It depends. Because NAND flash storage relies on electron tunneling, you actually need high temps for the mechanism to work well. Too much cooling and you'd be increasing the wear levels prematurely. Not sure if this thing is smart enough to know when to kick the fans on and when to keep the temps "high". That is something worth noting though.

Wait! There is commodity hardware that relies on electron tunneling?!

There was even technology announced for self healing NAND flash - drives that could cook itself to 800C to heal worn out cells. Never materialized tho :( https://www.extremetech.com/computing/142096-self-healing-self-heating-flash-memory-survives-more-than-100-million-cycles https://www.extremetech.com/computing/142096-self-healing-se... https://hardware.slashdot.org/story/12/12/02/2222235/self-healing-nand-flash-memory-that-can-survive-over-100-million-cycles https://hardware.slashdot.org/story/12/12/02/2222235/self-he... https://ieeexplore.ieee.org/document/7524803 https://ieeexplore.ieee.org/document/7524803

I found this here that says lower temperatures are better for storage but higher temperatures are better for writes. I'm not sure how accurate that all is though
