High CPU temperature while gaming (G3 3579)

I really worried of my CPU. When I play FarCry5 or other similar game, my cpu became wery hot - 100 degrees.(It is the maximal allowed temperature for my cpu). Cooling have the best perfomance. I cleaned it up not long ago. Both coolers working on their maximum RPM value. Temperature in my room - 25 degrees.
TurboBoost & SpeedStep Enabled.
Do I need to do a thermal paste replacement? I want to use high-end gaming grease Arctic MX-4
