ATX power supply fan noisy.
David Farber
power supply is used in an AudioReQuest music server and is powered on
continuously. The part number is, NMB-MAT 7 followed by a model number of,
3110GL-B4W-B54. 12V DC, 0.30A. I've found a few places online that have them
listed but when I call they, don't have them in stock or the price is
prohibitively expensive. Is there some generic fan that will replace this
and not cost more than the power supply itself?
Thanks for your reply.

Get the data sheet for that fan (it's probably old, hence out of
production), and compare with the information available on this page for
newer fans.

Then find your local retailers for the equivalent.

Any 2-wire, 80mm, 12VDC, 0.30A (approx) will do. Got a Radio Shack nearby?
http://www.radioshack.com/product/index.jsp?productId=2102826 will do.
Probably cheaper at some place like Frys.

Find another fan that has the same mounting holes (80mm -- note the
*thickness* of the fan, also!) and operates at 12V with <= 0.30A.
Chances are, it's just a generic fan.
If you have access to a lot of surplus fans, look for one
with a ball bearing *and* something that is "quiet" (assuming
noise is an issue).

Sure, if you're to use cable ties and/or duct tape to mount it and assuming
the replacement isn't thicker than the original.
Otherwise, it's good idea to check the thickness and mounting method.

Well, that particular model is no longer made, but the 3110 series were
1" (0.98") fans with a standard mounting hole pattern. The same hardware
that was used to mount his old fan would work on the RS model.

That NMB fan is actually a pretty good quality unit, although I have
seen some failed ones over the years.
What you might do to extend its lifetime is to simply oil the
bearings. That will quiet it down and keep it running for many more
years to come. Just lift the label, remove a little rubber plug (only
with some fans) and drop some light oil in there.
Even if you replace the fan, you might want to do the same thing to
the replacement. Doing so can drastically increase the lifetime of the
fan, especially if the replacement is cheap.

Since this is for a client, it needs to last longer than 6 months. Also, the
cost of transporting it back and forth costs more than the fan replacement.

Not always a good idea. Some have a synthetic lubrication which will
turn into sludge if you add a non synthetic oil to it. You can
sometimes get away with it on sleeve bearings particularly older fans.

I doubt the tolerances are that close in this sort of application. From what
I've seen, and from pre-emptively oiling fans before they could fail, very
few fan makers provide much of any additional lubrication to the fan
bearings. It's a rare fan that I've exposed the bearings on and found a
chunk of grease in there.
Of the fans I've rejuvenated by oiling, only a few were unresponsive to
treatment or would not continue running. These were the cheapest of the
cheap--all the rest continue to run perfectly.
William
AZ Nomad
>William
I've never had the any luck rejuvenating fans with lubrication after the
fan's bearings have started to howl. By that stage of the game, the fan's cheap
worn out plastic bearings have so much slop, that nothing short of perhaps axle
grease will fill the slop.

While ball-bearing fans have the longevity edge over cheap sleeve bearing
fans, they aren't necessarily quieter. And newer sleeve bearing designs,
such as Nidec's NBRX sleeve bearing, have made great strides in longevity.

WD40 isn't a lubricant. It was developed for 'Water Displacement',
or in plain english, to spray on ignition wires that got wet.
Which '3-in-1' oil. That is a brand, not a type.

It penetrates well, and prevents/halts rust. It also serves as a
sort-term lubricant. Despite what the purists might say, it does work
well as a switch cleaner/lubricant.

Which dries into a nasty, insulating film over time. I use PTFE to
lube small motors. It Works a lot better than WD40 ever could, and lasts
a lot longer.

Radio shack has a great webpage in many ways, but one enormous flaw is
that if you click on a link, it might say the part is out of stock,
even when stores have it.
I signed up to get an eamil when their remote A-B switch was back in
stock, and after months I got it, and figured well maybe it's also at
a store now too. So I went in and they had two and the clerk said
they had never been out of them.
He was very confident, and I had gone in the same day I got the email.
It seems unlikely they had in stock items actually shipped for the
same reason they sent me the email. They probably did have them all
along.
So to with the item above. It says it's out of stock, but when I
click on Find it in STores, it gives 10 stores around here that it
seems to say has it. I'd call some stores and see.

I like the "3-in-1" spray on lithium grease because I can reach hard to

As with all websites (Petco, Best Buy, Home Depot, etc.) information
given for a product (availability, price, etc.) is for the website
ONLY! There is no way a website can pretend to keep up with the stock
details of thousands of retail stores. And only in a minority of cases
does a retail store match the price of a website. Only a fool would
think that a website saying "out-of-stock" would necessarily mean that
a retail store in BF, Iowa, was also out of stock.
I just bought a nice vinyl screen door (I'm 200' from the ocean) from
Home Depot that wasn't even available on their website. Apples and
oranges.

