I see, that then is why EK offer heat sinks for your M.2 drives: EK-M.2 NVMe Heatsink - Nickel – EK Webshop
Not really as it doesn't really do anything, but look cool. NAND cells like heat, but the controller doesn't(it starts to throttle when to hot) the only thing needed its airflow to blow the warmth away, just like VRMs. Even the M.2 heat sinks are not needed, and can even trap heat between M.2 and motherboard.
Samsung 960 evo is/was notorious for heating up controller chip, I had it at almost 90c at which time it was throttling like crazy. Position on the MB didn't help any, right under GPU so I had to relocate GPU !!! With this heat sink it never overheats and I was able to move GPU back to first and only x16 PCIe slot.
HWiNFO gives me this about my 860 Pro SSD, so I guess it would give you the same info for an M.2
