WD Black M.2 nvme M.2 Running Hot

Mine is routinely running between 47-51C. The load is not all that heavy. Is this normal? Seems pretty hot to me.

If it’s the older 512GB one that doesn’t seem unusual (e.g. 57C on B35900WD firmware at this post and mine is running 59-60C on B35500WD).

Mine used to run much cooler. Since I’ve added 16 MB of RAM, it is now running ~140 deg. F./60 C… It passes the S.M.A.R.T. test without error and nothing is being logged by WD SSD Dashboard as troublesome.
