Applying a substantial overclock to the CPU creates a tough battle but H80i GT does an admirable job with the fan speeds set to maximum. The cooler appears to come into its own by stepping above the performance of the best air coolers on the market. Unfortunately, having the fans set to default with such a big overclock only results in high temperatures – which is understandable at just 1400RPM. For this kind of scenario we need at least 1800-2000RPM.
