PCIe 5.0 SSDs Using Phison E26 Controllers Seen Shutting Down at Higher Temperatures

There have been multiple reports of PCIe 5.0 SSDs using Phison E26 controllers shutting down after reaching high temperatures during testing. According to ComputerBase (via TechPowerup) numerous SSDs using the Phison E26 controller will shut off instead of throttling after reaching certain temperature thresholds. These include models from Adata, Crucial, Gigabyte, and Seagate. Now in keeping things in context, it should be noted this was seen during testing when not using the stock coolers or being placed under a motherboard's cooling cover or other cooling solution, essentially just leaving said NVMe M.2 type drives exposed without any added cooling. A Phison CTO has previously said in 2022 that future M.2 SSDs could need active cooling and this at least in part seems to be true now.

Just have to say that a number of us have wondered what the threshold for using a Gen5 drive w/o a cooler or motherboard solution is and, well, it looks like nada. These reviewers stated they saw shutdowns within under a minute for read-and-write tests. It varied but more or less about a minute.

I'm glad I stuck with Gen4 builds for now.
