This is a fan shroud for the AMD/ASRock BC-250 mining card. The idea is to stay close to the bounds of the PCB, while still providing decent cooling.

A 140mm fan is used as intake in the rear and a 120mm fan is used as exhaust in the front. It is designed with partially opened/straightened heatsink fins underneath the fans in mind. Look at the pictures for reference.

The shrouds are secured with clips and screws. The rear shroud uses the original screws from the support bracket, while the front needs longer replacement screws for the front bracket (8-10 mm should do). Fan cables can be routed underneath the heatsink and around the shroud.

A quick test at standard fan speeds, fresh MX-4 thermal paste applied and 2 Arctic “P”-series fans installed has the card running at roughly 53°C at idle and 65°C in games (GPU at 2000 MHz @ 950 mv).

Use supports as necessary for your printer. I printed mine on an SV-06 facing down with supports placed manually.
