You can do a smartctl command in terminal to get the temperature of the nvme drive. Might have to install the package beforehand depending on the distro. For example:mmm, I don’t have a temperature reader that I can point at it. Does an nvme drive expose temperature through sensors or s-tui command? NVME drive I used is from Lexar.
The bottom of the case (where the nvme drive is) is cooler than the top though and cpu temps are around 65-70 degrees while stress testing so within limits…
