Ok its been a week my computer has been making a weird noise. It's not graphic card fan, we checked that. Its not power supply unit fan, we tried 3 different ones. I took my PC to the computer repair service and they told me to get a new CPU fan so i did and the sound disappeared for 2 days and now it's back.
I'm pretty sure it's something mechanical. All the temperatures are perfectly fine and the sound doesnt change when i play games or do something usage heavy.
It can also disappear by itself or by inclining the PC case...
I have only 3 fans and it's none of them that causes the problem. Its a heavy, loud drilling noise as if the whole PC was shaking. It can have different intensities.
Im thinking about calling for a PC technician but i wanted to ask for advice on forums first.
Do you have any ideas what could be causing that? The noise is super loud but i don't think it's dangerous at all to my PC
EDIT: Also, before buying a new CPU fan we dettached the CPU fan (with my friend in my house) and the noise persisted even without anything being attached. How is it even possible?
