I have the same problem with a Compaq Presario c700. cat /proc/acpi/thermal_zone/TZ01/temperature returns 0C, and the fans don't turn on. Restarting acpid had no effect; same with unloading/reloading the 'thermal' module. The only thing that seems to work is a hibernate/resume cycle once it's warmed up, or a full reboot, though I believe the reboot can be at any temperature (I haven't tested that specifically yet).
