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...

If this is something you are interested in please let me know via PM. Please also let me know what you think fair compensation would be for this work as well.

Thanks for looking!
