We took note of the drive’s temperature during some of our benchmarking runs.
The well-designed passive heatsink works pretty well when dealing with a drive where the controller and NAND are running at full speed. The heatsink is backed up by adaptive thermal protection; thermal throttling starts when the drive reaches 81° C and at 90° C the drive goes into protective shutdown During our benchmarking runs, the hottest the drive got was 75° C during runs of CrystalDiskMark 8's default write test. For the non-4 K tests the drive averaged 53° C while for the 4K-based tests, the average was 45.75° C.
