Lm-sensors weird readings

I get weird readings with lm-sensors in my laptop , does anyone have any idea what is going?

sensors                                                                                          ✔  57s 

What is weird about it?

the critical , high and low values seem like 2^n defaults or something?

maybe

I thought you where concerned about the actual reported readings rather than the given ranges.

That looks like 0 Kelvin to me. Curious.
And the high is 2^16 - 1 Kelvin.
