I think that you'll find that it's not the CPU which has a fan on its
heatsink...

You should be able to find and fit a quieter fan if you really need to.

I've not seen cpufreq working ‒ it seems that this is only supported on some
Atoms: http://en.wikipedia.org/wiki/List_of_Intel_Atom_microprocessors.

I see no reason why not. (I used a spare CD/DVD drive, though.)

In fact, that's what one of their telephone support people in Chile told a
tech to do for a board with DOA audio. The reason for this is that they
need a single platform to validate returns. There are too many flavors of
linux, bsd, etc. to define standard diagnostic tests for each.

They may not "support" linux, but they have validated the board on various
flavours of linux. See
http://www.intel.com/support/motherboards/desktop/d945gclf2/sb/CS-
029860.htm

The fan is on the GPU (not CPU) . Earlier board versions were reported to
have loud fans which failed with alarming frequency. Later builds appear to
have resolved that issue. Replacing the fan yourself voids the warranty.
The CPU runs an average of 50 degrees C in an air conditioned area with
exhaust. Fan noise also can be amplified or attentuated by the enclosure
you choose.

Yup, you are right. I discovered this too late to 'save face'

Yup. Am looking at PSU's that have large diameter / bottom mounted / low RPM
fans and get it to perculate over the M/B

They (apparently) do. Further delving into the Intel site has revealed such
a claim.

Do you really need MiniITX, or would FlexATX work just as well. IME, you
pay more for the smaller form factor, but often get less. I looked at
getting the Intel Atom 330 board (D945CGLF2), but went with a Supermicro
X7SLA-H-O instead.

Another option is an old laptop. That could give you a lot of extra
features that you might need (onboard screen, power supply/battery, self
contained, and semi-rugged, etc.)

Just wondering.
