Mid-range Liquid Cooling, Automated radiator fan control.

I'm looking at putting together a mid range water cooling system for an upcoming build.

My question is this:

I would like the speed of the radiator fans (and possibly some case fans) to be controlled automatically based on temperature, In this case the temperature of the water.

The idea is that at idle the water is cooler so the fans can quietly spin at a low speed.

Under load I want the fans to automatically speed up to provide the extra cooling.

I want to be able to control the delta, the desired temperatures etc, rather than have the automatic fan speed controller take all control away from the user (me).

Preferably this system will not be software controlled, i.e. independent from the operating system, unlike, say, speedfan which I currently use to control fan speeds, but only works with windows up and running.

So I've been looking at various hardware fan speed controllers, but does anyone know of a particularly good controller that will fulfil the above criteria at a reasonable(ish) price?
