I assembled this PC 8 months ago. Until now it worked perfectly:
Motherboard: Asus ROG Maximus XII Extreme
CPU: Intel Core i9-10850k
GPU: Asus TUF RTX3070
RAM: 32 GB
3 SSD and 1 HDD
This PSU should be loaded at half with these parts.

Is anybody having any idea why these noises appeared?

If it is indeed "a fan hitting a wire" (or hitting something) which I think its very possible....it may be that something is expanding due to heat over the coarse 1-2 hours and causing the interference.
It may also be a bearing loosening up.
I would RMA it or replace it.
That noise would drive me nuts.
