This question is asked over and over and over and over and over....

There is a reason we have stickies in forums...please do a little searching before just posting questions.

Researching a little would tell you that 5ghz really isn't something that is sustainable and degrades the chip due to voltage increase.

An H80 and the watercooled rig in that video are worlds apart in cooling, I do hope you understand this. That being said, I'm not sure why you linked that YouTube video to your post since it isn't even remotely related to what you are asking.
