L.D.:

Regarding any issues about cooling and noise for later (or even early
model "SurvPC") PC's go over to http://www.silentpcreview.com/index.php

Also tell your resident boy/man techno geek to fire up his mechanical
engineering thinking cap and take a look at their homebrewed solutions
http://www.silentpcreview.com/article103-page1.html . With a hand saw
+ pile of wood and a pair of tin snips along with a trip or three to
your local 2nd hand electronics hardware depot you all can solve most
of the heat and noise issues for just a few bucks.

High quality large diameter RELIABLE fans (vs Fry's Electronics or
similar retail locations el junkos) are in the less than $15 range -
some of the smaller diameter ones are in the $9 range.

I have built case filters using the "gray" foam plastic packaging
materials - then wash it out every month or so. Keeps mucho cat hair
off the little things on the mobo. Cat hair being an excellent heat
conductor which causes excellent grounding too.

However, fine the cat hair results are they are not quite as permanent
an el destructo solution as a large volume of male cat spray when your
running the box without covers and forget to shut your SOHO door - I
have TWO (2) mobo on the shelf which prove El Gato is much craftier
than John's remembering system's lack of functionality A.K.A.
oldsheimer dis-e-ase.

I have also built wooden enclosures which held four tower units and
had HEPA filters from Grangers and MULTIPLE low speed 110V fans for in
& out and internal air circulation - remember I helped at local AM/FM
radio stations which are notorious for Rube Goldberg el cehapo
solutions ...

Your okay on the memory stick choice. No personal experience with
aftermarket heatspreaders? However they should be 85% to 99% as good
as when the higher speed DDR RAM memory stick comes with them installed.

With only 64MB of video RAM I doubt you all need anything like a video
card fan. Again check out my favorite web site about heat & noise.

Look at comments on choice of CPU as a room heating system at
http://www.silentpcreview.com/article31-page1.html

Your Intel P4 Willamette core (1.3-2.0 GHz) is rated as "Early P4s
with typical power from 49W to 75W, these hot processors are difficult
to cool quietly, despite the large HS form factor. Serious
undervolting and underclocking may work. Thermal protection throttles
speed under high loads so maximum power (100W for 2GHz) may never be
reached. Thus, these (and all P4s) very tolerant of thermal abuse.
20/7/02"

Next see what the homebrewed gurus thought up at
http://www.silentpcreview.com/article103-page1.html
This should make ALL of us rethink what background noise and heat we
have in our "SOHO" offices, even with a P-I class 166MHz or a P-II
class 233MHz.

My old faithful AMD K-6 233MHz decided after seven years to act up. I
quickly added an off-the-shelf small cheapy 110V fan and slid open the
case by an inch {our male el gato is no longer living, another story
for someday about loosing my 18 year office buddy). I didn't pay much
attention to the increased noise. Then I read this web site and bought
a quality $10 ball bearing low-speed 12V fan = my ears were wondered
why my brain was so slow to catch onto background noises.

Without the expensive test gear for noise and heat you are at the
mercy of the gurus who chase this stuff around their web sites.
However, if you read a bit and then ask yourself the question "can we
do this for less than a weeks worth of groceries" and the answer is
yes - start figuring out a way to send out boy/man techno geek to
collect stuff. If your getting used stuff, make 'em let ya spin up the
fan. If the dang thing sounds like a Huey Cobra on steroids, just pass
even if it is free.

next up?
