I love how quiet some of them are but I see at least ten times more of them fail than ball bearings, especially in heat, the sleeve bearing fans just can't handle heat as well. I have a recapped PSU here with a sleeve bearing fan that's going to be running 24/7. It has a Globe Fan sleeve bearing with maybe 2,000 hours on it. I have an NMB here, should I replace it just because it's a sleeve bearing? It is pretty damn quiet though...

Re: Do you replace sleeve bearing fans on site?
There are a lot of cheap sleeve bearing fans with inadequate lubrication (or none at all) straight from the factory. Make sure it's well lubed up. (ooh, matron!) -
Re: Do you replace sleeve bearing fans on site?
I always thought Globe Fan was good, some of the high end psus use themComment

Re: Do you replace sleeve bearing fans on site?
I decided to just replace it with the NMB and since it's actually quieter than I thought, I just soldered it straight to the board and now the PSU runs much cooler (It isn't very efficient)Comment

Re: Do you replace sleeve bearing fans on site?
Whether I replace a sleeve bearing fan or not depends on whether or not it has a good plug to hold the lubricant I use. Some fans just have a small rubber disc which just sits over the bearing housing, and it doesn't provide a very good seal, and oil just leaks straight out. Other fans (like the 10mm thick ones Antec use) have no plug at all. Again, the oil just leaks straight out of those and they fail. If it has a decent plug which seals well, then I just make sure it has enough lubricant.I love putting bad caps and flat batteries in fire and watching them explode!!

Re: Do you replace sleeve bearing fans on site?
The 10mm fans Antec used were Dynatron Top Motor or XFan. It seems to only be the 10mm thick fans that lack the plugs. The rear fans in those are also Dynatron Top Motor, and they have good plugs.
ADDA fans usually do have good plugs, but they fail because ADDA don't give them any oil from the factory. I haven't had any fail if I re-lube them.I love putting bad caps and flat batteries in fire and watching them explode!!

Re: Do you replace sleeve bearing fans on site?
Every fan I opened up are dry as a bone on the shaft. I oil it anyway even if it doesn't have a cap. In fact I just oiled the fan that failed in my SP300, now it's no longer seized...Comment

Re: Do you replace sleeve bearing fans on site?
With good shaft scrubbing and proper lubrication, I can restore just about any sleeve bearing fan. Worst I had was a 92mm Mitachi Spacefan. Completely seized and impossible to turn even by hand. Had to hammer the shaft out of the sleeve! After proper cleaning and oiling of the sleeve, it now works great. Granted I haven't used it much at all in a computer, but it still spins freely. I did do 2 other fans that were very seized, though. One of them is a 80mm Supperred that I have now used for a few months in one of my computers and a year or so in another. The other is a 120 mm "Raidmax", also in use for a few month. No problems whatsoever with either.
So no, I don't change sleeve bearing fans... unless the application requires total reliability in a 24/7 environment.Comment

Re: Do you replace sleeve bearing fans on site?
I always took my sleeve-bearing fans apart and lubed them back up with transmission fluid. (I'm sure there were better choices for lubricant, but eh.) Anything from case fans to the tiny ones on old video card processors or chipsets. They always fired right back up, quiet and fast... except for one which must have had a bad component on its tiny PCB.Presonus Audiobox USB, Schiit Magni 3, Sony MDR-V700Comment

Re: Do you replace sleeve bearing fans on site?
Wow, that's really cool! I've never done that before, how do you take them apart without destroying them? And do you oil everything except the motor?Comment

Re: Do you replace sleeve bearing fans on site?
Just peel back the sticker, take out the rubber bung if there is one, and put a few drops of oil in the shaft. Then put the sticker back on and spin it a few times until it spins freely. This can also be done as a precautionary measure.Comment

What kind of oil is best to use?

Re: Do you replace sleeve bearing fans on site?
I have never successfully oiled a fan by just putting a drop of oil on the top of the bearing like everyone recommends. The longest that has ever lasted for me was two weeks before it seized up or became noisy again.Comment

Re: Do you replace sleeve bearing fans on site?
Sometimes, it's tough to get a fan apart. Often there is a tiny c-clip at the top of the shaft or simply a plastic washer that has a split on one side so it can technically be fiddled out of it's slot. I find myself using sewing needles and other weird stuff to remove these parts at times, but it works. I always clean the shaft and bearing, sometimes running some 2000-grit wet sanding paper through the bearing, very lightly, just to debur anything miniscule. Lube, assemble, GO!Presonus Audiobox USB, Schiit Magni 3, Sony MDR-V700Comment
Isn't Globe Fan just a mediocre company so it probably isn't made too well?

Hello guys. I have a problem with a PNY XLR8 GAMING RTX3090 graphics card. The problem is that it displays and works fine, but the fans don't spin at all. The problem occurred when someone else removed the fans in order to clean it and broke one of the fan connectors. He replaced it himself and after that, it wasn't working anymore. I guess he damaged something else in the process. What i have done so far: I found 2 capacitors next to the connector that were in a bad shape, he must have touched them with his tools - they weren't shorted, but i replaced them with similar ones from a similar card....04-12-2024, 06:54 AM -
Good Afternoon, Good People.
I know this will be an elementary little project for most if not all of you, but I thought I would write a post and get put on track, rather than bumbling my way through it with all kinds of trials and errors.
I REALLY would appreciate y'alls help.
This is the problem - My wife and I purchased a big ol Victorian/Colonial House in NYC two years ago. The kitchen is surrounded on 3 sides by exterior walls, there is also a 1/4 of the kitchen floor (ceramic tiles) that has a crawl space underneath, and the kitchen gets FREEZING cold... -
I posted another thread like this for a TV power supply. This is for information purposes for anyone who has a bad one and wants to repair instead of replace. There is no model number on these but internally they appear to be the same, fan being the only difference I can find. If a component is damaged and can't be identified, this may help. One I have has the brand name XinJieBao on the front above the display. The other isn't marked.
My impressions. I can't say for sure on the chips and such but the HV capacitor is a very low quality one if I think. I tried to google it and also... -
This is a project that I'd like to get to at some point soon. I bought it 4 years ago and it's been sitting in the original box and even has a sticker on it dated April 6, 2006 from CompUSA. Unfortunately, it did not come with all of the modular cables; but does have enough for functionality. One 2 SATA power cable, and one 3 molex + berg cable. 20+4 pin and 12V 4 pin are hard wired.
It's sad that almost every associated company with this unit and the box advertisements are out of business: CompUSA, Mad Dog Multimedia, ATi, BFG, and Maxtor... lol

When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.
Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.
