How do i wire a pc fan to work

[Guest]

hi i'm in the middle of building my grow space, i have a small pc fan with two wires on it but am not sure how and what to wire it to.... any help please.

you have to strip the wire on a 12v dc adapter and connect the wires from your fan to the ones on the adapter and plug in the adapter.

Hi there, If you take a look at my thread
http://www.icmag.com/ic/showthread.php?t=18478&page=6&pp=15

You'll see i wired 4 Pc fans together, for the power i used an old Mobile phone charger
(12V)...then just used those plastic blocks (for wiriing car stereos) or u could use scotch blocks i think they are called....

maybe even with a switch might help

Hope this helps

If you have any AT power supplies They work the best. Multiple lines good current output.

computer power supply. But yeah just take a convertor(those big boxy plug things) and read it. Kepping on reading as much as you can until you find a 12v output one. Now cut the end off so you have a long wire attached to the plug. The red wire on your fan connects to the wire on the converter with a stripe. then connect the remaining 2 wires together. If done right your fan will spin, if not you just burnt out the motor. These fans usually only work 1 way.

is wiring the fan to phone charger safe??/???//.... dont sound it any one else tell me?......

Yep, it's safe, as long as you're not silly about it. Wire nuts, and don't play with wires that are plugged in

is wiring the fan to phone charger safe??/???//.... dont sound it any one else tell me?......

well that depends on the charger
some phones use low voltage like 4 - 5v and a low amp rating (few hundred Ma)
others are 12 - 14v and sometimes over 1a output
the latter are Ok to run the fan's from a PC as they require 12v and about 500Ma - 1a to run depending on the model

I recommend an old AT or ATX power supply from a PC though as it has the correct output
and are built to run for long period's
phone adapters get very hot and are a possible fire hazard if there running higher
than there designed use

better safe than sorry

yes you can use a phone charger or a AT or ATX power supply but keep in mind that if you use a power supply from a computer(AT/ATX) that you most likely have to keep it in your grow cab thus raising the temps in your cab and as many of us have found out the heat from the light can be hard enough to deal with never mind adding more heat to the cab. If you are going to use a cell phone charger make sure that both the fan and the charger are rated for the same volts, also like GotTheBlues said when wiring your fan red fan wire connects to black with white stripe charger wire if done wrong better head down to radio shack and buy another fan.

If you dont want to spend all that juice on one little fan then pickup one of these @ radio shack. This one will run a few fans for $17

What does your fan have on it ?

adapter should have
Something like input 120 vac,,,,output dc 12v
240vac alot for dc12v





.

 

[GeD]

i just blew a dc 12v 0.45 amp, and now got a dc 12v 2.0w,if i use a 300psu will it use all of the 300w power why its on all just the 12v of power i want

[FONT=Arial, Helvetica, sans-serif]Output : DC 12V 1000ma[/FONT]
this ok?

 

[GeD]

ahem ^^^ noone no?

 

[I N Hail]

[FONT=Arial, Helvetica, sans-serif]Input : [/FONT][FONT=Arial, Helvetica, sans-serif]Universal AC 100-240V[/FONT]
[FONT=Arial, Helvetica, sans-serif]Output : DC 12V 1000ma[/FONT]
this ok?

The adapter you need will have to have the same on it ,the amp(1000ma)
can be higher.
The adapter must be 240v input dc 12v output

thats why the other one burned out it was for 120 input

Use the 300 it will only use the amount of power the fan needs when running
