Experience with an incorrectly heatsunk laptop GPU has demonstrated to me that the BIOS will yank power to the system if it hits 100°C.
Yeah.
Well, in all honesty I'm not sure if it was Linux, the BIOS, or some low-level thermal monitoring circuitry, but yeah, I one minute I was messing around with WebGL and the next minute I got confused about whether I'd forgotten the power cable. (Then I realized I hadn't heard any beeping (this was a ThinkPad and I didn't have the beeper muted) and realized it had overheated.)
