Need advice on the wiring of these fans?

[WeedKillsBrainCells]

Well I dont mind particularly tearing this apart as cutting cables makes me sad but I was just wondering what im supposed to do as it looks like theyve been split? I was gonna just hook up a phone charge to the main cable, but what if I wanted to seperate the fans? 2 for exhaust one for intake (small grow)



most boring duvet ever

You have to hook them up in sequence. Get a 12v ac adapter (you might have an old one from a phone or something or go to radio shack), strip the wires, and run it like this. Black wire from plug to grey wire on fan a. Gray fan a to white fan b. Gray fan b to white fan C. Gray fan c to red from plug. Get some extra wire if needed, and aim them accordingly.

I may be crazy yet how would you use two fans for a single intake without stacking them in some such way? The wires should be marked regardless in some such way giving off the negative and positive.

Also, theres is no need for a powered intake. A passive intake is perfect as long as you have the hole for the intake cur to size and not overkill.

How big is the box/cab?

just to what cranker said its the best way by far

2 fans adjacent at the bottom one at the top on the other side

Those should be wired in paralell not in series like Cranker said unless the phone charger is 36 volts D.C.
Those fans are 12v and you should put all the red wires together and all the black wires together then to the phone charger (which is around 12 volts DC)

green squares are wire nutts

not hard to figure out which wire is positive and negative....just hook it up, plug it in and if it works you have it right...if you plug it in and it doesnt do anything, you have it hook up backwards, un plug it, swap connections and try again

once you figure out which is positive and negative the rest is cake

EDIT: DO NOT HOOK THIS UP TO A WALL OUTLET. Those are DC fans and as such will need a power supply to change the AC from your wall outlet to DC for use in the fan

ALSO: I may be wrong about it not working if hooked up backwards, it might cause the fan to run in reverse, so youll want to make sure the air flow is in the correct directions as well

How about 1 in 1 out 1 blowing the canopy? Most PCs Exhaust the power supply top rear and center rear and front bottom intake. Depends on case. 1 ball bearing means fan should be non reversable
