I have a little 40mm DC 12v brushless fan, would that work?
Thanks.

^^^^^^Anyone?^^^^^^

yes it will, but it will run slow on 6v....basicly at half speed, if you can get a 40mm 5vdc fan and run it at 6v....it will push more air....makes sense

From experience with 12v computer fans, 7v is pretty much the lowest voltage to use. Otherwise, the fan speed is so low that it doesn't really push much air. It'll work, but the results won't be great. Those little fans don't have a lot of CFM to begin with and rely on speed to get the flow...

It's all coming to me now.
Thanks guys.

good, glad to help....

Sjcrss, where do you get your 5v 40mm fans from. Can't seem to find them anywhere.
Thanks.
