Windows 95/98/ME Power management on laptop

I have a laptop set up with both Windows XP and Windows 98SE. When I use XP
the fan briefly comes on at full power then settles to a low level. When I'm
using 98SE the fan seems to be on at maximum power constantly, even when I'm
not doing anything.

Is there something in my setup of 98 that is sending incorrect messages to
the fan control (the BIOS, presumably) or is this a well known issue with
Windows 98? What could I try to solve this problem?

Grateful for advice.

Windows XP integrates power management technologies such as AMD's
PowerNow! (Cool'n'Quiet) and Intel's SpeedStep. Windows 9x does not.

See these links for technical info:

To add the PowerNow! or SpeedStep feature to Win98SE, see these links:
http://www.amd.com/us-en/Processors/ProductInformation/0,,30_118_10220_10221^964^4396,00.html
http://www.intel.com/support/processors/sb/cs-003772.htm

If your processor does not support the above features, or you cannot
find appropriate Win9x drivers, then download SpeedFan or Motherboard
Monitor plus a CPU cooler program such as Waterfall, Rain, CPUidle,
Vcool or CPU Cool.

Here is one example:
