I'm hearing people say that the Barracuda 7200's aren't the legends of
quietness that previous models were. Instead, the Samsung Spinpoint
line is said to the new quiet king.
The forums at silentpcreview.com are a good place to get hardware
recommondations like this. The site also has an interesting table of
the relative power usage of CPUs.

The NorthBridge fan on my new Abit KV7 is hardly audible.

Or buy a motherboard that allows voltage control and undervolt it. This
reduces heat at the cost of performance, but these days who really needs
100% of the potential speed of a processor?
I belive three motherboard manufactures have features for managing
noise: Asus, Aopen, and Abit. I have just brought an Abit because I
read that it's feature for lowering CPU fan speed according to CPU
temperature works better than Asus's. You can lower CPU voltage on most
of these companys' boards.
Another feature you will definitely want to check out is motherboard
support for ACPI performance power states as implemented by recent
Athlons (Bartons and I think Thoroughbreds) and Durons (1.4 MHz and up).
(I belive this is also known as S2k Bus Disconnect) This allows the CPU
to vary it's power usage (and therefore heat generation) according to
load. There's not much written about the on the Net but you can read
about it in the technical documentation on the AMD site and 2/3 down
this lengthly article:
