I apologize for continuing this thread, but I pulled off the case side and
determined the CPU fan is making the noise. The fan is a standard "AMD" CPU
fan. Could someone recommend a quality fan that should last more than a
year? TIA for your time and trouble.

I was ready to write that I could probably just give you a new unused
stock AMD heatsink and fan but upon checking my junk closet it appears
that I might have chucked it in the trash -- at least I can't locate it
at the moment. If the fan in question is one of those odd frameless
types that is buried in a stock heatsink I don't have any idea where to
buy a replacement. I invariably skip the stock units (AMD or Intel, I
don't discriminate) and install a nice copper many-finned cooler with a
larger quieter fan in the systems I make even though I don't overclock.

Good luck with it.

You could try one of these. CNPS9500A from Zalman (A = AM2). Uses a clip
and the existing frame on the motherboard. $49

http://www.zalman.co.kr/ENG/product/Product_Read.asp?idx=277

There are ~1200 reviews here.

http://www.newegg.com/Product/ProductReview.aspx?Item=N82E16835118223

On that one, the manual shows a three pin fan connector. That
can be connected to a four pin header, but one pin will be left
unconnected. If a motherboard uses PWM fan speed control, then
the fan will run at full speed. By placing the provided Fanmate controller
in series with the cable, and twisting the dial, a lower fixed fan
speed can be selected.

I use another Zalman cooler, and run it at a fixed speed all the
time. My CNPS7000 has been running for more than two years of fairly
heavy use. I put the computer in suspend to RAM at night, so the
fan doesn't run 24 hours a day.

The easy answer is, don't guess or play random odds.

If we could just play odds, the failure wouldn't have
happened in the first place, right?

Check all fans, and those that have sleeve bearings are
probably due to be relubed right about now, especially those
that are thinner and/or running at higher RPM, and/or not in
a horizontal orientation if they're sleeve bearing fans.

If we wanted to play odds, it'd be the video card or a
motherboard chipset fan. Odds are, that's the problem, but
that won't be a consolation for those who have a different
problem.

No - that is something else. That is temperature sensitive fan control - as
found in media centre PCs like those from Shuttle (only example I am
familiar with). This kind of fan noise is just a loud fan that is throttled
down (due to its noise) to lower speeds when things are only 'warm'. This
fan noise will sound like an engine revving up or down. I think the original
problem is more a fan starting to fail - a loud vibrating noise? Does that
sound right Goff?

Yes. It sounds like a vibrating noise. I accidentally hit the box with my knee
when it was noisy and it went back to quiet. The fan is dirty, but because of
the blades, I can't get to the fuzz blocking some of the fins.
Anyway, I don't see how the fan comes off. Does anyone have experience
with the stock AMD fan setup and its removal ?? Thanks for all the help.

If it is the CPU cooler fan that is on its way out, then you need to get it
sorted out as an overheating AMD processor will burn itself out (not like
intel, which throttles itself to prevent overheating). You can either buy a
completely new heatsink/fan (sometimes called HSF) and replace the lot
(perhaps go for something quiet) or you could just replace the fan. You will
find it is harder to get hold of replacement CPU fans, most shops just sell
standard size case fans (40mm, 80mm, 90mm). What you might consider is
removing the broken fan and installing a fan bracket with a large fan
attached - you will find these in a number of places - I can think of
www.quietpc.co.uk. This is a metal bracket that screws on where your PCI
cards are attached to the case and you can position the fan above the CPU
cooler.

I would avoid getting a second hand HSFs (from ebay or elsewhere) as you
don't know how long a second hand one might last!

I would personally see this as an opportunity to upgrade - find out what the
maximum processor your motherboard can take and buy one of those in a retail
pack (not OEM) and you will get the heatsink and fan in the box - new CPU +
new fans to boot! I am guessing, but your AMD 3700+ is probably socket 939,
so can probably be replaced with a dual core Athlon 64, maybe 4600+ or
faster. Why not stick a little more memory in there at the same time?!!

Replacing the CPU would not affect any software unless you move from single
to dual core, in which case, Windows XP may need to be re-installed or at
least repaired.

You cheapest and easiest option is to replace the fan - if the old one is
failing, then don't worry about breaking it when you remove it, but search
google for help on "replacing stock AMD 939 HSF" and there is bound to be
something.

Second easiest (almost as easy as fan only) is to go for a complete new HSF.

Hardest, but best outcome is to replace the CPU and HSF.

Keep us posted!

It's a 939/3700. No screws. I called AMD tech support this morning and got full
instructions on removing the unit. Unfortunately, or fortunately, the heat sink
and fan come off as a unit.
Since the unit is only about a year old, they are sending me A NEW
FAN/HEATSINK AT NO COST. At least one consumer is ahead of the game if
only temporarily. Thanks to all for your responses. You're very accomodating.

It is absolutely safe. and much smarter, to stick your finger on the
hub of the fan, to locate a problematic fan.

The rubber hose may still have its uses though. In a computer. I think
it was initially or previously used in diagnosing problems with cars..

I remove parts too to find noises. Basic troubleshooting! Easier to
stop a fan though. If it is a fan.

Is there a reason why you set your posts to dissapear from archives?
Is it because you think your post is not worth keeping?
If it was any use, don't you think it would be a crime .

I have seen the symptoms similar to what you speak of. As you say,
"normal".

It was from SpeedFan in the BIOS. The fan starts at full speed, and
when speedfan is off, it continues. But when speedfan is on, it goes
quiet, and only rises when and whilst the cpu gets over a certain
temp, until it goes down again.
It was loud immediately after turning it on, and went quiet during
POST.

But what the OP mentioned, was fan going loud after POST (presumably
after POST had -finished-, and continuing afterwards)..

If it was only loud momentarily and then went quiet, I doubt it would
bother him. He seems quite keen on dealing with it.
