Dayton sells small axil fan for electrical cabinet cooling... They are about 3x3 and are 120 volts.... Be careful with ones your not sure of the voltage. The Dayton axil fans can be wired to a cord with a plug and ran 24/7.....:thumbsup:

Wiring Computer Fans Hey guys, I'm working with a 8.5 cubic feet grow box and I need to add an exhaust fan to blow air from my grow box through about 2 feet of flexible ducting and then into my carbon filter. I found some good computer fans at a local store that move 100+ CFM and I was wondering if its possible to wire these directly to an extension cord without killing the fan? I've been lurking these forum for awhile and have seen a bunch of people using computer fans so I'm just wondering whats the best Rating: 5
