That brings only what if a cooler on it is. Otherwise, you can also leave that off. May be fit

Mostly not, is just too thick and makes no sense anyway, since there's hardly any air to which the heat could be given off. If you really use the M.2 SSD permanently, because so much data is being transferred, then I would put to data management on a NAS or at least a booth computer!

An SSD Mags warm cooling is even counterproductive in this case.

So total nonsense the whole
