FYI, I'm currently running a Celeron 300A at 450MHz (100x4.5) and it is
stable and cool. It's in a Asus P2B board with a heatsink/fan and doesn't
need a aditional fan case. I don't have a hot running 3D card yet though.
The 300A is the same processor core, Deschutes, as the newer PII's but
instead of the 512KB cache running at 1/2 cpu core speed like the PII's, the
Celeron 300A and 333 have 128KB running at FULL cpu speed like the Xeon's.
I ran the bus at 103 for a while, but I got occasional crashes. It's been
stable at 100 though.

I agree, software isn't the answer for something like that. I could see how
it might be handy to extend notebook battery life, but not for overclocking
a desktop that you want to run rc5 on.
PS I'm getting 1.3MKps from this machine on RC5-64 and the CPU cost $105.
