[NTLUG:Discuss] fan frequency and duration

[Fred James]

All
Mandrake Linux 9.1 or 10.0 on a laptop (Gateway 450SX4)

Is there a way to adjust the frequency and duration of the running of 
the chassis fan?  I have not found anything on the fan in BIOS.

I am concerned that the fan does not seem to run as much under Linus as 
it did under the Windows in stall.

Thank you in advance for any help you may be able to offer
Regards
Fred James
