Primary composite sensor, about 22 C ambient, active cooling unless noted, Intel Core i9-12900K on Asus ROG Maximus Z790 Hero, drive prefilled to 50% and tested as a secondary device. The review does not say if the 2TB sample had a heatsink and calls it the bare comparison point for the 4TB. KitGuru logged 46 C in short runs under a motherboard heatsink, and techtest.org reported over 100 C in a CrystalDiskMark pass and does not state the cooling, which are different methods13Reviewtomshardware.com/pc-components/ssds/samsung-9100-pro-ssd-review/3Read 14 October 20264TB bare drive 71 C and 4TB with Samsung's heatsink 47 C, same test bench and method as the 2TB
