Abnormal ventilation rotation speed ML360 sub - zero

hello,

I currently have an ML360 sub zero cooling system with an MSI Z590 Gaming plus motherboard with the latest BIOS and an I9 10850K CPU.

I have the cooling system pump which makes an abnormal and unpleasant noise, the bios shows me a rotation speed of about 4700rpm.
What would the problem come from?

This system is directly connected sata I however respected the wiring diagram as on the instructions.

thank you who can help me.

either the system does its job well but this pump makes a lot of noise
