We took note of the drive’s temperature during some of our benchmarking runs. The WD Black SN770 doesn’t have a heatsink, but there is plenty of empty space on the PCB to allow air circulation around the components. The hottest the drive got was when it was being pushed very hard during the Sequential write test using CrystalDiskMark8,  when it peaked at 60° C which is 25° C under the maximum operating temperature.
