Fan noise - possible causes?

Despite opening and cleaning both the main fan and CPU fan on my Mesh
Athlon 1800, it's still occasionally making some bizarre sounds. Hard
to describe, but basically, instead of the fain 'swish', it changes to
a sort of deeper growl, repeated several times, then maybe returning
to normal for a while.

Before I dusted and vacuumed the fan areas, it was worse, and I was
able to temporarily stop the groaning/growling by slapping the case.
Presumably that dislodged dust. But, with that now effectively
removed, I'm puzzled why it's still intermitently noisy like this?

When fans go bad, noise is often intermittent. Pulling back the sticky
plastic bearing seal, and applying one drop of very lightweight oil should
bring temporary relief. But in the end, it's replacement - hopefully with
a ball-bearing fan.

Unplug the power cable of the chassis cooling fans
If the noise stopped, the cooling fans bearing may be worn out, buy a new one
If you can still hear the noise, Check the fans of the CPU, vedio card and the power pack
Use a can of compressed air to blow the dust out of the fans

Fans fitted by sys.manu. are v.often pretty basic and can become noisy. The
same applies to sys case which can be a source of vibration.
You can pay £90+ for a decent case
If the noise dissappears by slapping the case it sounds more like vibration
/ resonence, once again a std.cpu fan/cooler combo can be pretty basic. - I
changed one on an old sys fitted with an oem cooler and cured the
noise/vibration - theyre not that expensive.

A fan that is not securely fastened (loose screws) can cause noise. So can
worn out fan bearings. Also a loose case cover or loose internal sheet metal
that can vibrate will make a noise. If it is the fan, simply replace it.
They are very inexpensive.

Follow the advice that has been given but, DON'T SLAP THE COMPUTER!!! You
can very easily destroy your hard drive.

Well, that's the point, isn't it? If a computer misbehaves, it should be
punished. Sometimes I even toss mine through a window. It's a great feeling.

It's a case fan. The cpu and video just suffer from a silent death then a
system freeze, these fans don't have enough mass or power to overcome
sticktion.

I second that.

And vacuuming isn't a good idea either, unless it's a vacuum specifically
made for electronics, or you'll learn some interesting lessons about static
and computer components.

Good point on the vacuum. Some things I take for granted, after the
"slapping", I shouldn't have.
