The heat dissipation of Central processors for quite a long time is a specific Delta watts. And AMD and Intel are trying with each new generation to produce more energy efficient chips, but top-end models intended for installation in desktop, still requires powerful cooling. In modern processors, which have the function of acceleration, a typical heat dissipation is on the order of 90-140 watts. It does not change. Therefore, it is not so much evolve and cooling system. Today we will compare with each other five of the top coolers where the design of the radiator is made in the form of a letter U. Therefore they are called two-tower. The first products with a similar design appeared for a long time. In its time a big hit was the model of the Thermalright IFX-14. Since its release it took no less eight years. Even now, this cooler can effectively cool any modern processor. It would be in stock mounts for the actual socket. Since then, the twin tower coolers have become the gold standard of air cooling systems.
A comparative test of a two-tower supercooler
Technical characteristics and design features
So, in today’s testing will be held the contest at once between the five water coolers with U-shaped radiator. Detailed models of the NH-D15 and Silver Arrow SB-E Extreme we are already familiar, a hyperlink is given in the table. Therefore, to describe the design features of these devices on the second circle doesn’t make any sense. But the model is from Cryorig and Deepcool stayed in our lab for the first time. They will focus on that. As the decision of the NH-D15S from the same Noctua. Before you proceed to the acquaintance with the coolers, I should note that the Silver Arrow SB-E Extreme in sale not to find. Among two-tower Thermalright devices currently sold is also quite an old model Silver Arrow IB-E Extreme. Unfortunately, her under my hand was not.

Cryorig R1 Ultimate
Cryorig can be considered a relatively new brand on the Russian market of cooling systems. In General the firm was formed in 2013 came from Thermalright, and Phanteks One. So the guys definitely know a lot about making coolers. It is no wonder that the product portfolio of the company includes a decent amount of various cooling systems, including the CBO.
Unpacking the unit immediately shows the attitude of the company towards its customers. Package contents elegant. All the fastening elements related to the different platforms, packaged in different bags. There is a small booklet which detailed the scheme of installation of the cooler. Pleasantly pleased with the presence of an l-shaped Phillips screwdriver and even an item such as alcohol-saturated wipe for degreasing the surface of the cooler and CPU. Additional elements note the system includes two additional brackets for the installation of a third fan and a Y-shaped adapter to combine cables. The compound is called CP9. Unfortunately, no additional information about this interface the manufacturer does not distribute. Syringe will be enough for 2-3 times. In General, for complement Cryorig R1 Ultimate gets a five plus.

The base of the radiator — seven 6-mm tubes. The design of the U-shape was asymmetric. Deplorable with one hand is seriously bent. This was done deliberately so that the cooler does not conflict with the RAM modules. One fan is mounted in between the towers, the second impeller is fixed to the radiator from the outside. Plastic covers are not merely decorative elements, they hold the bracket. Together R1 Ultimate was the tallest cooler among the participants of today’s test.

If we consider the radiator of the cooling system more carefully, you can see a number of interesting features. So, when assembling the R1 Ultimate compression technology was used for the brazing of Nickel-plated plates to teplotransit. In other CPU coolers generally accepted method of crimping, when from a certain number of aluminum fins make up the section, make holes in it the correct diameter and stick it in the preload on deplorable. Here each plate of the radiator split in half and soldered to teplotransit. The manufacturer claims that in this way managed to increase the contact area by 10%. As a result, improved heat exchange efficiency between copper and aluminum deplorably plate. By the way, the R1 Ultimate plates have a trapezoid shape. Plus the output of the air flow they are equipped with additional grooves.
Design features Cryorig R1 Ultimate
The second technology used in the R1 Ultimate, is called the Jet Fin Acceleration System. Due to the separation of the plates in half, one part of the section of the radiator got 42 aluminum elements 0.4 mm thick with intercostal distance of 2.4 mm. the Second part of the section consists of 53 plates with a gap of 1.8 mm. Personally I have never met such a non-trivial layout of the radiator fins.
Design features Cryorig R1 Ultimate
Finally, here are deplorable soldered to the bottom of the radiator at different distances. So, the fourth telotroch is located closest to the base. According to engineers Cryorig, this method is most effective when taking heat from the CPU.
Cryorig R1 Ultimate
To install R1 Ultimate CPU there is no need to remove the fan, placed between the sections. L-shaped screwdriver easily fits between the grooves of the plates. The fasteners in their design is very similar to the system from Deepcool. As a result, the installation process for every socket is a couple of minutes. Simple, convenient, safe.
As I said, some of the cooler covers the next two slots to install RAM. In the end, to the ports of the DIMM modules can be installed with a height of 30-35 mm. This is the only restriction R1 Ultimate. The cooler is massive, but standing closer to the expansion slot (in the case of GIGABYTE GA-X99UD7 WIFI — PCI Express x16) does not overlap.

