Hey ive decided to give my soon to be grow room pc a re haul, and i would like to add more fans from other old pc's i have. I have alot of phone chargers too, and I read that you could wire a phone charge to a computer fan and it would work, so i gave it a try and it does work. Would i be able to wire several fans together without hazard? Or sould i have 1 fan per phone cord? thanks alot.
