We took note of the drive’s temperature during some of our benchmarking runs. The Kioxia Exceria PRO G2 uses a Silicon Motion SM2508 8-channel controller, which has been designed to offer high performance with low power consumption, negating the need for the large heatsinks seen on the first batch of Gen 5 drives.

The Exceria PRO G2 has what looks like, at first glance, to be a strip of copper built into the product label. We tested it sitting under the passive heatsink that comes with the Gigabyte AORUS X670E Xtreme motherboard we used for testing.  Under benchmarking, the hottest the drive got was 36°C when the drive was running the CrystalDiskMark 8 Sequential QD1-32 T1 Write test. For the majority of the testing, the drive averaged 31°C, which, for a Gen5 drive is very impressive, while the 4K-based tests averaged out at 27°C, another impressive figure
