Best fan controller

[carlazai]

So i am moving to a crossfire system where my case is going to need more cooling. As i use my PC for work as well I dont want the fans going full pelt 24/7 so I am looking at a fan controller for my system.

What is the best fan controller available? Are the temp sensors worth installing?

I would prefer software but can easily live with manual.

The fans will be the standard 3 pin versions.

I was looking at a aerocool version to slot in front of case

The software sounds ideal though a little annoying to lose a USB header. Anyway going to order one based off the recommendations
