Regardless of the fan(s) you use, have you looked at the
Crystalfontz CF633 units? It can do two things your system
needs, 1) monitor temperature probes and 2) control fans.

Which is to say, it can be used to throttle those screaming loud
fans right down to nothing when they aren't needed.

It takes a bit of non-trivial software development, but a water
cooled system controlled by a CF633 can monitor temperatures in
a number of locations (coolant and air), and automatically
adjust the fan speed to the heat load. It also has failsafe
shutdown hardware for ATX power supplies.

The blurb on it is here,

And the data sheet is here,

I'm using 1 serial model and 1 USB model, and have been extremely
satisfied.
