Performance (A10-6800K 100W)

For today's testing, we're using an A10-6800K 100W APU rather than the 125W FX-8370 processor with which it ships. This will better indicate how the Wraith will perform with AMD's upcoming 95W Zen chips and allows us to make closer comparisons with heatsinks previously tested on our Intel Sandy Bridge based small CPU cooler test platform.

Red box indicates insufficient cooler (thermal throttling).

The Wraith performs surprisingly well on our test platform, keeping the thermal rise below 35°C throughout most of its range. Cooling proficiency drops off gradually as the fan speed is reduced with no substantial reduction until the jump from 30% to 20% speed. However, it's already fairly quiet at this level, it the 15~17 [email protected] range. At 10% speed (about 1000 RPM), it finally fails as the CPU clock speed begins to fluctuate, frequently throttling down to 2.0 GHz.

The cooler sounds miles better with our reference 92 mm fan but it fails miserably at replicating the performance of the stock fan. The difference is startling with the Nexus fan producing temperatures more than 10°C worse at similar noise levels. It's easy enough to swap the fan but it would seem that a typical case fan is not well suited for this heatsink.

Comparison Tables

For a direct comparison, two of our favorite small aftermarket CPU coolers were re-tested on the same A10-6800K system. The Noctua NH-L12 is one of the best coolers on the market for smaller systems, shipping with both a 120 and 92 mm fan; This is somewhat unfair, so it was tested in single fan configuration, such that the cooler stands 66 mm rather than 93 mm tall. The Scythe Shuriken 2 is a sleeker 58 mm high cooling solution with only a slim 120 mm fan; We've used it to great success in low profile cases like the SilverStone FTZ01 and RVZ02.

Surprisingly, the Wraith stacks up quite nicely, edged out by a few degrees by the NH-L12 with its larger 120 mm fan installed. The Wraith beats the Big Shuriken 2 by a similar margin and its performance holds up much better at very low noise levels.

Using previous results from our Intel-based small heatsink test system and our even older Athlon II test platform, the relative performance of the Wraith and a pair of older Phenom II stock coolers has been estimated below:

The Wraith's place on the chart is similar to that of tower heatsinks equipped with a 92 mm fan like the SilverStone Argon AR02. The older stock cooling solutions are near the bottom, in the same league as anemic low profile models like the Scythe Kozuti and Phanteks PH-TC90LS.
