As a traditional heatsink/fan, the HE02 delivers rather poor performance in relation to its size. With one of our 140 mm reference fans it produced a CPU thermal rise of 42°C~50°C. In comparison, elite coolers easily produce a result of 40°C or less with only moderate fan speeds. Adding a second fan garner predictable improvements of 2~3°C at higher fan speeds and 4°C at low speeds. Our sample emitted an intermittent clanging sound with one fan and the problem was more pronounced with two. It was steady enough to actually affect the dual fan noise measurements, making them slightly higher than usual.
The noise generated caused a prominent tonal peak with a frequency of approximately 950 Hz, a significant departure from the smooth, broadband profile we typically see with the Noctua NF-P14's. This won't be an issue for users who use the HE02 as it was intended, as a fanless heatsink.
After testing we took a look at the thermal compound left behind by the HE02. The branch-like pattern is indicative of suboptimal contact between the heatsink base and CPU heatspreader. Elite coolers leave behind a very faint smudge of TIM. The physical design of the HE02 exacerbates this issue; due to its odd shape, the distance between the center of the body of the fans is very large, diminishing their ability to exhaust the radiating heat.

With one fan, the HE02 placed a few degrees behind the Phanteks PH-TC14PE, a dual tower heatsink which isn't really optimized for single fan operation.

With two fans, it was again, a step or two behind the more dominant dual fan heatsinks.
