Well, the only insight that you need is: you can write a tight loop that will 'burn' that computer in any programming language. I've written scripts in Python that take 100% CPU time. The only thing stopping the computer from burning itself to a crisp are the OS (not the language the program is written on) and the firmware (most BIOS these days have a setting to auto-shutdown if core temperature goes beyond X value).
