Question Pc case fan rattling noise

[Shirox]

Hi,

My pc case is an aerocool aero 1000. One of the front fan is really loud (the bottom one). I never installed new fans nor tried to fix them. So my questions are:
1. How can I fix it if it is fixable at all?
2. How can I access to the front fans? I can't/don't know how to remove the front dust filter without damaging it.
3. I tried to check where are they plugged in but couldn't find it. The mobo has 2 place for case fans but one of them is empty and the other has the back one plugged in. I don't even see where are the front fans cables are or how are they connected.
My mobo is asus h170 plus d3

Hello
Lets start with this, how old is the fan? And to gain access to the front panel and to remove the dust filter look in the manual for the case. Can also be found here.

Check for anything maybe hitting the fan or any other observations and let me know. Thanks!

And to answer your questions.

1. More than likely, we just have to narrow down the issue.
2. Consult the manual found here.
3. is there maybe a fan hub or are they connected to a splitter from your PSU?

Thanks for your answer.
The fans are at least 7 years old.
When I last checked (from inside the pc) there was nothing that touched the fan.
I don't really know how a fan hub looks like and didn't even knew that you can connect them to the psu. Even when I took off the other side of the pc where the cables are I couldn't point out which one was the fans's.
I can check the pc and fans again tomorrow. Maybe I should take some pictures too?

Sure some pictures would help. But maybe its time for some new fans, We'll have to see though

I don't have time today so I will try to post the pictures tomorrow.

So I took apart my pc and the bottom front fan (that's the loud one even if I spin it with my hand a little is loud) had some parts that came off. I took some pictures.

Maybe these will help, I guess tha fans are conected with the osu under the hdd/ssd drives?

 

[Shirox]

It's still loud and the bottom one spins slower than the rest. And as I said even when I started spinning the fan with my hand it gave out the same sound.

If I have to change it can someone tell me how and what size should I buy?

Good photos - well done!

First, it IS possible that the fan has a worn-out bearing and needs to be replaced. The typical symptoms of that are:
From a cold start the fan makes a lot of noise, but after 5 min or less it gets silent.
If rebooted while still warmed up, fan is silent
Period of noise gets longer as many days (months?) go on.
Eventual y the noise is permanent

However, that may NOT be your case. The photo of parts that fell off shows a fan hub sticky label that fell off, and two small items. At least one of those looks like a stick-on rubber circle used as a noise suppressor that should be between a fan frame point and the sheet metal it is fastened to. Further, one photo appears to show that the bottom fan is farther away from its mounting plate than the one above, as if its fastening is loose. So MAYBE that fan really is simply rattling around just because its mounting screws (inserted from the front) are loose and the rubber pads are missing. Try this. With the case open so you can reach the fans easily and the noise happening, just touch that fan's frame gently and feel whether it is vibrating. Now push it firmly against the mounting plate so it cannot shake, and see if that stops the noise. If it does, try tightening the front mounting screws.

If that does not stop the noise, carefully touch the spinning fan blades to stop the fan completely, then let it go again. If the stopped fan is silent, then you know it IS that fan making noise.

If the fan bearings are worn, you cannot repair. You must replace. See if you can trace the cables from each fan to a common point where they all are connected. A photo of that would help. Also then trace where a cable from that common point goes to - a mobo header, or maybe a PSU output. You'll need this to work on replacement. Let us know what you find.

The first thing that you described is what happaned with time, and now the sound is always there. The thing is if I have to replace it, that a little stressful for me because I don't really like doing works inside my pc and even now I tried to trace back where the fans cables are going but I'm just not sure. I tightened the screws but didn't help.