The first paragraph is a digression. OTOH, you've digressed by
bringing up other websites as if one could deduce what RS is like by
knowing a little about what they are like. It's true that
many websites act almost like the stores don't exist. For example,
the discussion of warrantee on one was not accurate wrt to purchases
made at a store. And Home Depot and Lowes have terrible pages in
general. Once I looked at kitchen faucets at a nearby Lowes, where
they had 8 models that I could have used. When I wanted to review
them later that day, the website showed none at that location, and it
was hard to find out about any other location. Lowes used to ask what
zipcode the user lived in and then pick a store near there and call it
his home store. If they didn't have what he wanted in that store, the
computer user had to come up with another zipcode and see if the store
there had it. They've improved slightly. Now it looks iirc at my
"home store" and then the two stores nearest my home store. But I
have a car. Just tell me the closest store that has it and if I'll go
there now if it's important enough, or maybe I'll be nearby soon. --
I apologize. I have digressed.
I gather you have posted without knowing much about the radio shack
website. One of the reasons I called it a great webpage is that it
does indeed "pretend to keep up with the stock ....of its retail
stores." And not only that, afaict, it actually does keep up with
them. I made a mistake when I needed the A-B switch of not checking
the stores, so I'll never know what it said then, but in other
situations, when I wanted something that day (unlike this switch which
I knew I wouldn't use for weeks) I have looked for individual store
information and what I found appeared to be correct when I got to the
store.
Of course I won't know what happens between the time I check the
computer and the time I get to the store (although I could call and
ask them to reserve it for me) and of course there is shoplifing etc.
so actual stock doesn't always match inventory records, but with
computers it's not hard at all to keep track of inventory for each
store. They probably did it anyhow and then just made it available to
customers.
> And only in a minority of cases
>does a retail store match the price of a website.
Their own website? It's you who recommended a radio shack part. Do
you think that RS doesn't charge the same price at the store as
online?** And what does this have to do with the OP, who likely
wouldn't quibble about a dollar or two when he hasn't been able to
find what he wants anywhere else so far? **Plus they have free
shipping to any participating store, which I'm sure is almost all of
them. Since they have stores in almost every US state, they charge
sales tax on internet orders too, I presume. If the store has it,
it's just as good as online and it's quicker.
>Only a fool would

So now you're going to call names. All this misinformation and
irrelevancy about RS just to call me a fool!
Anyhow, he'd think that if he figured the stores never stocked it at
all, and would only have it if he had it shipped to the store.
Because like you say, stores don't stock all the same things the
warehouse does.

I've never let one go so far as to howl. Nor have I heard one do that!
The fans I've oiled were usually making a grumbling noise and it was
intermittent in most cases.
There's no harm in trying it.
Just about three days ago, I broke a blade off of an Intel CPU
cooler's fan. I puzzled about what to do, as the fan is an unusual
type and I don't have any other Pentium III compatible coolers sitting
around. What I finally did was to super glue the blade back on. The
repair appears to be robust after two days worth of running. What's
more, the balance appears not to have been affected at all by this
little "whoopsy".

Not at all true. I suggest you read the "ITEM AVAILABILITY" section
of its website:
"...Some items are either temporarily out-of-stock online (and may be
available at your local RadioShack retail store)..."

Gee, they even say they might not. From their online site:

Good fix. I was in a similar trouble but didn't have the blade so I
placed two small rubber belts held on the nearest blades to balance
the fan, worked quite well.
I've had limited success oiling fans, usually it won't last long as
the oil appears to evaporate or go somewhere else. I tried several
oils for motors and none of them last. Some evaporate and some harden
and end up locking the fan. I belive the manufacturer used some sort
of special grease, I have seen similar grease used in sleeve bearing
motors for video heads in Philips VCRs that after years of operation
preserves its properties intact.

Pity the chip it will be cooling is not going to be kept in service
for 34 years.
Maybe it has a chance to last that long in an IBM mainframe!

Why would you even waste time on a PC power supply fan? Are you going
to check the capacitors that are very likely going bad too? You can
buy an Antec EarthWatts 380 Watt supply from Fry's for $30. High
efficiency, power factor corrected, auto switch 120/240, variable
speed cooling fan. Isn't your time worth anything?

Funnily enough, I've just replaced one of those today.

Yeah, you can use a generic replacement but if it's powered 24/7 it
won't last long. Find a good quality ball-bearing replacement from the
likes of NMB-Mat, Panasonic or Papst. You'll be glad you did.

Try a silicone-based lubricant (with a consistency between that of oil
and grease). Expensive but it works.
