"We give you a quick look at overclocking the Intel Core i7 920 processor that runs at a stock speed of 2.66GHz. What do you need in terms of cooling when you bring it up to 3.8GHz with at 1.35 vCore? You are not using the stock heatsink for sure.

... This is one of those subjects that needs to be covered but to put it simply we don't need to take you through 10 pages of text and ads to get our point across, so we are not. A quick video and some explanation is all that is needed and we will follow up with a chart so that you can see all of the data we are referring to on your own desktop."
