    Any one figure out how the cooling of the Dmve is being accomplished since it can run pretty hot?

    You mean the NVMe 3.0 SSD module? There are cooling pads for those.
    I can imagine that in a closed box without a fan like DMP-A6 those can get fairly hot.

    For electronics the time to live is strongly correlated to the temperature so I can only recommend to get a module with a heatsink attached.
    I hope there is enough space for those inside the box? I suggest to add this advice in the manual.

    Yes nice monkey ssd memory stick is what I am inquiring about, thank you.

    While waiting for the imminent arrival of my DMP-A6 I did some research on sensor readings under Android and discovered AIDA 64 seems to accommodate our needs. Loaded up on my phone it has a section called "thermal" and within that points to a sensor named "ddr-usr" so I'm hoping that will do what we need to keep an eye on SSD temps. Feel free to try it yourselves and report back its usefulness before my A6 arrives.

    Hi, I don't find mine to be hot. I just used a 1tb generic drive that was 40 quid on ebay and plugged it straight in.

    Multiple257 ... Good to hear. There has been some earlier discussion on the SSD getting warmer than ideal so it would be nice to get a reading if that is true or not. I purchased a Crucial CT4000P3SSD8 this afternoon in readiness so hopefully that will work just fine.

    It starts with the subjective feeling what is warm or hot? I don't like temperatures above 40 degrees but above 50 it starts to be really nasty due to accelerated aging.
    That 40 degrees is really warm but at 50 the natural reaction is to withdraw fingers. And 60 degrees it is barely touchable for most. For an SSD not being metal the temperature is probably higher than touching a HDD or Heatsink.

    Begin cautious doesn't harm. The fast SSD in my PC runs without a Heatsink and does not overheat.

    I don’t currently have an SSD installed in mine but I wonder if Eversolo could include a current SSD drive temperature reading on the about page in the settings screen?

    I should imagine that low IO read activities while playing media files should not generate too much excessive heat in the drive while bulk writes during media copying to the SSD would raise the thermal loads that would require dissipation.

    If the current temperature of the drive was easily viewable, those with higher performance drives would be able to keep an eye on the values.
    @mirror - is this possible?

    The box may have a sensor but mostly these are only used in combination with a fan. It will then measure the temperature inside the box but not that of the SSD chips.

    I'm sure SSDs can report temperature..

    Oh yes they do for sure via the drive Health status. :D
    Never seen Health including Temp for M2 SSD though but yes for SATA type SSD's. I guess it is part of the SATA controller?

    I’m sure there are temperature probes built in on most NVMe drives too. I’m not sure they are standardised across manufacturers though. From a brief trawl of the web, the temperature of the onboard controller will usually be slightly higher than the NAND itself.

    Thanks for all the feedback. I too am currently waiting on my dmp-a6 and trying to workout the possible issues ahead. Where would all the heat go in an enclosed environment. But true, a bulk dump of music files would cause the memory stick to heat up quickly. Unsure of the temp difference when just reading a music file. I normally listen to DSD music and that does put a demand on your processor. I wonder what that reading that type of file would do to temp on the dmve ssd stick?

    Heat in a closed box goes to the casing. In this case that casing is fairly thick and will absorb and next radiate fairly well.
