”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.”
