AMD CPU temperatures
65W processor :
We start with our 65W profile, a fairly low power consumption, especially when you consider today’s monsters. This power consumption is intended to simulate small processors with few cores or low power consumption.
On a 7900X, Noctua’s large heatsink doesn’t fall short of the mark, as it always comes out on top at high speeds. Once again, at 66%, the Assassin IV comes out on top, while the Austrian solution comes in between the Dark Rock Elite and the NH-U12A.
105W processor :
Here, our CPU will run at 2.70 GHz constantly and on all its cores. We apply a VCore of 1,030 to obtain a power consumption of around 100 watts. This corresponds to the TDP of a Ryzen 7 7700X.
It’s a pity that the D15 G2’s fans turn so slowly at low power, as we’d be dealing with a real killer. In the meantime, the heatsink shines in its cooling capacities at high speed, but doesn’t fall short at low revs!
Processor at 170W :
Finally, we end with our 170W profile. Here the heat release is higher, and corresponds to the default TDP of the 7900X. Let’s see how our coolings fare!
Mounted on a processor consuming 170W, once again we’re dealing with a formidable benchmark. Other dual-tower heatsinks have higher temperatures.
Summary :
As with Intel sockets , the NH-D15 G2 shines through its low temperatures at high speeds or in high temperatures. Once again, its low fan speed (33%) has a negative impact on performance.
