help wiring a fan

[Timothy01]

i am going to wire a couple fans( computer cooling fans from comp usa) into my hood. need some help with the wiring can i splice these directly into my lights or do they need a diffrent power source.

They need a different power source.
Computer fans run on 12v DC. You need an AC/DC 12v adapter or a cheap/not-in-use computer power supply.

The fans should say on them what voltage they require. You would nee a transfomer to match this voltage.

They should also specify what amperage they draw. You add the amps together, then buy a transformer rated for at least that much.

thanx so something like an old cell phone charger would work rated 12 dc ...correct

 

[CKreef]

if amps are okay but most phone chargers arent enough

 

[Timothy01]

yeah i have a ton of adapters just went through only one 12v need to go buy another one raido shack here i come

You don't need two transformers for two fans, unless you want to control them independantly. Just add the amps together on the fans and get a transformer rated for at least that amount.

all i get on the packaging and the website is 12v dc

If you buy AC fans, you can wire them with your lights. I have two Muffin fans wired in line with my actinics.

Here is a link to the thread I posted.

Can you post a link to the web page where you bought them and/or post a picture of the writing on the fans?
