80mm to 50mm fan

thingiverse

Mounting an 80mm Fan to a 50mm Hole Requires Creativity and Ingenuity. One Potential Solution is to Use a Custom-Made Adapter or Spacer, Which Can Be Fabricated from Aluminum or Plastic. This Adapter Would Allow the Larger Fan to Fit Securely Through the Smaller Opening While Also Providing a Clean Path for Airflow. Alternatively, You Could Utilize a Flexible Ducting System, Such as Silicone or Rubber, to Connect the Fan to the 50mm Hole. This Method Would Require Some Creativity in Routing the Ducting Around Obstacles and Ensuring a Smooth Flow of Air Through the System. In Both Cases, It's Essential to Ensure Proper Sealing Around the Fan and Adapter/Spacer to Prevent Any Leaks or Gaps That Could Compromise the Performance of the System.
