Stupid little fans
Zypher
were experiencing North Bridge fan failures.... LOL - well I have two Epox
(8k7a+) computers and sure enough! Fan were noisy and failure was on the
horizon.
I rummaged through my box of computer junk and found an old Pentium computer
heat sink with one of the same little fans attached... (same size, same
screw pattern, and in fact, same stupid Mfg.! It worked great! But I only
had one. For the other computer I rummaged some more, and found that those
plastic "removable hard drive bays" have little fans in 'em, and sure
enough, it was the same stupid little fan from the same stupid little Mfg.!
Can you believe it. And upon inspection of my NVIDIA TNT2 board, guess
what's on there? Yup that same stupid little fan. But don't try and buy
one of these little $5 fans at any computer place. They only sell CPU fans
which are way too big physically. Anyway, for those who are experiencing
the same fan failure, you can find them on several other things.! Check out
your junk box!
Just a tip!

You may be able to revive the fan with a drop of oil (I used Singer oil
which is a general purpose fine lubricant oil; silcone oil is also good.)
Remove the fan, and carefully lift the edge of the sticker covering the
centre bearing with a knife blade. Peel the sticker back enough to
reveal the bearing in the middle, and apply one drop of oil to it.
Allow the oil to seep in to the bearing; spinning the fan by hand or
blowing on it may help. Clean off any oil when the sticker stuck, and
then stick it back down. (If it doesn't stick, a thin film of white glue
on the edge of the sticker will do the trick - don't use strong glue!)
Refit the fan, and fire it up. With luck, it should be back to normal.

Yeah, I did exactly that with my noisy Northbridge fan a couple of
weeks ago and it`s working perfectly now.

protection! If your fan started making noise
you should replace it unless it is one of multiple case fans .
This trick,from experiance will not last more than a few months in most
cases (no pun intended) and by adding oil
to it you risk not hearing it when it does fail!
Somthing to consider ....good luck !

I'm somehow in the motor business (big motors) and these little jewels are
of the 'sleeve' variety. There's a small copper bushing generally, and have
a felt around them to hold the oil. I'm not sure that's what's here, since
I haven't taken one apart, but generally speaking, if you use 3 in one for
example, its penetrating quality will get to the rotating surface and
lubricate for awhile, but alias the heat will cause the oil to dissipate.
The best thing to lubricate a sleeve bearing with (in a warm application) is
going to be turbine oil. It's generally thin and stays thin even under the
warmest of applications. But it's difficult to get it to penetrate the
sleeve if the sleeve's been dry. But here's the killer - if you ever so
slightly get too much oil on the bearing surface, and it 'slings' to the
motor windings, it will cause the insulation to fail on the winding. (And
we all know what happens when you let the smoke out of a motor!) So take
heart and be careful. For me, I just went for replacements. One of which
was an actual ball bearing, (little nosier - but will last longer.)

I take your point, but these fans are not regarded as critical, not on
the 8KHA+ anyway, and many people run without a fan at all (unless
they are overclocking). So i`m not worried if it eventually fails,
I`ll get a new one then.
But you`re right, and it is something for the OP to consider.
Cheers

board back. I've been doing fan lubrication for years and have only
one improvements whats mentioned here and it will work for years, not
months..
After you apply the oil to the shaft, apply a small dab of white
paste lubricant to the shaft such as lubriplate. Oil will migrate
and free up the fan ok, but after a few months it will need oiling
again. The white paste lubricant will easily double the time before
the fan siezes up again.
