting as I thought they were rather cool as compared to price of Icecap.

Steve,

 

The DC fans are cheaper, move a lot of air and are quieter.  Will any 12v DC adapter work?  How do you setup temp control and all that?

To run a single fan at it's full potential pretty much any one will do.  I think the smallest I've seen is like a 12V/300mA supply and most DC fans do not exceed 200mA.  A 1A supply or 800mA would definitely do the trick for one... or a few more.
