Fan shroud to mount an Noctua NF-A4x10 to an LSI 9400-16i HBA. Design idea copied from @BlackHornet_355398's fan shroud here: https://www.printables.com/model/377809-lsi-9300-16i-noctua-nf-a9x14-fan-shroud

I have a LSI 9400-16i, but this should work for other variants of the card such as 9400-8i, 9400-8e, 9400-16e based on pictures of them having similar heatsinks. The heatsink measures 100mm long x 48mm wide x 11mm thick. Also it looks like there is about 2.5mm between the heatsink and PCB. 

I left cutouts on 2 sides for different cable routing options. Can also rotate it around and the cutouts will be on the underside. Also included an option for NF-A4x20 but I don't have one to test fitment. This should work for any 40mmx40mmx10mm fan with 32mm mounting hole spacing. 

I printed with support enforcers on the 2 overhangs that go under the heatsink using Smart Fill and Organic Supports. PETG recommended.

UPDATE: It looks like there is an Lenovo variant of the 9400-16i with a 13 row heatsink. I've uploaded another file "BETA_Lenovo 430-16i_noctua_nf-a4x10_fan_mount.stl" that you can try for those cards. From some dimensions shared that Lenovo 430-16i heatsink is ~52mm wide with 13 rows, instead of the vanilla heatsink of 48mm wide with 12 rows.
