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.

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

Ummmm...I have had a couple power supplies were you have had to take the green to ground to make them turn on!!!!

Now that its been running the duel fans, I notice the power supply is fairly warm to the touch. How much would be normal? Cant say as I ever noticed it before when running a single.
Thanks

It should be fine, Doug. Power supply's can get warm, as long as its not HOT. If you can hold it, its ok. They usually are designed to burn out before they cause a fire or anything anyways
