We took note of the drive’s temperature during some of our benchmarking runs.
We tested the standard, non-heatsink of the SSD 9100 Pro, sitting under the chunky heatsink of the Gigabyte AORUS X670E Xtreme motherboard we used for testing. The drive has a few design features to combat the Achilles heel of high-end Gen5 drives, being heat generation. The combination of the controller's 5nm process architecture, the nickel plating on the controller, heat spreader label on the back of the drive and Samsung's Dynamic Thermal Guard technology work very well.
The hottest the drive got was the CrystalDiskMark 8 0 fill Read test where it reached 46° C. For the bulk of our testing, the drive averaged 40° C with the 4K focussed tests averaging 35° C.
