hard to find CPU fans

The fan on my CPU is whining. My processor is an Intel Pentium II 633.
When opening up my PC, I noticed the fan is a Sanyo-Denki 10x6512H1106
Does anyone know where I can find replacement CPU fans for older processors?

FWIW I've bought fans from www.jameco.com with good results. Dalco,
Altex (just down the road from me) and Digikey also come to mind --
their web sites have the obvious domain names. You may have a local
shop, too.

I don't think it's critical to find the exact same model, as long as you
get the same voltage, mechanical size, and 2 or 3 wire configuration,
and get one that moves at least as much air as the original. You may
have to splice your old wires to your new fan, though, so a soldering
iron may be required.

In fact, even if you get the identical model, chances are it'll just
have plain wire connections, so splicing will be necessary.

Take the Fan off.In the centre of the motor spindle there is usually a
small plastic cover sometimes underneath a sticker.You can get this
off and drop a few drops of light oil in there.I've even used clean
cooking oil.Then clean off with a bit of clear alcohol and dry and
replace.
HTH :)

The times I've tried that, it merely delayed the inevitable, and not
even for very long. But YMMV.

processors?

I'd just grab a new heatsink/fan combo. They're widely available. For
example:

I don't know of a source for that, being one of Intel's lovely
proprietary snap-on units. Those Sanyo-Denki fans were often pretty
whiney even when new to a few months old, they just didn't have an
adequately sized bearing, IMHO.

If you think you can get the whole heatsink off, which is probably
held on by what Intel called "riviscrews" (or something like that),
and need a precison hex driver (or was it a star driver? It's been a
while.), then you can just get a whole new heatsink. Those screws are
NOT easy to get off, I vaguely remember stripping a few and ended up
drill them out.

That being a ball-bearing fan, oiling it won't help a whole lot to
combat "whining", might actually make it MUCH louder, is typically
what happens when oil thin enough to get into a ball-bearing, does.

The easiest solution is probalby using a good knife to cut off the
hole center, round fan assembly off of the plastic, leaving a circular
hole. Then drill four holes around it for screws, using the new fan
as a template for the holes. I "think" a 50mm x 15mm fan will fit,
barely, though you ought to measure as it might only have room for a
40mm fan.

If a 50mm fan will fit I suggest something like this:
http://store.yahoo.com/directron/5cmfan.html
Directron has a $10 minimum order though, IIRC, and that particular
fan I have bought before and know that it needs a looped red wire cut
where it goes to the third pin and the contacts swapped in the plug
(hard to understand from my description but should be clearer when you
see it). The plug is standard, fits on a motherboard header but that
fan doesn't have an RPM signal.

Cooking oil will gum-up after a while, eh? I'd use 3-in-1.

3-in-1 will not last long. IMO best stuff is some light grease from your
local model shop.

Since we're announcing our favorites, mine is Tri-Flow with Teflon,
available near the bicycle chains at WalMart.

Mines fishing reel drag assembly lube, also with teflon. Although I might
look into this Tri-Flow thing, it's gotta be cheaper.

I like 5W30 synthetic motor oil - dirt cheap, and I suspect the
detergent additives help disolve any old dried-up lube. I've been using
it for about 3 years and haven't had to repeat the procedure on any fans
yet.

I prefer silicon vacuum pump oil. I get it, from work, for FREE.

I might have to look into buying a small bottle of it. I can't afford to run
it in my car since I've been on an invalid's benefit. :-(

I always used to use Mobil 1.

Smallest bottle I found was 500mL - enough for several lifetimes of fan
refurbishing. You could probably get an 'empty' bottle at the local
garage and still have enough for a dozen fans or more :-)

Amidst all the creative ideas, my favorite was always something called
"Phil Wood Waterproof Grease" sold in finer bicycle stores. I wasn't
sure if this implied that Phil Wood also made non-waterproof grease,
but the grease he did make seemed to last for a few years when smeared
on all the plastic washers and packed into the brass sleave-bearing
before reassembling.

Synthetic gear oil here, with a tiny bit of moly grease mixed in when
it needs be thicker for badly worn, proprietary fans that can't be
replaced too easily, or with non-vertical mounts where it's less
likely to run out. I don't know if I'd call it a favorite though,
there are a lot of uber-expensive machine lubes now that might be
better but costing about 200X as much, just not worthwhile for a cheap
sleeve-bearing fan.

AS P2B suggested you might be able to get a few dozen uses out of an
"empty" bottle. Even so 5W30 is a bit too thin... the ideal lube is
one barely thin enough to get in-between the shaft and bearing, being
as thick as possible to both fill the gap now present from bearing
wear, AND to prevent it from running out over time or being forced out
due to imbalance. Also consider that as the shaft turns and with fan
integrated into the system, it gets warmer, thinner film and runs
more. A great lubricant that doesn't get into the bearing well or
stay in the bearing isn't as effective... I suppose to a certain
extent that means the ideal lube may vary per fan. It wouldn't be
very effective trying to lube something like a Panaflo with thick
lube, but then I don't recall the last time a Panaflo needed lubed,
those things run for decade(s) in the lower RPM models.

The downside to thicker lube is that it may reduce RPM a few hundred
RPM... not necessarily a bad thing, depends on the situation. On the
other hand if the bearing is pretty worn and the shaft is slapping
around in it still due to overly thin oil, it may run as slow or
slower than if a thicker lube was used.

Oh, boy. First the arguments over which thermal stuff is best,
now it's about the fan lube. Hmm, perhaps there is a market here
to tap? "Arctic Lube". ("Hot Lube" is another enterprise
altogether). ;-)
