One of the aspects of the audio/computer 'biz' that irritates me is
the way almost no-one shows any concern form 'mechanical' noises from
fans, hard drives, etc.

Please do a little reasearch on topics such as "Home Theatre PC" or
HTPC. The two general directions are systems that use so little power
that they are easy to cool, and fanless cooling systems.


I did, about 4 years back, and the cost would have been too high. And it
seemed so wrong-headed - low noise should be designed in, not bolted
on.

That is my view. Alas, home PCs and laptops are generally sold on the basis
of being 'powerful' with ultra-fast CPUs, etc. Which means heat to dump.
When choosing a machine for audio I deliberately chose a low-spec CPU as it
would then run in the machine with no fan.

Slainte,

Better yet, choose a high spec PCU and run it at reduced clock rate.
That will take even less power as dissipation is all in the rising and
falling edges. Underclocking could become the new overclocking.
