Computer fan lower heat stress
well in a nug shell, those tiny comp fans have 2 wires, negative and positive. First you have to make sure that the charger voltage will support the fan in the first place. If it does [look at voltage on the charger and the fan, usually says it on it] then touch the positive to the positive on the battery and the negative to the negative and it should work. I didnt try it like this but ive tested with one of those batteries that go into a hand held camcorder and it worked like a charm [i dunno if that helps you tho].
**EDIT**
Your best bet is to find a battery supply from a computer and look at the links above that show you how to wire it up that way, VERY simple, i use the comp fan in my dryin room to keep currculation..SunnySativa Reviewed by SunnySativa on . Computer fan lower heat stress So i figured the tops of my plants where gettin way to much heat stress from the HPS lamp giving them life and i cant move them any lower or the light any higher so i figured i gotta extra computer fan and a 9Volt Battery, why not make a little exhaust fan to lower the heat stress. So i strapped a battery to the side of the fan, connected the wires and have it hanging right next the the lamp right between the tops of the plant and the lamp bulb. Its not super strong obviously but any help for Rating: 5
