forget the computer fans and go with one of these. more CFM, run on 110, can be hooked up to a speed controle easy.

If you want to ghetto up a PC fan, just get an old AC adapter that's rated anywhere from 7-14VDC and wire it up. The higher the voltage, the higher the fan RPMs (and thus noise), but they all work adequately. I've used a couple of old cel phone chargers to test them out.
If you need AC adapters, try Princess Auto (www.princessauto.com)

Holy! that really would be getto rigged! :razz:

I get 120mm fans from my work that are AC with a wall plug. They work great and no rewiring. My canopy has spots for 4 of them but i only use two at the moment. that might change as summer comes in. They are prey cheap if i remember right. about $25 or so

hrmmm...

the real question is.. do you have the fans suck the hot air out, push cold air in or have them in alternate positions?

Well as i have a window right behind my tank i will have one blowing in at each end and duct to the window with one blowing out. That way the heat goes right outside with any water in the air. That is IF the wife stays out from behind the tank long enough for me to do it without her knowing :)

then i can say "look babe now the heat goes right outside!!!" much better than "hey love you mind if i drop another wack of $$$ on the tank so i can removed heat?"

The big ? is where do you work and can we buy these fans I put a fan under my stand blowing on my sump and it seems to be holding at around 80-82

I work for a computer company and yes i can get them for you no problem.

Coool I may need to set up some fans to remove the hot air from between the light and the top of the tank how big are they I think you said 120 mm and one more ?do you know what RPM they run at

I can just get the 120's will check on RPM's next time a place an order from that distro
