[ubuntu] How can I gain control of my laptop fans?

http://ubuntuforums.org – Hi guys, I'm running on an old Fujitsu T4020D,and installed a full Ubuntu 9.04 (updated it to 9.10 already, in attempt to fix the fan-heat issue) and the fans just aren't spinning until it gets really hot, and then only for a second or two at seemingly even intervals. I can't check the fans in windows xp, because I have no way to install it. No DVD/CD drive, and no floppy disks to install it via win98 off of itself. xSensors tells me that the "temp" and "remote_temp" are both 0C Help please? Also, if anyone can tell me this info, it would be awesome. What's a general minimum speed for fans in laptops, and what's a general maximum? (Hardware)
