Question : Problem: How to control fan speed in Fedora?

I've just gotten a new server (Chenbro RM21508ML chassis w/ Intel S3210SHLC motherboard) and put Fedora 9 on it.  Things are going well so far, except that the case fans run full-tilt 24/7.  It's going for co-location so I'm not too worried about the noise, but I'm concerned that it will shorten the lifespan of the fans.  Unfortunately, I have no idea how to persuade them to calm down.  Does anyone have any thoughts?
