Seagate FireCuda 540 2TB Gen 5 SSD Review

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

Seagate's FireCuda 540 comes without any form of heatsink and therefore must be used with a third-party heatsink or a motherboard cooling solution to stop the drive throttling back or worse still thermally shutting down if it gets too hot. We did our testing using the built-in heatsink on our Gigabyte AORUS X670E Xtreme motherboard.

During our benchmarking runs, the hottest the drive got was 57° C during CrystalDiskMark 8 Sequential QD1-32 T1 Write test, which is only 13°C away from the maximum operating temperature of 70°C, a wee bit too close for comfort. For the non-4 K tests the drive averaged 48.10°C while for the 4K-based tests, the average was 45.41°C.
