so today my sister threw out her old computer i grabbed the fans out of it. how do i wire it one has 4 wires black, yellow,blue,red the other black, red, blue which are hot and ground i figure i'll use a vex type battery. now the stupid part i take it you use these to blow hot air down does this work i figured i would attach a clamp to the fan some how. for use in my hub thanks for any help

Red pos, black neg.

Blue and yellow are for variable speed and fan status reporting.

Typically.

A fan does help move the warm air around and also decreases condensation from propane combustion.

Great Idea, I will be doing this as well!

I picked up a 12 volt 20" ceiling fan that breaks down into a small 4x4x12 box for $17 at fleet - I'm not even bothering with the computer fan anymore.

I ordered 3 small computer fans last week for my spearhouse. I almost went with that mini ceiling fan but figured the movement over the hole would spook fish. How long does a vex battery last running a computer fan?
