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

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.

Thanks Steve. May try that. Will they then run slower also?

Yes they will run at approx half speed.

Gettin closer, 250mA, not 25mA still a huge difference. And I still doubt 25mA 12v fans can be had. Don't get upset, wrong information can lead people on wild goose chases to find stuff that don't exist, or won't work.

In Dougs case, we are talkin about a 12vdc 1a supply with 2 250mA loads. The supply is more then enough to handle the load.

Don't let your feelings get so hurt when information is corrected mate.

If you are looking for quiet 12v fans I found some fantastic ones at Memmory Express, they had some as quiet as 7.8 db.

They say 0.25 A. Whatever that is.
