These are 3D printed cooling shrouds for the AMD Instinct MI25, MI50, and MI60 Accelerator cards.
These Shrouds are printed in ASA for increased heat and wear resistance.
The 75mm version is significantly quieter but does not move nearly as much air. It adds about an inch to the lendth and width. The fan is rated for 13CFM and is the GDSTIME 75mm x 30mm 7530 DC 12 Volt Brushless Turbo Blower Cooling Fan 2Pin this can also be found on Amazon.
If you have a fan you'd like an a shroud for let me know, I'm always looking for better cooling solutions.
I've only tested these on the Instinct MI series.
Check the pictures for dimensions of the connecting plate.
