Testing Procedure
All testing is done at a room temperature of 22°C (72°F) with a 1°C margin of error. For the AMD test bench, the CPU's 3.85 GHz base all-core clock was obtained using the AMD Wraith Prism cooler with the fan at maximum RPM. Once the all-core clock is verified, we limit the CPU to this frequency under load for the stock tests. That said, all other features are enabled, allowing the CPU to clock down at idle. All tests are run with the CPU cooler's fan pegged at 100% PWM for the base results.
Meanwhile, all coolers are tested at a noise-normalized 45 dBA to demonstrate their performance at an acceptable noise output for the majority of users. As for the overclocked results, the AMD Ryzen 9 3900X has been pushed to 4.0 GHz at 1.22 volts.
Refer to this articlefor a full breakdown of our testing procedures.
The idle test consists of the CPU sitting idle at the desktop for 15 minutes.
The primary load test consists of the Blender BMW render looped for 15 minutes, and the peak temperature is used as the result.
In the final test we use AIDA64's FPU stability test, which ensures maximum heat generation. While it is typically considered an unrealistic workload, it is used to show the overhead a CPU cooler has available in a worst-case scenario.
All these tests are completed three times for both maximum performance and noise-normalized results.
