We took note of the drive’s temperature during some of our benchmarking runs.

The Kioxia Exceria Plus G4 uses Phison's latest Gen5 controller, the PS5031-E31T. The new controller has been designed to run cooler than the previous generations of Gen 5 drives, so it does not need the large active or passive cooling solutions that we saw on the first few Gen 5 drives.

The Exceria Plus G4 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 44°C when the drive was running the CrystalDiskMark 8 Sequential QD1-32 T1 Write test. For the majority of the testing, the drive averaged 38°C, which for a Gen5 drive is very impressive, while the 4 K-based tests averaged out at 33°C, another impressive figure.
