This is a remix of the bollio's original model on thingiverse. I have added some cutouts to improve airflow. The original auther stated that this baffle was for the Mellanox ConnectX-3 CX312A. But I have a CX322A, and it works just fine.
The fit is a little janky, but it works well enough. I only used the screw hole on the side with a M3 threaded heat insert.
If you make a better version, definitely drop me a comment.
