This is a cooling shroud for the NVIDIA Tesla V100 FHHL GPGPU.
This custom designed shroud is a perfect way of cooling a passive-heatsink NVIDIA Tesla V100 FHHL GPGPU (not included) in a desktop case. This shroud (together with the fan, not included) is engineered to fit precisely to the card, provide ample clearance for power cables, and to meet/exceed the card's cooling requirements. It can be 3D printed using PLA. When installed, the shroud + fan assembly adds about 11cm to the length of the card.
