12v cooling fans

[ILIKECOUGARS]

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

[Doug]

Right on guys. Thanks

He allready SAID he had 2 25mA Fans So they are avail. My above post should have read 25mA not .25mA But that should be easy to figure out....

If you find the fans are too noisy you can run them in series which will give each fan 6v. I do this quite often with those PA fans as they do tend to be a little noisy at 12V.
