We took note of the drive’s temperature during some of our benchmarking runs. The hottest the heatsink version of the Black SN850X got was when it was being pushed very hard during the performance stability test when it peaked at 64° C which is 21° C under the maximum operating temperature. The drive averaged 38.8° C for the remaining tests which is comfortably below that maximum operating temperature.
