I am trying to control a lot of fans, I am not at all interested in potentiometer fan controllers, PWM controllers, set voltage regulators, or anything other than what I am about to describe. Sorry for the long winded mini-rant...
Lots and lots of fans, but not anywhere near enough current provided by fan headers. These are only 3 pin fans, no PWM. I want to use the analog voltage of my built in fan controller to drive a linear regulator reference, giving me a lot more total wattage of fan control. I believe the best way to get this done is a simple linear voltage regulator, preferably a low dropout kind. I will only be using 12V from the ATX supply.
I have a few low dropout regulators I believe I can make work, but I'd rather have someone more experienced check my work for a fee. From some light research I think I can do it with a pair of diodes and some input/output filter capacitors. The regulators are BA00CC0WCP-V5E2CT-ND, I'd prefer to use these since I already have them. The data sheet can be found here...

Thanks for looking!
