Here is a screenshot of the CrystalDiskInfo 4.3.0 SSD and HDD information software, where is immediately noticeable, that the Crucial SSD is now also equipped with a temperature sensor. If this SSD reaches higher temperatures above approx. 75°C, it is able to throttle the SSD speed automatically. But it was not necessary even after dozens of benchmarks, but more on that later with a M.2 thermal image and in the M.2 infrared video.

Who like to reduce the SSD temperature, for example can a) adjust the energy saving settings or b) perform an active SSD cooling by direct ventilation or c) attach commercially available silicone heat transfer pads to the top and bottom of the PCB or d) purchase a special heatsink for M.2 SSDs.
