Please note that if you're seeing higher temperature readings with SSD SMART, and if it's a 3D NAND SSD you're using, it is normal and part of the result of elevated performance. Compared to the 2D NAND Flash, 3D NAND comes with LDPC for better error correction, endurance, as well as thermal throttling ability.
