I'm planning to do a similar setup
Not sure in power sources yet myself,
I have many of these fans and some quite big (>4")
I plan to attach carbon filters to remove smell
vampyreatdawn Reviewed by vampyreatdawn on . PC FANS! I took the fan out of an old pc and I want to use it for my fan system. It plugs into the mother board and I dont understand how the hell Im supposed to get it to work...I cant have this big ass mother board hanging out of my grow box so im sure someone knows how to do it. THANKS! Rating: 5
