Ok, I have a fan from my PC that came off the preocessor chip. It says its a
12vDC motor. Am I to understand i can splice this to an old cell phone
charger to power it? It has 3 wires, i would think the charger will have 2,
so what about wire #3?

Chaz,

The 3rd wire is an opportunity to get shocked!

Are you just moving air over one plant. A PC fan doesn't move much air?

Good Growing,
Gene

The third wire is a sending wire to send RPM information to the
computer. You cont need to worry about hooking it to anything.
Depending on the size of the fan it will move 10 - 50 cfm. Not a lot of
movement, but a couple are usually sufficient in an enclosed case to
keep the air flow up. If your plants are in a larger area that is open,
I'd suggest a bugger box type fan to keep the air moving.

OK,
the fan has a red, yellow, and black wire. Any idea which is the RPM?

Should be the yllow one.

Kye.
