I am running Ubuntu 11.10 on my Dell Studio 1558 laptop.

Everything works, but the fan stays on the whole time. Better than not working at all, but still irritating.

I installed lm-sensors and when I run sensors I get the following output:

Adapter: Virtual device
temp1: +26.8C (crit = +100.0C)
temp2: +0.0C (crit = +100.0C)

Adapter: ISA adapter
Core 0: +44.0C (high = +95.0C, crit = +105.0C)
Core 2: +44.0C (high = +95.0C, crit = +105.0C)

Adapter: PCI adapter
temp1: +75.5C

fancontrol gives me:
Loading configuration from /etc/fancontrol ...
Error: Can't read configuration file

and pwmconfig gives me:
There are no pwm-capable sensor modules installed

Any help would be appreciated
