Should I overclock and how should I go about doing it if i do? I have an Asrock mobo with an I7 3770k on stock settings my cpu cooler is the CM hyper 212 plus. it seems to run very cool in my case the CM Storm Trooper.
If you're asking yourself, the answer is probably no.
Overclocking is done for one of two purposes: the need to push more speed out of an under-performing chip when budget is restrictive, or insanity. I'm in the second group, as are most overclockers 'round these parts.
Can you get good performance out of a stock clock nowadays? Heck yes. Do you need to overclock, even to play intense games? Nope. But it's fun.
I want to be accustomed to overclocking because I will be getting into the hobby of watercooling in the future
Not to question your decision, but I think most people get into watercooling because they're overclocking. There's no need to watercool anything (unless you're going for a specialty silent build or something) without the OCing, IMO.
