Yes - that's certainly a valid way of looking at it, Ben!
But bearing in mind that semiconductor reliability decreases exponentially
with temperature - and also the fact that my own system stabilises nicely in
the "cool" mode most of the time the way I use it - I think that I prefer to
use the C&Q rather than not.
The variation in temperature of the power supply components is reduced if it
incorporates a temperature controlled fan.
Another point is that most of the failures I have experienced with PCs are
related to fan failure, particularly smaller ones like chipset or CPU fans.
They go noisy then seize up. I therefore like the idea of running the CPU
fan only occasionally, which is what happens in my own system.
On the other hand, I used to set my system to spin down it's hard drives
whenever they had not been used for a while. I have stopped doing this, as I
get the feeling that regular contact start/stop cycles are probably more
detrimental than leaving the fluid bearings spinning...
