100% CPU Usage and High Temp

Hi, i've got a Ryzen 7 7800X3D CPU and when im loading a new world it goes to 100% usage, which isnt too much of an issue but my CPU temprature is sitting at an average of 90 degrees which is the problem, even wiuth the cpu at less than 50% usage my temprature is still 90, does anyone else have this issue?

my pc has crashed around 5 times because of this
