I'm seeing these on almost every NVMe drive I service but have not yet one I've been able to get my hands on for a spell, to investigate. Since there's such a wide range of vendors, and many drives are brand new, I am running on the assumption that it's less alarming than it might seem. I did look into the NVMe spec with one device's specific error codes but...they were all vendor reserved!

Temperature thresholds will be device-specific and you should be able to find them if you dig into the spec sheets. Since there are no moving parts they can be more tolerant of higher temperatures. No spindles or heads to worry about!
