After testing the toric rubber rings, I've concluded that they do not provide a comprehensive solution to the fan vibration issue. These toric rubber rings don't eliminate the direct contact of the screws with the chassis. This is a design consideration that could potentially be improved upon. One possible approach could be to seek out specific fans without vibrations or redesign the fan mount to minimize any contact or proximity with the chassis and components. This could enhance the overall performance of the camera, especially in terms of vibration control.
