5毫米风扇降噪垫 - 5mm fan denoise spacer
Print Profile(1)
Description
When fans are pressed against the case or radiator, turbulence is generated, causing unnecessary noise. Raising the fan can effectively reduce noise.
While raising the fan, I referenced the design of a silent fan, shaping the air inlet to gradually converge, which might help further reduce noise (or it might not).
For the exhaust side, it is recommended to place it in reverse, which helps converge the airflow.
Three designs are provided: common rounded corners, common 45° chamfers, and less common non-45° chamfers (which my GPU radiator's built-in fan actually has). Use as needed.
