Noctua NH-U14S Testing:

Testing of the NH-U14S will be accomplished by installing the cooler into the test system case. Most systems are built and mounted into a sealed (relatively) chassis as opposed to a test bench, so this method will be used to generate the idle and load results to give a real world view as to the cooling performance from a system listed below. Of course, your results may vary by several degrees due to case design and ambient air temperature. The CPU load is generated by Prime 95 version 27.9 for a period of two hours, with a cooldown period of one hour after the computer has returned to an idle state. Real Temp 3.70 is used to log the temperatures with the highest and lowest averages across the four cores of the Core i7 4770K test CPU. Ambient temperatures are kept at 24 °C during the testing to minimize the effect of temperature variations. Each cooler is tested with the manufacturer supplied thermal compound as delivered.

At idle (stock and overclocked), the Noctua NH-U14S was able to deliver temperatures consistent with the highest performing air coolers in this comparison field, which contains coolers costing much more. Looking at the stock load results, the NH-U14S does a fine job of removing the thermal load generated by the hot-running Haswell processor and keeps the temps within two degrees of the liquid cooled AIO (All In One) Nepton 280L. When overclocked, it is only three degress higher than the 280L, and still well below the thermal danger zone. And it is close, very close, to the performance of the much larger D14.
