My Dimension 4500 is not as silent as it used to be, so I figured "noisy
power supply fan." Then I read a post in this group about running the
computer with the case open and listening carefully to determine the
source(s) of noise. Good idea! As it turned out, my PSU fan is actually
pretty quiet. The really noisy buggers are my two brand new Western Digital
hard drives, which emit a loud, high pitched hum.
The CPU fan hums also, but only when I place my ear right over the green
shroud. When I place my ear next to the grill outside the case, the hum is
much softer. My non-engineer guess is that the fan's own hum reverberates
inside the case, making it more noticeable when I run the computer with the
case closed.
Has anyone tried to replace the CPU fan? It looks pretty simple: Unplug it
from the motherboard and unhook it from the case. Is it really that easy?

[As for the WDC's - 1200JB & 800JB - I'm going to have to conduct more
experiments before calling Western Digital. I'll run them outside the case,
with only the power connector. That will tell me whether it's the drives
themselves that make the noise.]
