First off, we started with LGA1366 and a Core i7 920 at stock speed. Here are the results:

As we can see, the NH-D14 shows excellent results at stock speed, both at idle and under load, and keeping the hot i7 920 under control. Sitting atop the performance heap, the NH-D14 is already 2°C cooler than the nearest competitor at load.

Things are off to a great start, so let’s juice up the voltage and overclock this chip and see what happens.

Again we have similar results, with the NH-D14 leading the pack by a couple of degrees. Notice, however, that although it holds that same idle temperature, it pulls away under load, establishing a lower Delta (temperature difference) as its cooling efficiency becomes apparent.

Let’s now take a look at the LGA1156 results:

More the same here, except that the NH-D14 manages to pull ahead even further, increasing its lead by 3°C under load at stock speeds.

And when we overclock:

Wow. Not only does the Noctua NH-D14 continue to easily be the top performer, but it pulled away from the nearest competitor even further and stretched its lead to 4°C at load. That is outstanding. The more it’s pushed, the better it seems to do. And not only did it manage to handily beat every single other cooler, it’s running near silent and allowing us to push some very good overclocking results on our LGA1156 chip. Clearly, if you optimize your voltages, you could push it even further and easily hit the magical 4.0GHz for 24/7 use.

The fan noise is quiet overall, though not as quiet as the Noctua NH-U12P due to the 140mm fan running at higher RPMs. This is not to say it’s loud; far from it, and it will be inaudible inside your case. Noctua fans are renowned for their low noise levels, and the NH-D14 is no exception. Normally top air cooling performance means louder noise levels, but in this instance that’s not entirely correct; top performance results in slightly higher noise, but it is still very quiet overall, and utterly impressive when compared to other top cooling fans that are indeed loud.
