Testing Results, Maximum Fan Speed (12 Volts)

We'll start things off with a look at cooling performance with each cooler's fan running at their maxiumum 12V fan speed.

Average Thermal Resistance

Right off the bat, when it comes to thermal resistance we can see that Noctua's NH-C14S cooler is well ahead of the rest of the pack. Which isn't too surprising given just how much larger it is than the other coolers we're looking at today.

Core Temperature, Constant Thermal Load (Max Fan Speed)

At a 60 watt load - roughly the TDP of most desktop CPUs these days - the results roughly mirror thermal resistance. That said, even the weakest cooler is only 13C over ambient, which is a good result here.

Noise level

Ultimately with every cooler’s fan running at its maximum speed, the Reeven Steropes and the Phanteks TC12LS perform similarly, with the former showing a little better thermal performance despite its low profile 120 mm fan. This small advantage of the Reeven Steropes is being achieved via brute force, as its low profile fan is faster and disproportionally louder than Phanteks’ PH-F120MP. Comparatively, when compared to other advanced coolers that we have reviewed to this date, both the Reeven Steropes and the Phanteks PH-TC12LS can only be compared to the stock AMD Wraith cooler, and even then the Wraith outperforms them both. However, they do significantly outperform standard stock coolers.

Noctua’s NH-C14S is in an entirely different league. The comparatively huge mass of the cooler and the excellent NF-A14 fan offer the NH-C14S a tremendous performance advantage. As a matter of fact, the NH-C14S is a threat to many large tower coolers, outperforming the Cooler Master EVO 212 by a significant margin and touching the performance of the Grandis and the Dark Rock Pro 3, all while maintaining reasonably low noise levels.

    Seems to me a review like this would be a lot more useful if heatsinks were normalized for a specific temperature or noise level. E.g. "The Cryorig produces 40dba keeping our 60w test load at 60c, and 35dba keeping it at 80c", or perhaps "At 35dba, the Noctua cooler kept our test load at 53c. With the Coolermaster cooler, due to the poor quality of the fan we were unable to get a sound pressure reading of 35dba without stopping the fan."

    January 2016, I built a work-horse PC around the i7-6700K + Asus Z170 Deluxe Motherboard, inside of a 3U (5.75" Height) RackMount Chassis and the Noctua NH-C14S (single fan) was about the max height w/o going water cooling route. I run the 6700K @20% OC (4.8GHz) reliably, all the while the Asus MoBo LEDs never getting into the RED range. Noctua fans are warranted for 6years, which made my purchase a no-brainer.

    FYI, the C14S perfectly fits in a Streacom F12C case (even with the fan on top)! I know, I have both and tested both options when I was setting it up!
