    Hello
    I checked the disc for the first time and I am a bit concerned about the temperature. The program is red and I do not know if this is normal temperature for M.2 SSD or not. I have an SSD for sata and he has 33 degrees and the one on the pcie up to 71.

    Opis parametru Composite Temperature z dokumentacji Kingstona:

    Quote:
    Composite Temperature: Contains a value corresponding to a temperature in degrees Kelvin that represents the current composite temperature of the controller and namespace(s) associated with that controller. The manner in which this value is computed is implementation specific and may not represent the actual temperature of any physical point in the NVM subsystem. The value of this field may be used to trigger an asynchronous event.
    Warning and critical overheating composite temperature threshold values are reported by the WCTEMP and CCTEMP fields in the Identify Controller data structure.


    Nie musi to być temperatura pojedynczego punktu. CDI oszacowuje tę temperaturę przeliczając sobie wartość RAW ze stopni Kelvina na Culsjusza, ale ten parametr raczej nie ma szans odnosić się do faktycznego pomiaru (co zresztą w cytowanej dokumentacji napisano i na co wskazuje słowo "composite").

    From what I see, the temperature is not bad, but it could be a little lower

    65 degrees is indeed not a low temperature. Unfortunately, some NVMe disks are quite hot. For me, such a "decency limit" would be 50 degrees, although of course there is no scientifically based value dictated by anything.

    What is the disk mounted in? Laptop board, desktop board, PCIe-M.2 grommet?

    Look for better ventilation in the enclosure if it reaches such temperatures. A fan injecting air on the front of the housing or possibly on the side above the ssd can slightly improve the case.

    Added after 1 [hours] 57 [minutes]:

    By the way, check that this value is shown correctly ... The finger at 65 degrees should pop up quickly if you touch the top of this disk after a while of work. This is for additional verification :)

Topic summary

The discussion revolves around concerns regarding the operating temperatures of M.2 SSDs, specifically a SATA SSD at 33°C and a PCIe SSD reaching 71°C. Users express that while the temperatures are not excessively high, they could be improved. Recommendations include using the Kingston SSD Manager for monitoring, ensuring proper ventilation in the computer case, and verifying temperature readings by touch. The general consensus suggests that while 71°C is on the higher side, it is not immediately alarming, but users should aim for lower temperatures for optimal performance.
