that will be difficult, I don't have an nvme capable thing for any

that is a great point, the mainboard comes with inbuilt heatsinks, but
when I assembled it, the 2nd nvme slot heatsink looked a lot less
bulky than the other one, I remember distinctly wondering if it would
cope. If it happens again I'll see if I can get a temp measurement
at the time of failure.

I would hope temperature throttling would not be quite so brutal, to
remove itself from the bus entirely, but its a reasonable explanation.
