What are you all doing with the PCIE slot?

Only way worked is limiting PCIe to gen3, using gen 3 NVMe. The problem is the SSD very close and facing PSU and gets very hot. if only there is adapter with M.2 slot on the opposite side. However. This won’t run OS as it will crash frequently. Only used for storage.

If the OS doesn’t run reliably, I wouldn’t trust it for storage.
