Heat dissipation and controller complexity. NVMe controller might be more computationally heavy and so they might emit more heat*.&lt;p&gt;But assuming that NVMe and SATA SSD controllers emit the same energy, it makes more sense that NVMe would be hotter.&lt;p&gt;Think about it. If you throw a ball of high heat meat would it cool faster if it was connected to a large body of water (SSD with its chasis) or a small body of water (NVMe  small piece of plastic that is the NVMe)?&lt;p&gt;Another thing to check if your NVMe either has proper thermal pads placement and&amp;#x2F;or if the air from the front coolers is reaching it.</text><parent_chain><item><author>throwaway8941</author><text>And the much higher temperatures (if your M.2 is an NVMe). Could anyone knowledgeable explain why NVMe tend to get much hotter than SATA under similar conditions? I&amp;#x27;ve been testing mine with not more than 400-500 MB&amp;#x2F;s and it quickly gets to 60°C+, while the old 840 Evo doesn&amp;#x27;t get above ~45°C (running a very similar synthetic workload).
