reid,
athcool saves both temperature and power. Its a very simple script,
written for athlons.

Description: tool to enable powersaving mode for Athlon/Duron processors
athcool is a small utility for enabling/disabling Powersaving mode
for AMD Athlon/Duron processors.
.
By enabling Powersaving mode you can lower power consumption and
CPU temperature when the CPU is idle.
.
Powersaving works only if your kernel supports ACPI (APM does not
work), because athcool does only (un)set the "Disconnect enable when
STPGNT detected" bits in the Chipset's Northbridge. To really save
power, the STPGNT signal has to be sent when the CPU is idling. This
is done by the ACPI subsystem when C2 state entered.
.
!!!WARNING!!!
Depending on your motherboard and/or hardware components, enabling
Athlon powersaving mode sometimes causes:
.
* noisy or distorted sound playback,
* a slowdown in harddisk performance,
* system locks or instability,
* massive corruption of the filesystem (observed at least once).
.
If you met those problems, you should not use athcool. Please use
athcool AT YOUR OWN RISK.
.
If athcool works fine for you, and you want it to run automatically
on startup, please read the /usr/share/doc/athcool/README.Debian
file.
