I have been running this BeQuiet SilentWings 120mm 800rpm fan for about 10,000 hours. Until now. The bearing is worn out (sloppy) resulting in the fan making scraping noises. I pulled it out and made some measurements, just because I had a bench PSU, a multimeter and some other gear on hand.
Technical data of that thing:

My measurements (at 12V):
45mA running
50mA start up
Fan noise: 55.6dBC (Environment base line: 46.6 dBC)
reported rpm: 8752 to 9422
measured rpm: ~670
Thoughts:
I could and I will send it in. 20€ is too much to waste on a broken fan. I am not growing money on trees here.
The paint on the grey rings on both sides is chipping of. I might add a photo of that.
HAHAHAHAHAHAHA!
Extremly funny as the bearing is what failed. Better should have stayed quiet...

E-Mail to BeQuiet is on the way. Now we wait!

Conclusion
Well. Customer service my ass!
"Sorry but this is your fault" is how I understand the e-mail they sent me.
Running a fan on 10V for a bit over 2 years is wrong? So, BeQuiet, what am I supposed to do with your products then?
I was planning on putting my next rig into a BeQuiet case, power it with a BeQuiet PSU and cool it with a BeQuiet cooler. Seems it will be Thermaltake, Seasonic and Noctua then! Shame...
So Im guessing you put in twelve volts right and got those numbers?
Apart from the PSU being current limited to 100mA, yes.
Out of curiosity, what orientation did you have the fan?
Have you contacted Be Quiet! yet? They are supposed to have really good customer service.
It was hanging in the top of the case pulling air out.
So Im not sure what the reported rpm is bc 9000ish RPM is really high. Im guessing that is supposed to be 875.2 adn 942.2 right?
Which means the software is just reading the voltages that are going in and spiting out a number that is on some premade curve.
Also the current is only 5mA off so I would say the fluid in the bearing has gone to shit or gotten dirty. I would say since lube is self sealing you have some gap that lets dust get in and gunks up the fluid.
Also 23ish years is a long time to boast a fan will work. Thats a long time damn. What were they thinking? I dont know of any lube that would work that long. Even graphite has its limits.
Nope, those high numbers are what is reported. I first encountered them in the ASRock extreme tuner software. Shortly after that, the grinding and knocking noises started.
The difference in the current is within margin of error.
I mean, I could try to grab the raw frequency using my Fluke and try to figure out what is fucky from there.
Bearings never live that long. No idea what is up with that.
Ah ASRock. Love their shit. Terrible software. I would take what that says with a grain of salt. But again maybe the circuit in the fan is fried bc the fan bearing leaked. accounts for the grinding if there is no fluid.
If the bearing did leak then oil would go down to the circuit board based on the orientation right? I think
At least the RPMs are spot on. Measured that becuase what else is one supposed to do with a bunch of tools?
Oriantation wise, the bearing fluid would be in the hub furthest away from the circuit board in the back.
If everything is okay, the oil would be the light blue stuff. In my case, it would have become a puddle as represented by the blue line in the top (because the fan was pulling air out of the case).
I thought the motor sat on top of the board. so it goes motor board fan. Maybe thats for some fans bc they measure the actual rpm of the fan turning but i might be wrong with these.
well youre under warranty for like three years so why not. then youll have another 20 years of cooling lol right.
I bet there is some sort of air gap that is small enough the fluid wont come out but lets dust in.

Had a Dead Silence fan bearing go out, in the top exhaust position, blades started falling off stator lol.
was only $12
That's a bit disappointing. I've dealt with Noctua support and they're pretty amazing. One fan stopped working just out of the blue under regular working conditions. They told me break the fan and send them a picture. A week later I had a brand new fan in the mail, shipped all the way from Austria.
That sucks. At least you got two years out of them tho. That's pretty good for most fans.
Considering I have NoiseBlocker fans in the system that are now going to 4 years and BeQuiet advertising 200k hours runtime and 3 year warranty. That is more than disappointing.
Well you can do one of two things.
If it's fucked you cant fuck it anymore so fuck with it. See if you can fix it.
Or
Over volt that bitch
Then I would have to ask them to ship it back. Because they wanted to take a look at it...
1) I do not want to pay for a broken thing
2) The bench PSU I have only goes to 36V (Voltcraft LSP-1403 if you were wondering)
