Of course there is also the risk that I might fry the CPU by cooling
the CPU passively using the Coolermaster Standard Sized heatsink
instead of using the supplied CPU Fan or trying to detach the
heatsink to use the foxconn one attached to the P2 266.

I could get an adapter if push comes to shove for a couple of pounds
if things get too hot. But according to tomshardware P3 Coppermine
(and predessors) has a cut off point when a CPU gets too hot and the
system just hangs without damaging the CPU so if that happens I`ll
have to buy an CPU fan adapter.

The AMD CPU (of a few year ago at least) don't have this protection
so they fry if too hot - tomshardware tested by running the Intel vs
AMD CPU with no heatsink/fan whilst running Quake3.

So its virtually impossible for me to fry a £ 6.40 CPU

The CPU arrived this morning. I opened the case removed the P2 266 and slot
in the P3 600E Slot 1 1.65v CPU without CPU Fan connected. PC boots BIOS
informs that thermal sensor is no connected and CPU is not supported F1 to
Boot. I pressed F10 under System Information shows P3 600E as CPU.

Boot into Windows ran SiSandra;

It says Core Voltage 1.65v I don't know if that means the Compaq is giving
1.65v or thats the info being recieved from the CPU. But no problems so far
the machine is running 2003 Server eval at the moment and its much faster
then before. It feels so much more responsive just like it should. A bargin
for those with old Compaqs / people who can't get a 600mhz + for free from
bank/school.
