Benchmarks: Core i7-3770K at 4.4GHz
Noctua doesn't recommend using the NH-L12 on an overclocked chip, but we just couldn't resist. With our Core i7-3770K bumped up to a modest 4.4GHz, temperatures rose close to 88ºC after 15 minutes of a Prime95 stress test. Though, even that's a big improvement over Intel's reference solution.
