We took note of the drive’s temperature during some of our benchmarking runs.
Klevv's CRAS C910 comes with an optional stick-on full-width aluminium heatsink, using this in conjunction with enhanced thermal management (thermal throttling) to keep the drive thermally stable. We did all of our testing with this heatsink in place. The hottest the drive got during our testing runs was 62° C during CrystalDiskMark 8's Sequential Write tests. It averaged 54° C for the bulk of the testing with the 4K tests averaging 49° C.
