Load Test Results

GPU

At full load, the temperature difference between the third-party coolers and the stock cooler was even more apparent. They were all at least 19°C cooler than the stock cooler.

The Sytrin VF1, with its fan set to 3000 rpm, was still the best cooler. It brought the GPU temperature down to just 30.5°C above ambient. However, this configuration was by far the noisiest.

The other third-party coolers were close behind, with both the Thermalright V1 (with two fans) and the Zalman VF900 just 2.5°C hotter.

PCB

The Sytrin with its 92mm Deltan fan was very good at reducing PCB temperature, with the Thermalright V1 close behind when equipped with two fans.

VRM

At load, the Sytrin VF1 surprisingly overturned the Thermalright V1's superiority in cooling the voltage regulator, albeit with only a small lead. In fact, all the third-party coolers were close in performance.

The stock cooler, in comparison, was 14.5°C hotter than the poorest third-party cooler, the Sytrin VF1 with the fan set low.
