We're not considering fire risks here. Once a system reaches the upper, and sometimes lower, extreme of that system's rated range (which will be different per system, and not something we can throw in the OS), the EC, the PMC, the MC or similar system will shut down the system on most consumer hardware, unless the user has explicitly disabled it, which isn't possible without flashing your own firmware on many systems. -- John M.
