This is a Tesla duct model for M4, P4, T4 cards. Should also fit to A2 & L4, but so far those cards have not been tested with model (use at your own risk).
Custom designed shroud is a perfect way of cooling a passive-heatsink NVIDIA Teslas (not included) listed above in a desktop/workstiation/server case. This shroud (together with the fan, not included) is engineered to fit precisely to the card, and to meet/exceed the card's cooling requirements. Model is optimised for good hand feel, without sharp edges & quality of design according to best engineering practices by a engineer with a degree, but also protected with logo (not shown on photo, only in STL). 3D printing material advised: ABS, ASA, HIPS, PP, PC or Nylon.
Model is tested & suited for 40x40x25 server fan with M3x30 screws, thin nut ISO 4035 M3 with small washer DIN 433 (tightening parts not included)! Using other tightening sizes at your own risk to fit with part.
Item dimensions: 61x61x40mm.
