I can't help on the choosing CPUs part, but I can share my experience
with a P4 for a VDR. The thermostatic control fans reduce noise, but
are not really silent. I replaced both the power unit to a totally
fanless one, and my CPU cooler is Scythe Ninja Rev B, which is totally
silent (had a Zahlman AlCu7000 if I remember correctly, before).
Then I have an additional 120mm fan running slowly inside the box, but
that I cannot hear outside.
The most noise right now comes from my Seagate Barracuda hard drives,
which are pretty quiet, but still noticeable. Especially one of them
which has probably bad bearings.
I also tried throttling / underclocking the CPU to reduce heat, but my
MB starts an annoying whining noise if I do that, so I could not use
But my advice, if you really want to reduce noise in a VDR, is to go
for fanless choices.
If you don't do other processing, any current desktop processor would
have enough processing power. For Full HD it could be different,
