We took note of the drive’s temperature during some of our benchmarking runs. The Solidigm P44 Pro doesn't come with any form of a physical heat sink and Solidigm claim it has been optimised for thermal efficiency and minimal throttling which seems to be confirmed by our test results.
The hottest the drive got was when being pushed extremely hard during repeated runs of the CrystalDiskMark 8 Sequential write tests where it reached 57° C, 13° C below the stated maximum of 70° C which is a bit close for comfort, but there didn't appear to be any throttling issues.
For the bulk of our testing, the temperature averaged around 36° C, well below that 70° C maximum operating temperature.
