FTL overheating/turning on turbo boost when it is turned off

I've noticed that FTL AE is overheating some computers (with Vsync and frame limiter on). On Windows I used a program called ThrottleStop to underclock the CPU frequency so that the computer doesn't overheat. On Linux I use the intel_pstate driver and turn on no_turbo. These measure works great with stress testing software as the CPU frequencies will not go above the amount I limit it to.

So when I start playing FTL everything changes. The CPU frequency will be pushed to the maximum available (on Linux I see turbo boost being activated and on Windows I see it go above the one I set to. On windows it might be turbo boosted too but I cannot tell because I'm not the owner of that machine so I don't use it often).

This causes some laptops to overheat as their frames are not high quality frames.

This seems to be a concern as I don't understand why FTL can override CPU settings without super admin/root privileges and seems like a bug.

Any ideas?

Could be whatever software libraries/middleware they're using for the game.
I know that for me, FTL will crash my computer, if I have my browser running, with some flash video (e.g. YouTube) running at the same time in the background.
Also, Windows keeps complaining about my performance being low, and my fan/CPU run hot running this game.
I think it might have to do with my brand/model (Nvidia something-or-other) of graphics card, and buggy drivers.
