Sound performance is good too, though it’s into second place. The Noctua NH-D15 takes the crown here despite being a two fan cooler.
When you look at the difference, in reality it’s probably too close to call, though we control our testing very carefully, we wouldn’t call anything under one decibel truly noticeable. For overclocking we used the Asus Rampage V Extreme Motherboard 6 core overclock pre-set and manually set the DDR4 to 2666Mhz. We save our own profiles for stock and overclocking, ensuring correct test results.
The Noctua NH-D15 and the Cryorig R1 Ultimate beat the H5 to the top spot as you would expect. This is where the two fan coolers should really come in to their own. The H5 still has some excellent performance though when pushed we got to 98 Degrees. We need to stress, the “Stress” test we use is intensive, so it is going to work these heat sinks well. Only the Noctua NH-C14S is behind the H5, a capable cooler but a one fan cooler also.
The Noctua NH-D15 is our top performer for overclocked sound performance, you can see why it’s our favourite flagship cooler, but the H5 is an excellent second place.
