Top Tier CPU Air Coolers Q3 2015: 9-Way Roundup Review

*Note: When the cooler has two different fans, the fan speed of the faster fan is recorded.
We should start by noticing that one should be extremely careful when reading the performance charts. Even though some of the coolers are of similar design or size, their performance differs greatly. Similarly, coolers with similar thermal performance may have great differences in size, acoustics and or price.
Without a doubt, the grandest example of this warning is the Okeanos. Reeven's offering outpaces nearly every other cooler, comparing directly with Noctua's and Cryorig's finest, when tested at our maximum load and has the best average absolute thermal resistance. However, this is not due to excelling technology or design. On the contrary, the Okeanos is simpler and smaller than most of the coolers in this review. This achievement is simple brute force through high speed fans, which places the Okeanos far behind any other offering on acoustics.
Not unexpectedly, the thermal performance charts are being led by the Noctua NH-D15, the Cryorig R1 Ultimate and the Phanteks TC14PE. These are the best coolers of the most renowned manufacturers, so one would expect interative designs over time to yield benefits. The performance differences between these three offerings, thermal and acoustic alike, are very small. Raijintech's Tisis is the surprise of this review, with similar thermal and acoustics performance to that of the best coolers. The Tisis also has the best low load performance, where the charts shift greatly.
The Dark Rock Pro 3 from Be Quiet! offers lower noise levels but falls a little behind on thermal performance. Not the same can be said about Deepcool's offering, the Assassin, which does not match the thermal performance of the best coolers but is neither quieter nor notably cheaper. The performance gap is rather small but the Assassin is at a disadvantage. The Grandis falls even further behind in terms of thermal performance while the noise levels are similar, but SilentiumPC designed it to be more budget-friendly than other offerings, not to compete with the elite on terms of raw performance. Thermalright's Macho Zero is also an inconsistency in this review, as this cooler is not meant to provide maximum thermal performance and hits the bottom of our absolute thermal resistance charts. On the other hand, the Macho Zero paired with the TY147A is by far the quietest cooler in this review, being whisper-quiet even while the fan is spinning at maximum speed.

No it isn't. The mounting mechanisms on these higher priced sinks are, as, had you read the article, solid. If you are missing an arm and wanted to mount a 100$ heat sink in your 25$ case, you might care about the weight, in which case, the manufacturer's website is a one armed lazy click away.Schickenipple - Monday, July 6, 2015 - link
Cheaper still, at under $50, is the ZALMAN CNPS9500A. I use it on almost every build due to it's all-copper design and razor thin fins. I can keep the fan on the lowest speed without my Core i7 going over 40 Deg. C under load. It's silent no matter what I'm doing.My only complaint is that the fan is not PWM. Quibbles.

The only thing I haven't liked about Zalman, is that the fans they use in their heatsinks aren't exactly the quietest and are usually not easily swappable. At least, not when compared against manufacturers like Scythe and Noctua.Nfarce - Monday, July 6, 2015 - link
I have the 9700LED variant of that design for my old Core 2 Duo E8400 build. It does okay for medium overclocks (running my 3.0GHz E8400 at 3.4GHz), but that was about it. And considering I paid $55 for it back in 2009 when I built that rig (about $60 in today's money), it wasn't exactly a cheap option. I would have spent a little more for a better cooler so I could get a higher overclock, but the new Sandy Bridge chipset was coming out soon and I decided to just keep it as a backup rig.Eidigean - Monday, July 6, 2015 - link
The conversion from Euro to Dollar for the Reeven Okeanos is incorrect. 60€ != $54. 60€ == $66. I think you divided instead of multiplied.GeekTech - Monday, July 6, 2015 - link
I just want to mention that the Cryorig R1 Ultimate CPU Cooler that you listed and said was currently available only through a foreign store registered in Amazon.com that ships from Korea is currently being sold at PC Case Gear here in Australia for AU$89 (US$66.82).Link: https://www.pccasegear.com/index.php?main_page=pro...

I would have liked to see the Noctua's real arch nemesis included in this shootout, the Thermalright Silver Arrow. Crushes the Macho Zero. I have a Silver Arrow on my i7 4790k running seti@home, and it owns.Innokentij - Tuesday, July 7, 2015 - link
The Phanteks PH-TC14PЕ is a better cooler using noctunas own fans on it and even better if u add AF140 fans to it . Is why i took it over the Noctua for myself.http://www.xbitlabs.com/articles/coolers/display/n...

There is an updated version of the noctua: http://www.noctua.at/main.php?show=productview&...Eidigean - Monday, July 6, 2015 - link
It's not so much as updated, as it is an off-center version of the same NH-D15. I would need the NH-D15S that you linked to on my MB as the former would hit my GPU in the first slot. I was considering modifying the D15 to move it up and away until I saw the D15S. A good link none the less.
