The airflow is too loud.

"1. The operating principle of bladeless fans is to ""compress and accelerate air at high speeds before expelling it."" Compared to fans with blades, they operate at slightly higher speeds, and moderately reducing the airflow velocity produces a softer sound.
2. Disconnect the power and inspect for loose screws or components. If no abnormalities are found, please provide a video of the issue and the device log."
