Ubuntu 9.0.4 Presario S4000NX Fan Speed

Question

I recently install Ubuntu 9.0.4 on a Presario S4000NX and the CPU fan speed is kept at max. With Windows XP installed the fan speed would increase/decrease as required.

I've tried to install lm-sensors and run the sensors-detect. It recommended that I load the modules which I did:

smsc47m192  
i2c-i801

When running sensor-detect it gave me this strange message:

Trying family SMSC
Found SMSC LPC47M15x/192/997 Super IO Fan Sensors
    (but not activated)

Running the sensors command gives me a list of voltages and CPU and temperature but doesn't list any fans.

After doing some Internet research I then tried to load the smsc47m1 module but I get the following error:

FATAL: Error inserting smsc47m1 (/lib/modules/2.6.28-15-generic/kernel/drivers/hwmon/smsc47m1.ko): no such device

The file smsc47m1.ko does exist in the listed folder.

Any suggestions for getting the fan speed (and the noise) down in Ubuntu? Thanx.

P.S. - I would have put better tags but Server Fault wouldn't let me.

"Install 10.04," says the voice from the future.

Answer 2

Have you ever updated the BIOS? I don't know if it helps (or if there's a newer BIOS available for your system) in your case, but for example with my Dell Latitude D830 laptop the original BIOS version caused deadlocks during docking/undocking, WLAN didn't work very reliably and so on. With the later revisions everything's been fine.

Also, upgrading to Ubuntu 10.04 would be a good idea.
