We Test PCIe 4.0 Storage: The AnandTech 2021 SSD Benchmark Suite

I'm concerned about heat if that little fan goes. I know the storage throttles, but I would imagine 90C+ flash memory is not good for it's long term durability.

I'd like to see a complete fin heatsink that benefits from case flow.

I think the fan and enclosure are a bad idea personally, you'd achieve better cooling on the M.2 cards by leaving it off and having a case that has sufficient airflow front to rear in it. And possibly gluing your own small aluminum heatsinks onto the M.2 cards (which are cheap and easy to do), if they don't come with their own heatsinks.

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.

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 :(

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

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

The enclosure itself is a giant heatsink [1] so I imagine it is fine if you only run 2 NVMe SSDs in this with a bit of case flow.
