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.
Of course, at 65W power consumption, all our aircooling fans manage to keep our CPUs cool… However, this is done at different levels. Unsurprisingly, NZXT’s T120 RGB, which is the least imposing, fares the worst. However, the small disappointment comes from the AK720 Digital, which is closer to the T120 RGB than to the HX6250 and NH-U12A chromax.black at high speeds.
100W processor:
Here, our CPU will run at 3.30 GHz constantly and on all its cores. We apply a VCore of 1.132 to obtain a power consumption of around 100 watts. To simplify reading the graph, we’ve rounded off some values to the nearest integer.
Moving up to 100W of consumption, the situation of DeepCool’s AK620 Digital doesn’t improve. It’s even worse than NZXT’s T120 RGB at higher speeds, despite being half the size. Meanwhile, Noctua’s heatsink dominates the world, keeping our Ryzen 9 7900X below 60°C at low speeds.
150W processor:
Finally, we end with our 150W profile. Here, the heat release is greater, so let’s see how our coolings fare!
Ouch, ouch, ouch, the 150W profile really puts DeepCool’s AK620 Digital to the test. As you can see, the cooler is in check at low speeds, while the HX6250 and NH-U12A chromax.black him nearly a dozen degrees in view at full speed and mid-range. Even the T120 RGB performs better despite failing at low speed.
Summary:
While the AK620 Digital’s structure looks solid on paper, it’s ill-suited to cooling a Ryzen 9 7900X. Indeed, with its Ryzen 7000s, AMD continues to offer multi-die MCM processors. The only drawback is that the CCDs, the dies that generate the most heat, are actually covered by only two or three of the six heat pipes, since they cover the CPU horizontally. In fact, we’re prepared to put a coin down on the fact that dual-tower fans, on the whole, are likely to struggle with this type of CPU.
As you’ll see with the 13600K, the heatsink fares much better with this CPU, which features a monolithic die!
