AMD Ryzen 5 & 7 CPU Cooler Round Up
Thermal Testing
In this review, we have tested our coolers in a room temperature controlled environment and tested each CPU cooler with their stock fan configuration with their fans running directly from our system’s power supply at both 12V and 7V (using fan speed reducers).
Each cooler will be tested on Windows 10 using OCCT to provide a heavy CPU load for half an hour, where we will use Ryzen Master to record CPU temperatures throughout testing. The highest measured temperatures are recorded on the graphs below.
Any CPU cooler that reached 70 degrees automatically failed our thermal test, though it is worth noting that no coolers reached this high heat threshold unless we overclocked our CPU.
In our stock tests, we used 2666MHz memory, the highest that Ryzen officially supports, with our overclocked tests running at 3200MHz to provide more stress on the system.
Stock Settings
At stock settings, our results are unsurprising, with the R5 1500X’s Wraith Spire Stock cooler sitting at the bottom of the graph while aftermarket coolers quickly rose to the top.
We can see that at stock settings that all AIO liquid coolers perform similarly, with temperatures of between 43 and 46 degrees, presenting better results than both the Noctua NH-D15S and Cryorig C7 that we have also tested. All of these coolers easily passed our thermal test when fans were running at 7V, providing a quiet operation in all cases.
Overclocked testing
When overclocking this CPU we bumped this CPU up to 3.9GHz using a core Voltage of 1.4V and a SoC Voltage of 1.1V, using 3200MHz memory to provide more stress on the platform.
Here we see our AIO liquid coolers differentiate themselves from each other, though the largest difference is only 5 degrees when moving from the NZXT X62 with fans at full speed to the Cooler Master MasterLiquid 240 with fans at 7V.
All of the CPU coolers that we used passed our overclocked R5 1500X test, though the Cryorig H7 at reduced fan speeds only barely passed this test with a load temperature of 69 degrees. With results that are this close to the thermal limits of Ryzen, we would recommend a larger air cooler for overclocking, especially if your room is frequently over 20 degrees.
