LSI 9300-16i Dual Ducted 40mm Fan Shroud

Ducted Fan Shroud for LSI 9300-16i HBA card to fit 2x 40mm fans.

I wanted a better solution for cooling my card than just having a single 40mm on the heatsink with nylon screws into the fin gaps.
I sketched up a shroud that clips over the heatsink and is fed by two 40mm fans that are mounted far enough back so as to avoid completely blocking the next PCIe slot.
The fan mounting holes can be drilled out if you need larger than 2mm.

I have a Silverstone RM43-320 rackmount case with the front fans swapped to Noctua NF-F12 Industrial PPC 2000rpm fans set at 85% and the 2x40mm Noctua fans on the HBA are also set to 85%. The HBA sits at 50-55C
