hahaha come grab my 3.0ghz p4

Try to OC in 5% increment until its not stable. My approach is 5%, play a few games and try to notice any glitch or graphic issues if no move on the next 5%, also monitor the temp to be at least lower than 70C .After you done with CPU OC then do RAM OC, play oso with latency and all..

OC'ed a 2.4Ghz to 3.0Ghz (Pentium 4 C or D i forget oredi),  before with stock cooling, using MSI Neo2 board. Nolah it wont explode, you will get glitches or instability long before you OC until fry the CPU. Just monitor the temperature.
