A simple custom fan shroud for XFX Merc Series graphics cards of the RX7000 series.
Low profile, accepts any 120mm fan using M3 hardware. Uses M3 threaded inserts (d=~4,2mm, L<7mm).
Includes optional flexible exhaust duct (soft TPU).
Mounts to stock heatsink with original screws and either 2 M2x6 or some glue to secure two halfs together.
fans pictured are noctua A12x15 connected to GPU fan socket by soldering noctua Y-splitter cable directly to one of the stock fans leads. GPU easily supports the power draw of most 120mm fan configurations.
Total card thickness is (45mm + fan_thickness) so ~60mm with 15mm slim fans or 70mm with 25mm thick fans.
Print in high temperature resistant filament as card is semi passiv and heatsink can reach 70°C for prolonged periods even while idle.
For the flexible fan duct I used Extrudr Flex Semi-Soft “A88” (feels much softer) and it works like a charm.
Glue exhaust duct to exhaust port or print using a multi material system.
Stock fans are very loud while the 2x noctua 120x15mm configuration is not audible in my circumstances even under 200W loads with a 3°C delta_T improvement vs the stock fans, while still using the stock fan curve.
For SFF users I also have a model up for a flexible fan intake duct in a similar style to ensure that only fresh air is drawn into the heatsink.
Parts:
-8xM3 screws for attaching fans
-6x M3 threaded inserts
-4x of the 6 M2 screws in the stock fan shroud
(optional if using exhaust duct):
-4x M3 threaded inserts
-4x M3x10
-glue (recommended: Bu Lai En B-7000)
-fan Y splitter cable to create custom wiring harness
