R740 GPU Air Shroud 0RFFDP

This is the so called GPU air shroud for the R740 and R740xd servers. It is designed specifically for certain GPUs like the Tesla M10. The shroud is installed first and then the GPU. It is reported to maximize airflow especially for larger graphics cards. It should be noted that this shroud is incompatible with the 2U high performance heatsinks. 1U heatsinks are required to use the shroud which in my opinion might not be a worthy tradeoff depending on your CPU, and also considering that large graphics cards work just fine with the 2U heatsinks and normal air shroud, albeit with perhaps a minor hit to air flow efficiency.
