Experts can test and tell us if this CPU consumer process is due to mining or to the autobet feature it self (bugs, not well-coded ...).
That is a bug from the auto bet feature you've used. Can you tell us what is the name of the auto bet you've used?
Ther are possible happen that the cause of your CPU becomes heat is, heavy loads memory, airflow issues, and system cooling failure.
Actually, that is normal to the CPU that will heat, that was designed to run a high temperature. If you have doubt on the auto bet you have used or installed in your PC, you can uninstall them to have free space in your PCU's memory.
