i've been meaning to ask you about you suggested power-supply quietening
technique. you said you moved the power supply outside the case, in order to
allievate the heat buildup inside the p/s case.

yet on at least my machines, the powersupply has ventilation holes on the
inside of the computer case, which to my understanding are used to draw heat
from inside the case. it's all very well having dual cpu fans on my athlon
drawing heat away from the chip. but without the powersupply fan, this heat
remains in the box, rising the ambient temperature and thus counteracting the
effect of the cpu fan - and lowering the life of your chip.

on the next note, you said the chip will crash if it gets too hot. if the heat
rises quickly then sure the chip will probably malfunction. but the real risk
of overclocking is the indetectable changes. in a process called ... well i
forget what it's called :) the tiny tracks on the chip will melt due to being
operated above their stated temperature, and then they condense elsewhere.
this can occur over the period of weeks to months, and by the time you notice
something is wrong, the chip is unsalvageable. that is why o/c'd chips often
can't be clocked back down again.
