Noctua NH-U14S CPU Cooler Review


At Technology X, we test our CPU coolers slightly different depending upon the cooler’s marketed purpose, whether it be for a silent operation or extreme overclocking.  Our goal is to test in a system that has been optimized with our SSD Optimization Guide, however, CPU C State alteration may or may not have occurred depending on the motherboard and BIOS configurations. Additionally, we also try to include links to the benchmarks used in our report so that you as the reader can replicate our tests to confirm that your cooler performs the way it should.

In order to test our CPU cooler, we’ll be running a CPU stress test and monitoring our temperatures using AIDA64, which is a great utility for benchmarking, testing the stability of, and monitoring your system.


To test our cooler, we ran AIDA64’s ‘System Stability Test’ for one hour and recorded the highest temperature reached on any core. We did so at both the stock core frequency of our Intel Core i5 6600K, as well as overclocked to 4.4GHz, and 4.6GHz.

During all tests our ambient temperature was approximately 23C while the cooler’s intake temperature was a slightly warmer 29C.

NH-U14S Performance

Just like most big brothers do, the NH-U14S kicked the NH-U12S out of the ball game, not by much though. The difference between the two is that of a couple degrees. Something possibly to keep in mind when playing with your budget.


Surprisingly, as we compare the the NH-U12S to the NH-U14S, there are many similarities, which are to be expected considering they are basically the same CPU cooler, with the exception of size and design. When it comes to performance, the NH-U12S did perform very well, as did the NH-U14S. We would have liked to have seen the NH-U14S with another NF-A15 fan to see if blew (no pun intended) the NH-U12S out of the water, we can only assume that it would.

Noctua NH-U14S-1

Just the same as the NH-U12S, there is not much we don’t like about the NH-U14S, this is one solid CPU Cooler! For this and more, we proudly award Noctua, the NH-U14S with another Editors Choice Award!

Our spring into summer CPU cooler reviews continue with the Noctua NH-U14S CPU Cooler, the big brother to NH-U12S we reviewed previously. The NH-U14S is the bigger, badder (a good bad if there is such a thing) and down right better CPU cooler than the NH-U12S, at least it should be. We are going to put it through the ringer to find out!
