AMD CPU temperatures
100W processor:
Despite a more violent 100W profile, this still represents the least stressful phase of this protocol. It highlights the performance achieved with compact/entry-level heatsinks.
On our Ryzen 9 7900X, set to consume only around 100 watts, there were no particular heating problems overall. At low speeds, the processor’s temperature stabilizes at around 50°C, which is far from alarming. At full speed, we recorded 47°C, a temperature similar to that of the Liquid Freezer II 280 or the H170i Elite Capellix, for example!
Processor at 150W :
Here, our CPU will run at 3.90 GHz constantly and on all its cores. We apply a VCore of 1.246V to obtain a power consumption of around 150W. To simplify reading the graph, we may have rounded some values to the nearest integer.
At 150W, temperatures rival those of the Liquid Freezer II 240 at its highest speeds. However, at medium speed, it performs similarly to Arctic’s 280mm kit, with less than 70°C recorded on our CPU!
200W processor:
Finally, we end with our 200W profile. Here, heat dissipation is higher. It has to be said that our CPU runs at 4.00 GHz on all its cores, with a VCore of 1.36V! Let’s see how our coolings fare!
At 200W, unfortunately the kit is starting to reach its limits, as it can’t keep our Ryzen 9 7900X cool… Just like the 280mm Liquid Freezer II. However, compared to the latter, it fares less well at high and medium speeds, the fault of a thinner radiator perhaps?
Summary:
Overall, the Pure Loop 2 280 does its job on our AMD processor, but it doesn’t work miracles either. 200W of power consumption seems to be the limit you shouldn’t cross with this kit. So, if you’ve got a big CPU, you’ll probably need to run it at full throttle when your machine gets going!
