ATX power supply fan noisy.
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. -- David Farber David Farber's Service Center L.A., CA |

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. http://www.dorothybradbury.co.uk/ Then find your local retailers for the equivalent. -- Adrian C |

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. |

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. |

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. P&M -- Posters should say what U,S. state if any they live in. Why do so many keep their state as secret as their own name? IANAL. That is, I am not a lawyer. |

There is no way a website can pretend to keep up with the stock details of thousands of retail stores. 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 think that a website saying "out-of-stock" would necessarily mean that a retail store in BF, Iowa, was also out of stock. 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 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. You don't know much about Radio Shack. -- Posters should say what U,S. state if any they live in. Why do so many keep their state as secret as their own name? IANAL. That is, I am not a lawyer. |

The word "all" includes even Radio Shack. 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." 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)..." 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? Gee, they even say they might not. From their online site: "...Prices advertised on this site are for online orders only." 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. So now you're going to call names. All this misinformation and irrelevancy about RS just to call me a fool! Well, I didn't call you a fool. I wrote that "only a fool would think..." If that description fits you, fine. If the shoe fits, as they say. As far as my "misinformation" goes, are you claiming that the information given at the site is incorrect? You don't know much about Radio Shack. Apparently, much more than do you. I also know how to read fine print at a website, including Radio Shack's. |

And latterly, of course, computer '3-in-1' does make an electric motor oil. -- Anyone wanting to run for any political office in the US should have to have a DD214, and a honorable discharge. |

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 |

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. -- Best Regards: Baron. |

Hi!
Not always a good idea. 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 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. |

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? G² |

writes 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. Funnily enough, I've just replaced one of those today. 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? 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. -- (\__/) (='.'=) Bunny's thinking about giving Windows 7 (")_(") a go despite what he's said about it... |
