Fan Switch

[pigpottomus]

Hey all, Was just wondering if there are any sort of DIY guides/advice/help for fan switches? So you could turn the fan off or on. I have 2 switches, the one's that are on Power Supplies and a Flip switch(i think).

Thanks!

Cut the black wire of a fan and put the switch in between the wires.

Done.

If both fan wires are black, do the black one.


Actually, be best if you posted a pic. You could be talking about a 3 pin with RPM control or a 4 pin PWM.

No matter which one the ground (usually black) just needs a switch.

Forgot to say, but would it be able to do more than one fan per switch? maybe 2 or so?

A switch can usually deal with many amps. 10 maybe. So 20 fans is okay on one switch.

Voltage x watts = amps.

Ohms law. First day of electrical class.

Ah, ok, thanks for letting me know on that part. Got sick from school when class started on that topic.

Okay............... Sorry you got sick on the first day and had to drop the course.

The courses are usually a few months long.

Many college courses or on line basics electricity/electronics courses are out there.

I think you mean Watts / Volts = Amps. V*I=P; I=P/V.

Yep, oops. Been a long time.
