Help with wiring fan speed controller to....well, a fan

[sidewinda]

could anyone help me with the wiring of a fan speed controller..... first the fan has three wires..red, yellow n black.

The fan controller has 2 sets of wire..... the first set consists of two wires (yellow n black).

The other set has three wires...red yellow and black

I have tried connecting the 3 fan wires...to the 3 wirs on the controller, then the set of 2 wires to power,,,the fan then runs at normal speed with no control....

....grrr. I been waiting for my controller for a month, its now turned up and ive tried to find out but am just reading how people have burned them out...

....so i thought i better ask

....thanks in advance for any help

One of those 3 wires in the 3 wire sets is a ground wire the others are positive and negative. Find the ground and just tack that wire to a bolt or something and the rest tie them with the other two and you should be ok. (USUALLY, the yellow one is the ground). Proceed with caution though. I would wait for a already made controller. You don't want to cause a fire and attract more attention than you need to.

Thank you for the reply Awnox,,, your reply has done it for me... this cost me next to nothing anyway.. and your right, its not worth it. Its just i need to put a carbon filter in for flowering soon, and i thought it would help the speed... same old eh, pay penuts, get monkeys, do you know of a good 12v inline 3 inch fan.. im playing with pc fans...maby 2 of them together...would you say im probably wasting my time with it? Thank you again for the help.

ive use a 3 inch ducting pipe as it was just laying around and i thought if i could mount some high cfm pc fans together it will be ok to adjust with a speed controller to vary the speed to adjust the air flow withing the carbon filter. But ive had a rethink...stop being bodge and get a proper inline..id have to maby use a reducer, cos it took me ages to stealth the all ducting to alow fresh air in at the bottom.( I will check that fan out navyfighter.....right now) thanx for all the help..

....together, we shall win
