AMD CPU temperatures
Processor at 105W :
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.
Thermally, the be quiet! kit offers something quite interesting. In fact, if its fan is running at full speed, the kit is quite capable, and can even compete with larger 360/420 mm kits. However, as the fan speed decreases, we feel that it is penalised by the size of its radiator and its ventilation if we compare it to Cooler Master‘s ML240 Atmos . Yes, at 33%, the Cooler Master kit mills are still running at 900 rpm. Coupled with the shape of the blades, this makes all the difference.
170W processor:
Finally, we end with our 170W profile. Here the heat output is higher, and corresponds to the default TDP of the 7900X. Let’s see how our coolings fare!
With a power consumption of 170W on our AMD CPU, the Light Loop 240 still does just as well with the fan running at full speed. Once again, it’s up there with the big boys… Although Ryuo III maintains a comfortable lead. However, at 66% speed, the kit falls behind the 360/420 mm AIOs that are Corsair’s two iCUE Links. Worse still, at low revs, it can’t keep up with the load on our processor.
Summary :
Broadly speaking, we’re dealing with a watercooling kit that performs very well when you run it at high speed. Its offset mounting on the CPU should seriously help to draw the heat emitted by our Ryzen 9 7900X. However, at low speeds it is penalized by the size of its heatsink or its fans, which don’t blow enough to hold out in these conditions. This is the main advantage of large AIOs: the greater heat exchange surface area created by their large radiator means they are silent, even under heavy loads!
