Having high temperature on Macbook Air 2017

Hi! I have a Macbook Air 2017. Recently, I am observing that the CPU temperature is really high on idle and its extreme on usage such as watching a video from youtube. It goes up to 100 degrees on usage. What I don't understand is that the fan is not speeding up. I checked with iStat and it was always on low RPM. I resetted my Macbook Air and it is still like that. I changed the thermal paste and it is still like that. What could be wrong ? I am on latest MacOSX Montery

MacBook Air 13″, macOS 12.5

It goes up to 100 degrees on usage.

Fahrenheit or Celsius?

100° C is nothing special for silicon based life forms. Read Keep your Mac notebook within acceptable operating temperatures - Apple Support.

No issue is found according to Diagnostics. I don't know whether this is the best option tho. I know that CPU's are eligible to go up to 100 degree without problem but using it while surfing in internet is not convenient. There is a fan but the RPM is still in lowest even though the temperature is over 90 celcius degree.

Apple Diagnostics will exercise the fan and let you know if it is not working properly:

While watching a simple video from youtube via Safari, these are the temperatures. Fan is not speeding up and lies on 1200rpm.

Yes it is Celcius. However, the fact that this machine was not warming up up until Montery update. I don't understand why the fan is not speeding up.

If Apple Diagnostics reports nothing amiss then your Mac's hardware is working as it should. The fan will work as required to keep it within thermal tolerances.

Enjoy your Mac.
