Well you have an Asus Mobo that will have some kind of Q-fan function available.
This means that if you plug the fans into the headers on the Mobo Q-fan will adjust the speed of the fans.
They will only speed up when necessary.
(In the winter when my tower was near the back door it would see temperatures near 0 degrees Celsius. I would turn the computer on and the CPU fan would start to spin about 15 seconds after XP is up and running! The chip set fan would start soon after... when things get a little warm.)

With the 4 pin molex your going to have to use a manual controller unless there's an auto controller interface out there.
