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

| Core Temperature, Constant Thermal Load |

*Note: When the cooler has two different fans, the fan speed of the faster fan is recorded.
**Note: Some of this review's PWM fans will not start if simply powered from a 7 Volts power source. Electronic supervision is required to start the fan and then reduce the voltage down to 7 Volts, or a PWM source.
Reducing the fan voltage down to 7 Volts shifts the thermal performance charts a little but brings all of the coolers down to virtually inaudible levels. The sole exception is the Okeanos, which definitely improved vastly in comparison to having its fans running at maximum speed, but remains audible.
With the Okeanos losing its advantage of brute force, the Noctua NH-D15 and the Raijintek Tisis now lead the thermal performance charts, closely followed by Cryorig's R1 Ultimate. The Phanteks PH-TC14PE is a bit more complicated, displaying that it can do much better at lower loads than with high loads, hinting that the airflow of the fans is simply not enough for this design to cope with very high loads. Be Quiet!'s Dark Rock Pro 3 is now showing thermal performance comparable to that of the aforementioned coolers, especially when the thermal load is low. Still, the Dark Rock Pro 3 technically loses its acoustics performance advantage. It may be dead-silent, with our equipment unable to record anything about the room's noise floor level, but the rest of the coolers are virtually inaudible as well.
The Thermalright Macho Zero is at advantage in these tests, as the cooler is optimized for low airflow situations. With the TY147A at a dead-quiet operating level, the Macho Zero offers very good thermal performance, especially at lower loads.
The two coolers with the worst overall thermal performance at this test were the Deepcool Assassin and the SilentiumPC Grandis. As far as the Grandis is concerned, the company will definitely not worry about their product not being able to compete directly with the best air coolers available, as it can still offer very good performance for the price of the cooler. The Assassin on the other hand fails to compete as well as it should, falling behind all other similarly sized products and even behind the Grandis during most of these tests.

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.
