Because they are blindly following an overclock guide that gives them bad advice, or they dont know what prochot/tm are for either. And neither has anything to do with performance or stability, they simply protect the cpu once it reaches its maximum safe temperature/tjmax.
For example, TJmax is 100C on my i7 950. At around 99-100C, THERMAL MONITOR kicks in and reduces frequency first, then voltage second, to prevent cpu from overheating. If disable thermal monitor in the bios, the cpu will not reduce frequency or voltage and likely exceed tjmax.
I dont think bioses will let you disable Prochot out signal, so when you disable prochot in bios, it only disables sensory component of prochot, but that isnt a good idea either.
But bottom line if you disable either, it will not help you overclock, all you have done is prevent the cpu from being able to properly protect itself at tjmax, ie 100C on my cpu. At 15-20C beyond tjmax, 115-120C, the cpu is supposed to shut itself down in a final attempt to prevent permanent damage, if you could turn off prochot completely in bios, it would remain to be seen if cpu turns itself off, I can tell you what happened to mine...
I am rge on xtreme, during temp testing, I disabled both prochot and thermal monitor while temp testing a delided (removed IHS) E7200, surface temp was little over 100C, core temp was around 130C and rising quickly as the core melted (link to pic of melted core). So much for that cpu protecting itself.http://www.xtremesystems.org/forums/showthread.php?p=3077591&highlight=E7200#post3077591
Although people do disable prochot and thermal monitor, they typically wont have a problem unless heatsink comes loose or something like that.
