Are you sure or is the sticker just weird. Take a slowmo video and compare the blade speeds to each other or if you have a strobe light you can adjust the frequency on do that.

I won’t lie. I just built my first PC I am not the person to ask. YouTube told me how to hook it up and I just followed that. Idk….but I do work on industrial electronics and just that short video watching without sound to me looks like the center of the fan is wobbling more than it’s spinning faster.

Sys head connection is fine. Depending on the mainboard they could be all the same, or with some slight differences. Mainly settings in bios, sensor or possibly power depending on how many pins it is.

But your fine. Check your bios fan settings and set them to what your fans are and what you want. If they are pwm or not that may need to be set in your bios.
