Benchmarks: Core i7-3770K at 3.5GHz
On a stock-clocked Core i7-3770K processor, all of the aftermarket coolers in our line-up run at comfortable temperatures. Two gargantuan air coolers - the SilverStone Heligon HE01 and Phanteks PH-TC14PE - lead the way, but there's very little separating the rest of the field.
Cooler Master's Eisberg Prestige 120L was tested on a cool winter's day and does a decent-enough job of keeping the Core i7 chip running at below 65ºC under extreme load. A stock-clocked chip clearly isn't enough of a challenge.
