I concur, my CPU has a TDP of 65W but getting all threads spinning in a loop jumps the power to more than 120W, and CPU quickly rising to max junction temperature (95C) for a minute or two until the the system resets :-( I installed thermald to manage temperatures, but it seems crap firmware/Linux design that lets system run at unreliable and life shortening temperatures without some user-side daemon running and throttle CPU speed to keep things from overheating. -- Tixy
