We took note of the drive’s temperature during some of our benchmarking runs. We took note of the drive’s temperature during some of our benchmarking runs. As with the last couple of Gen 5 drives we've looked at, the WD_Black SN8100 we were sent for review doesn't have a dedicated heatsink, although a version with a heatsink is available. We tested the drive sitting under the chunky heatsink of the Gigabyte AORUS X670E Xtreme motherboard, which our test rig uses.

The drive only uses 7W of power when actively writing and 6.5W for reads, and thanks to the controller's 6nm process, it certainly didn't get that hot when being pushed by our benchmarks. The hottest it got was 47° C during a run of CrystalDiskMark 8 Sequential Write QD1-32 T1 test and the default Write test. For the bulk of our testing, the drive averaged 42° C, with the 4K focused tests averaging 36° C, both of these averages a long way from the 85° C maximum operating temperature of the drive.
