I have been unsucessfull in underclocking modern CPUs - all use fixed
multipliers (cynics say all chips manufactured to same spec, locked to
force price differential)
P133 etc are out unless you have RAM or they use modern SIMMS not 72pin.
Some MBs will let you under-clock the FSB down from 66MHz/100MHz which will
allow fixed-multiplier processors to be under-clocked
Worst-case heat production is waiting-to-boot (bios screen)
eg power fail
server crashes
ws boot to bios screen and wait
There was a rom-o-matic option to power-save.
Running X with MIII-300 at 100M: CPU temp was 40C
Waiting CPU temp was 60C and rising
I found a micro-ATX case, and a quiet CPU fan: in a quiet room straining to
hear above the hallway clock ticking: ummm ... YEP its on.
