I currently have the non-NVMe / 12G iteration of the Supermicro Rear Hot Swap 2 x 2.5" NVMe kit and would like to swap in the NVMe variant, but have some concerns over what NVMe drive temps would look like. Two questions for the community:
1. Both servers have 3 x FAN-0126L4 (7000 RPM) / 72.5 CFM / 1.09 in H20 static pressure) in them behind the HDD backplane (and also both have 2 x 2U SMCI active CPU coolers, if I'm being thorough). Fan mode (X9 board) is controlled via script based on max 3.5" HDD temp (of 12), but even at a high ambient (78F), Optimal keeps HDD temps under 40C. I prefer to stay at Optimal as Standard becomes audible and Full is untenable (the poor servers are mounted in a condo "server closet" and upside down at that - they must think I hate them). I don't want NVMe drives added in this manner to be considered in fan mode control and want to ensure they will be sufficiently cooled @ Optimal (which I suspect may be a pipe dream).
2. Looking at the design of the kit, I fail to see how the cutout in the backplane can provide sufficient airflow for NVMe drives (backplane is nearly identical for NVMe and non-NVMe kits) ...
This cutout provides enough air flow for two 18W - 25W NVMe drives ???
Further the engineering looks whack - it hits one at the top / one at the bottom of drive ...
The air shroud would aid air flow a bit ... but enough?

- I'm curious if anyone has NVMe drive temp figures for the Supermicro MCP-220-82619-0N, and if so what does your cooling scenario look like (x fans @ y RPM, etc)?
- What is the best way to connect the MCP-220-82619-0N (2 x Oculink) to an X9 board? [There are a number of ways (SFF-8643 PCIe adapter w/ or w/o switch+ Oculink to SFF-8643 cable | Oculink PCI adapter + Oculink cable, etc. - haven't reviewed various options for cost effectiveness yet)]
