Every time I write a post relating to the MacBook’s internal fans, I’m tempted to file it under our Apple >> Fans category (it calls to me). I’m pretty sure that’s not what it’s for, though.
Anyway, is your Mac notebook running on the hot side? Worried about singeing the tops of your thighs? You could buy insulated pants or you could check out smcFanControl. This simple, free app lets you control the minimum speed at which your Mac’s fans spin. Apple’s default is 1500 rpm; with smcFanControl, you can increase that up to 6200 rpms. Yes, it may sound as though you’re working in some sort of wind turbine, but it ought to keep your computer a bit cooler. I tested it on my MacBook and the fans spun up as requested; unfortunately, i don’t have a temperature probe on hand. But sure, let’s say it felt cooler.
The program only changes fan speed for the current session; if the computer sleeps or is restarted, you’ll have to run smcFanControl. And while the program only exists for OS X, it seems that setting the speed in OS X and restarting into XP via Boot Camp will retain the settings.

Update: Much as I’m worried about the tops of my thighs getting musical, I was in fact going for “singeing” and not “singing.” Thanks, Mike.
A hot MacBook is the only reason I sent my Mac packing. A utility such as this may have convinced me to keep it. Oh well, I suppose I'll just have to pick another one up when Core 2 Duo comes out.
BTW, I think you meant "singeing" instead of "singing ."
Great find. I've had heat problems with my MacBook Pro (week 10). Now with my fans set at a minimum of 3900rpm, my idle temp dropped from 67c to around 40c, and I can actually set the thing on my lap. Even when I'm editing photos it doesn't go above 50c. The area just above my F10-F12 keys is only slightly warm (whereas usually it's hot to the touch).
