This is most likely a hardware problem. Could be the fan is not working well, so it needs to run on high, or could be the heat sink to the CPU was knocked loose.

Otherwise try ps -ef to see if there are any processes running that are causing your CPU to overheat.

Check if the CPU frequency scaling is working properly. There are variety of ways to monitor that, but you can quickly check it by typing in the terminal:

cat /proc/cpuinfo | grep -i "cpu mhz"

In idle or low load, the frequency of the threads should be lower than the maximum (in your case lower than 2100 MHz).
