Heat dispersal

To protect from overheating, the CPU has an internal temperature sensor
that triggers a cooling fan or lowers the CPU operating speed.

Use Power Saver Utility or the TSETUP program to select one of three
temperature controls.

Maximum performance
(Windows 95)
Auto 1 (Windows 98)

Turns on fan first, then if necessary lowers
CPU processing speed.

Performance (Windows 95)
Auto 1 (Windows 98)

Uses a combination of fan and lowering
the CPU processing speed.

Battery optimized (Windows
95) Auto 1 (Windows 98)

Lowers the CPU processing speed first,
then if necessary turns on the fan.

If the temperature rises to a certain level, the cooling fan is turned on or
the CPU operating speed is lowered. When the CPU temperature falls to a
normal range, the fan is turned off or the CPU speed returns to normal.

If the CPU becomes too hot with either setting, the system enters Resume
mode and automatically shuts down.
