How to clean a laptop cooler if it cracks during operation?

Question

Cooling systems

Hello. The laptop is half a year old. Asus X570UD. The cooler began to crackle during operation - a uniform noise, as if something was catching and interfering with it. What could it be? How to treat? How and what to lubricate?
The computer itself is cooled by the norms, I did not notice a strong overheating. So far there is only extraneous noise from the fan.

Answer 1

Most likely thirteen for the fan. Replace with a new one for this model.
