Ventilateur bruit aigu

Hello, I bought a Katana 17 B13VFK-1223CA 17.3" - Core i7-13620H - RTX 4060 - 512GB SSD - 16GB RAM - Windows 11 a year ago. Every time I open my computer, I always turn on the fans, as the salesperson told me, it's better to break the fans than a more important part due to overheating.

This week, I noticed that my fan makes a high-pitched noise when I open or close it. When it's running, it works perfectly without any problems or strange noises, but it's only at the beginning and when I close it that the noise is high-pitched, and I find this abnormal. I opened my computer completely and gave it a good blast of air to remove the dust, but the high-pitched noise is still there.

i try to send u a quick video of the sound when i turn off my fan but i cannot put a video here

Thank you
