I think you should always worry about any temperature measured on a
system that's in the >= 65C range. as Jim mentioned, the temps
that matter are actually on-chip and not really accessible - and it's
unknown to us what they should be anyway, or how long they can
tolerate particular temps. and whether over-temp failure
modes would be transient (conductivity in semiconductors changes
rapidly as a function of temperature) or gradual (electromigration
or perhaps the solder-ball problems nvidia had)...
the original question was about wheter 60-65C is a safe operating
temperature. I think it's pretty clearly high - whether it's critical
depends on how it's measured, the specific chip's specs, etc.
but it's not the sort of operating range I'd be aiming for.
But there should be possible to save money by running hotter. Suppose
you could accept 10 degrees higher temp, then you would not have to run
the AC in the room as hard (and AC represents a significant part of the
operating cost). If the price you pay is that your CPUS will only last
for 4 years (I'm just speculating here, and for the moment only consider
the cpu) instead of 10 years it would probably be an economically much
better option.
