Computers are pretty auto when it comes to this. However,
there's a limit. Once it reaches that limit, the processor will
overheat and it will just shut down or force restart.
Yes, you can install more fans to lighten the burden, but the best
is you upgrade your hardware.
To make a computer do such intensive work... your hardware
certainly just passed the requirements to use a program or you
simply have too many things to overwork a computer.
