Red box indicates insufficient cooling (CPU throttling).

The A10-7860K stock cooler fares rather poorly on our AMD testbed. It performs adequately at higher speeds, keeping the thermal rise above ambient under 40°C but as the fan speed is reduced, the CPU temperature quickly approaches the point where throttling occurs. The CPU clock speed starts to dip somewhere in the 2000 to 2400 RPM range, reducing the thermal load such that there is only a 1°C difference between the two fan speeds. The lowest stable fan speed of 2400 RPM generates a noise level of 27~28 [email protected] which is terrible compared to most aftermarket solutions.

Red box indicates insufficient cooling (CPU throttling).

At the 27~28 [email protected] level, the A10-7860K cooler runs close to 20°C hotter than the Scythe Big Shuriken 2 and the Noctua NH-L12 with only its smaller 92 mm fan installed. It also trails the more compact NH-L9a by about 10°C. Unfortunately, comparisons at quieter levels are not possible on our testbed due to CPU throttling but I can't imagine it would make up any ground at lower fan speeds. The NH-L9a and Big Shuriken 2 ultimately fail the test as well but only at 15 [email protected] and lower.

Our Intel test chip is capable of hitting much higher temperatures without throttling, allowing us to generate results for the i7-6700 cooler all the way down to its minimum speed. The thermal rise spread is 22°C between maximum and minimum fan speed, compared to just 13°C for the AMD cooler.

The Core i7-6700 stock cooler manages to beat two aftermarket models, the comparably sized Phanteks PH-TC90LS, and the even lower profile (34 mm tall) Reeven Vanxie. The Core i5-4690K cooler is only a few degrees better, so the old copper core doesn't make that much of a difference.

While it's impossible to directly compare Intel vs. AMD as they have incompatible mounting systems, we have estimated the performance based on relative differences with aftermarket models like the Big Shuriken 2 and NH-L12. The A10-7860K cooler is outperformed by the i7-6700 cooler but not by a great deal.
