Those M2 MVNe SSD's like to run hot, they perform faster if they are a bit toasty, over-cooling them actually degrades performance.
Oh good lord... that one again.

I've watched this one go back & forth in my gamer threads so many times I just wanna

Yes, there's a technical dissertation which says that
certain NAND FLASH suffers less wear if operating in the JEDEC-spec ~40 degrees C range
at the time of erasing/writing. This study was done under lab conditions which bear no resemblance to real-world usage, and
those results have no material relevance to the NVMe drive's performance overall, nor the real-world implications of running the whole SSD at elevated temperatures, which are poorer cell self-healing and long-term data retention as well as the usual thermal expansion/contraction failures associated with BGA devices and microscopic traces on PCBs.
The dissertation also suggests that read performance is degraded, so any benefit of keeping the NAND FLASH hot is lost in the overall performance balance, and completely ignores the fact that the primary heat generator here is the controller chip, and it is the part likeliest to fail under heavy load, thermal or otherwise. Even if you do give
some credence to the "improved performance" interpretation of the dissertation, all you have to do is think aboot it for a moment to realize that attaching a single common heat sink, as these solutions are normally provided, will improve this condition by equalizing the temperature across the entire device, keeping the NAND much closer to the JEDEC-spec ~40 degrees C range. It will also also help normalize the temperature of the entire SSD, mitigating the above-mentioned thermal expansion/contraction failures associated with BGA devices and microscopic traces on PCBs.
Well, in principle anyways.
TL/DR: In my opinion, no there is no "magic of the SSD" thing going on here which works contrary to the basic engineering principle that in general, cooler electronics will be more likely to live long and prosper. This is just another case of some people reading some scholarly work and taking away one single soundbyte worth of information and running with it.mnem
