We took note of the drive’s temperature during some of our benchmarking runs. The well-designed passive heatsink works pretty well. During our benchmarking runs, the hottest the drive got was 61° C during CrystalDiskMark 8 Sequential QD1-32 Write test run. For the non-4 K tests the drive averaged 48.15° C while for the 4K-based tests, the average was 44.44° C. The standard T700 averaged 39.72° C for the non-4 K tests and 32.72° C for the 4K-based tests. Bear in mind that keeping the standard drive cool in our test rig was the serious chunk of machined aluminium (weighing in at 150g) that Gigabyte use as a heatsink as well as two thermal pads in the X670E AORUS Xtreme motherboard we use.
Just to show why you need cooling for these Gen 5 drives, we tested the T700 without any form of cooling. The drive has been designed to start throttling back if it goes above 81° C and will thermally shut down at 90° C. We tried running the ATTO benchmark and withIn a couple of minutes the drive hit 81° C and sure enough, started to throttle back almost instantly, reads dropping from 9GB/s to 5.9GB/s and writes falling from 11GB/s to 6.3GB/s.
