I would like to replace this two-wire, 80mm square, power supply fan. The
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.

Is there a Fry's near you? It has a variety of fans, in various sizes. You
can probably find a close or exact match.

Yes, there are Fry's in my neighborhood. I will check it out.

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).

Is that, " £0.50p" some type of currency? (-;

How much is that in US dollars and cents?

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.

If you caught it in time, you can try relubing the bearins which will
get you by for a while.

Remove from PC and soak in 30 weight oil, clean up, put back in

I got another 6 months out of mine

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.

Hi!

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.

William

Hi William,

Thanks for the tip on extending the lifetime of the fan.

Over here every man and his dog wants at least two in their PC tower
case. Some with pretty coloured lights that flash and change colour at
random. ;-)

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 don't know what you call expensive. A good quality fan is not very low in cost.

Search out the catalogs or on line for a fan that will mechanically fit, and will work using the same power requirements. Take care for the air velocity, because a high rated air velocity could be too noisy if this is a concern.

Haven't had any experience of them yet.

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.

My PSU fan seized solid, very solid (nice and quiet, though). The
replacement seemed rather noisy for my tastes. I eventually got the
original fan freed off. [It needed the application of a hot soldering
iron to the end of the spindle.] It ran for 18 months after being well
re-oiled with WD40. It was still going fine when, some time ago, I doing
a spot of once-in-a-while spring cleaning inside the case. So I re-oiled
it again with some '3-in-1' oil. It's still running fine.
