I currently have my Intel Core i7-3770K at 4.2 GHz with the stock cooling. I ordered the Corsair Hydro Series™ H110 on amazon.com yesterday and I'm most definetely going to get it till Friday, next week! Which are the highest clock speeds I can overclock my CPU to, without having to change the voltages? I have one golden rule which is to never touch the voltages, no matter what, so that's why I want to keep the stock voltages.
