I have this Fan and adapter but I have to set it to 9v to get fan to move then it spins up extremely fast and stops abruptly, but keeps spinning with the momentum before it spins up really fast again and again. Is there any way I can make this fan spin constantly, it has four wires red,black,white,blue. I thought maybe I could use it to connect to a homemade scrubber for a small stealth grow, plus I'd like to know if homemade scrubbers actually work and don't just look good in the pics? Any help much appreciated.
