12v cooling fans

Doug · #1 06-29-2009, 12:22 AM

Can I run two 12v fans from one 12v/120 converter?

More than likely yes. You just have to check the current (amps) out put of the converter and then add up the current draw of the fans. That being said fans don't usually draw very much current, so you should be fine.

As long as your fans are 12 volts DC,

Yes, they are 12v DC fans. Your typical Princess auto fans. They say .25amps. Power supply is 120v AC 20w / 12v DC 12w.

Thanks

You need to know how many mA the power supply is. Fans are 250mA each so PS must be a minimum of 500 mA.

Should be able to run 4 of those then

Yup, can run 4 .25mA fans. If you want real power, get a old computer power supply. They can power a ton of fans. Plus, you have 12v and 5v and you can mix it to get 7v So, you can run a fan at 7v no problem, little slower, less flow but alot quieter

used to do that in my overclocked computers all the time.

In case anyone cares, to turn on a computer Pwr supply, connect the Green wire to ANY black one.
Yellow to Black 12Vdc
Red to Black 5Vdc
Yellow to red, 7Vdc

Don't let bandit confuse ya here Doug, you can run 4 250mA fans, don't go searching for .25mA fans, doubt they exist and you'd be able to run 4000 of em if they did

Right on guys. Thanks
