Review: Noctua NH-D15 G2

Intel CPU temperatures

65W processor :

We start with the 65W profile, a rather low power consumption, especially when you consider the basic consumption of this 13600K. We’re here to simulate the power consumption of small processors with few cores or low power consumption. In theory, everyone should do well!

Température 65W

Turning now to temperatures, we note that the Austrian brand’s NH-D15 G2 performs very well at its highest speeds. However, as soon as its fans reach 500 rpm, temperatures rise again. With a delta of 32.2°C, this model is on a par with the NH-U12A.

125W processor :

Here, we take our readings on a Core i5 13600K whose power consumption reaches 125W, the baseline for this processor. This corresponds to the processor’s prolonged power consumption.

Températures 125W Intel

With a power consumption of 125W, once again the NH-D15 G2 comes out on top when its two NF-A14x25r G2s are running at 100% and 66% speed respectively. Under these conditions, it performs very well, matching the Assassin IV at medium speed. However, with the increase in consumption and heating, it is now slightly ahead of the NH-U12A.

170W processor:

Finally, we end our series of readings with our Core i5 13600K, which consumes 130W. For this, we push the frequencies a little further, as well as the VCore, which now rises to 1.270V!

Températures 170W Intel

With a power consumption of 170W, even if the NH-D15 G2 can’t keep up with our processor’s load at low speeds, it still far outstrips its rivals. In these conditions, the Assassin IV is left out in the cold, as are the Dark Rock Elite and the MA824 Stealth, which is in trouble from mid-range!

Summary :

When it comes to temperatures on our Intel platform, Noctua’s NH-D15 G2 performs particularly well at its highest speeds. As we’ve seen, once its fan is running at full speed, nothing stands in its way. The Assassin IV puts up a good fight at mid-range… However, once mounted on our 13600K consuming 170W, it’s left in the dust. On the other hand, the Achilles’ heel of this model remains its high temperatures at low speeds, the fault of slow fans in these conditions.
