AH, thanks for explanation. I haven't read any major heat issues with using all 3 NVMe slots. I will be populating all 3 slots for Proxmox CEPH storage. Sticking with Minisforum's recommended Samsung PM983a 1.88TB Enterprise 22110 drives. Hopefully I won't have any thermal issues. Would be nice to be able to bifurcate on PCIe slot, but seems that's not possible.
