Using psensor, temp1 reads at around 92 degrees Celsius (and fan spins at around 4000RPM) while lm-sensors' temp1 reading is at 32 degrees.

This is the psensor reading.

This is the lm-sensors reading.

One the one hand 90-100 degrees is very high and my laptop (thinkpad t490) isn't hot to the touch though this may have to do with heat conductance). On the other hand psensor reads 90-100 degrees even when my laptop was off for several hours and my working environment is a bit cold (around 20-25 degrees) making me think that it's not accurate.

Can anyone help me understand if there are any differences between the two (lm-sensor reading vs psensor reading) or if this is caused due to an error?

When you say you run lm-sensors, I assumed you meant sensors, because that is the binary that lm-sensors installs. But in your comment you say you are running service lm-sensors status which is your problem. What isn't included in your screenshot is the timestamp that is also on that line. When I run that, I get:

  Dec 04 10:59:38 redacted-hostname sensors[878]: temp1:        +42.0°C  (crit = +128.0°C)

Notice the timestamp, 34 days ago. When I run uptime I get 34 days. That output you see from service is from the startup logs of the service.
