After going through the exercise of making my Athlon machine
ultra-quiet I can impart a few tidbits.
1) get a really quiet disk. The Seagate Barracuda IV 80gigs are
quieter than any of the already quiet laptop disks I have in the
2) get quiet case fans. The Panaflo FBA08A12L1A are a touch noisier
than the disk, but not much and the noise is mostly air-noise and
not the annoying motor-squeal that many other fans have. The
airflow in my computer case is quiet respectable.
3) get a high-flow case. The bigger the entrance and exit holes the
slower the fans can turn and still get the same amount of air
exchange. I really like my Antec 1040. (The OEM name for that
case is Cheiftec Dragon.)
4) the cpu fan needs to be replaced with something quiet. I put a
normal 80mm case fan on a 80mm to 60mm adaptor and used that
instead of the AMD OEM fan on the Athlon. This allowed me to
substitute a slower turning fan for the high-speed whiner that AMD
gives you with the boxed Athlons. Warning: Newer Athons put out up
to 80 watts. Mine was being an older model (1.1Ghz) only puts out
40 watts. You may need to get a much larger heatsink before you
can put a slower/quieter fan on it.
5) a stethoscope (or 3ft section of garden hose!) will do wonders at
finding the exact source of noise. If you've never done it, it
sounds silly as all hell, but try it. You'll be able to tell
exactly which rotating item is responsible for each part of the
cacophony you hear coming from the case.
