Fans bearing is probably broken
2021-04-12 06:33
Seems like a bearing issue. As long as the fan's RPM is fine, it shouldn't be a big deal IF you're okay with it sounding like a diesel generator. Otherwise buy a new fan, if you don't want to hear it 24/7.

it's not annoying if i make it way quieter but I can still hear
2021-04-12 06:38
How loud is it? Do you have to put your ear close to it to hear it? Is it the graphics cards fans?

Open the computer up and see what it is? Could be as simple as a wire from the fan is hitting the fan blades. Could be a bearing as well. You have to open it up to replace the fan anyway so why not see which one it is?

clean your fan will reduce the computer noise. and check your task manager which program are the most cpu/ram eater.

Sounds like the bearing on the fan has wore down. Need to replace the fan.

i think it varies a lot from brand to brand, so you will have to search in your fan for model code or something like this. But fans doens't need to be the exactly same as the others (maybe it's needed if you're using a software to manage the fan, but i'm not sure), it just need to be the same size and preferentially the same max RPM, or even above.

Just go to the prebuilt's website and check the parts.

probably cheap fan and the moving part is hitting the outer wall, u can try to wiggle it a bit otherwise just disable the fan completely by pulling out the wire if you dont want to replace it. obviously if it's the only fan that's not recommended, but since u say its prebuilt it's probably one of those RGB mass fan pc's and i'd just pull the wire out if there's other fans still operational

The fan bearing is worn out. Horizontally mounted fans tend to wear out quicker than vertically mounted. If it's the top fan and you're going to replace it, I suggest getting a ball bearing instead of sleeve bearing fan.
