Re: easy done
an old AMD system I had was fanless for a very short while
It actually killed the CPU? Or do you mean without any heatsink at all?
I got called in once to a system that "kept crashing". Took the lid off, spotted the fan not turning, unwisely touched the heatsink and my finger sizzled.
It worked OK until the heatsink got some way above boiling point. At which point the CPU went off the rails and the system wedged. Which gave it a chance to cool down so it worked again until the user next made the CPU try to do some real work. (Booting was/is hard-disk limited, the CPU idles most of the time waiting for seeks to complete).
