That the fan starts running means at least that, probably the BIOS, is 
keeping the system from getting too hot.

Do you have the packages "acpi" and "acpid" installed? If not I suggest 
you try that first.

You could check in the /proc filesystem. Something like:
$ cat /proc/acpi/thermal_zone/THRM/temperature

For most systems you can get additional info on fan and temperature by 
loading the correct i2c modules and installing/configuring the sensord 
package. It's not quite plug and play though, you'll need to read the 
documentation.

For that to work, the command 'lspci' should show a line similar to this:
0000:00:1f.3 SMBus: Intel Corp. 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) SMBus 
Controller (rev 03)

On some systems this device is hidden, and you probably won't be able to 
use the sensord package without a lot of effort.

Maybe there is nothing wrong. Laptops try to conserve power by not running 
things if they're not needed. So the fan only switches on if the 
temperature gets too high and will slow down or switch off again if it 
cools down. It should not let the system get too hot though.

Cheers,
