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.

    <3 Noctua.

    The Noctua, although taller, has the best design. Inverting the fan is pretty smart.

    They also tend to be more expensive. But the cost is worth it in my opinion.

    Yes, they actually do provide far better workmanship and package. First Noctua I bought after Scythe blew me away, though it did cost twice the money.

    Great timing, AT! I was just looking at some low profile HSF solutions for a SFF AMD ITX system I have kicking around. The case I'm using has about 70mm clearance IIRC, so I was looking at the Noctua NH-L9a, but I'll have to see if the other dimensions of the Reeven will work in that space.

    Cryorig's C7 is a good ~100W option as well, speaking as an owner of one. The fan it shipped with did have some PWM noise, but Cryorig's CS was helpful and sent a replacement (which is flawless so far) with minimal fuss.

    I've currently got a c7 in my Node 202 build cooling a 6600k. It barely does the job and after two replacement fans, I've finally given up on the fan side. I still use the base but I've custom mounted a 120mm sp fan to it and have seen much better temps. But still not that great. The L9i could t cut it either, which I had on prior to the c7. I've got a scythe big shuriken rev. B on the way to try out.

    A 6600K with an overclock definitely pushes a C7 pretty hard. It keeps mine under control at 4.0, though stress testing does start to push the thermal limit.

    You guys talking about the AMD A8-6600K or the Intel i5-6600K?
  • 80-wattHamster - Thursday, January 19, 2017 - link

    Good question! Intel in my case.
