Is it worth worrying about 80 degrees on an NVME drive?

Question

linux

I can not catch the cause of periodic heating (according to the sensors utility) on the disk.
#sensors nvme-pci-0200
nvme-pci-0200
Adapter: PCI adapter
Composite: +49.9°C (low = -273.1°C, high = +80.8°C)
(crit = +80.8°C)
Sensor 1: +49.9 °C (low = -273.1°C, high = +65261.8°C)
Sensor 2: +79.8°C (low = -273.1°C, high = +65261.8°C)

And this happens spontaneously, no conditions were caught. And always on Sensor 2 (what are sensors 1 and sensor 2 by the way?).

The iotop values ​​are null at this point. Proc does not heat up at all. In htop, too, everything is at a minimum. Then it cools down to 40-43 degrees.
How to calculate who is heating the disk?
How harmful is it?

UPD. I mark all three answers as solutions. For, probably, a clear answer to this cannot be found without the use of a crystal ball.

Answer 1

And it happens spontaneously, no conditions are caught.

This means that the sensors read the readings crookedly, nothing new.
Even if there was such a temperature, then nothing terrible would have happened. Moreover, there is no such temperature.

Answer 2

If this is a constant temperature - it makes sense to think about cooling the SSD.
And if such a temperature occasionally under load is the norm.

Answer 3

NVME drives connected via the M.2 slot heat up to 100 degrees during reading or writing. The easiest way is to install a radiator. I had the same situation with samsung pro, in idle time 46/56 in operation up to 120 after installing the radiator, the temperature does not rise above 56.
