Phison PS5031-E31T 2TB Technical Preview (E31T Controller)

We took note of the drive’s temperature during some of our benchmarking runs.

The design of the PS5031-E31T us a 7nm process which allows it to run cooler than the E26 Gen 5 drives we've seen to date. The review sample drive didn't come with a heatsink which comes as a bit of a shock after all the chunky coolers used by previous Gen 5 drives. We used it under the built-in heatsink on our Gigabyte AORUS X670E Xtreme motherboard. The hottest the drive got was 66°C (the drive has a maximum operating temperature of 70°C) when pushed hard during some of the CrystalDiskMark tests, but we didn't seem to suffer from any throttling issues. For the non-4 K tests the drive averaged 59° C while for the 4K-based tests, the average was 50° C.
