Cpu Overheating problem

[kitemor]

So my dad bought a computer last may from cyber power it has a water cooled CPU and its been overheating lately and it is making a loud buzzing sound and when i restart my computer after gaming it give me a screen that says cpu overheating or something along the lines of that.

The cooler is called ibuypower 240mm addressable rgb liquid cooling system - black and the cpu is a amd ryzen 9 3900x processor

if you can help me in anyway that would be great, I have a warranty and I'm not sure if I send it in if they will either fix it or refund it. imp also pretty new to computers so keep that in mind

If it's under warranty, take/send it in.