The base of the device has a perfectly smooth surface. But polishing to a mirror state of not. Nevertheless, the imprint of the thermal paste is uniform. Testing was performed with a processor Core i7-5960X. This is the largest area of the chip, heat distribution the cover is fully in contact with the sole. With the use of small processors (e.g., the item has been added), it is likely that contact will be not all seven teplorulon.
The Base Of The Cryorig R1 Ultimate
Complete with two R1 Ultimate 140mm XF140 fan. Information about these 11-blade choppers not very much. In particular, the manufacturer specifies the type of bearing with the original name HPLN (High Precision Low Noise). The speed of rotation of the “carlsons” can vary in the range from 700 rpm to 1300 rpm All fans are fitted with rubber strips that reduce vibration.

Deepcool Assassin II
Deepcool company in 2013 launched a sub-brand Gamer Storm. To it belongs the model and Assassin II. The kit includes everything you need. Contains fasteners for all modern CPU sockets and additional brackets for mounting two fans. No credibility only a nameless tube of thermal paste. It is small, it is enough for once. The interface is very viscous. Had to suffer with it spread over the surface of the heat distribution lid of the processor. Also included was a special adapter to combine the four fans.

At the time we tested the first version of “assassin”. Cooler left a very positive impression. The second version of the device somewhat modified. In particular, the engineers at Deepcool decided to abandon the symmetrical U-shaped design. The Assassin II plates have a different shape. In my opinion, this is done solely for the sake of design. Each section has 48 aluminum fins. They planted eight Nickel-plated teplorulon. Together with fan cooler height is 167 mm. decent Special exclusive technology in the creation of Assassin II is not seen. This is a classic two-tower cooler.

Included with the radiator are two fans of different sizes. From the outside is installed 9-blade 120mm impeller. The speed of its rotation can vary in the range of 300-1200 rpm. Just looking ahead, I will say that to get to work “wind turbines” at low revs so I couldn’t. In the first “assassin” also used a 120mm fan, however, to change its speed of rotation was not possible. The second “Carlson” is set between the towers. He can spin a little faster up to 1400 Rev/min.
Plastic frame with the motor and blades of the two fans placed in a rubber case. It is based on reliable hydrodynamic bearing. On the fan blades caused risk profile.
Deepcool Assassin II
To install Assassin II is used a universal backplate. It is also necessary for AMD and for Intel. The installation process is quite simple and does not take much time. This fastening system has long been used in tower coolers Deepcool. To secure the cooler, you need to remove the 140 mm fan.
Radiators have different thickness. Therefore, it must be installed so that side slots for RAM was as much space as possible. Otherwise, the Assassin II will cover all four DIMM slots. When properly installed, two. Suitable memory module height of 40 mm. In width “killer” is very compact for a device of this calibre. Problems with overlapping expansion slots the motherboard will not arise.

Noctua NH-D15S
Austrian manufacturer knows a lot about creating a two-tower coolers. At the time enthusiasts all over the world have conquered model NH-D14, and then came an improved revision under the name NH-D15. As you can see, model NH-D15S is derived from this supercooler. The seeming similarity of these two devices have a couple of noticeable differences.
The delivery of any Noctua cooler is a true role model. All items are carefully packaged in bags and distributed according to the type of the used platforms. As always, included is a l-shaped Phillips screwdriver and a large syringe of thermal paste NT-H1, which is enough for several times. The adapter L. N. A. reduces the fan speed from 1500 rpm to 1200 rpm.
Package contents Noctua NH-D15S
At first it may seem that the NH-D15S is a NH-D15 with one fan included. And it is at the core of the radiator are six Nickel-plated copper heat pipes. Each section consists of 45 aluminum fins. And yet the radiator NH-D15 has a fully symmetrical design. The NH-D15S deplorable and the partition offset so that when the same width of 150 mm, the cooler will not block the nearest slot. Therefore, the device is compatible with most motherboards form factor mATX. Otherwise the NH-D15S and NH-D15 are very similar to each other.

Included with the device is 140 mm fan NF-A15 PWM. Its maximum frequency can reach 1500 rpm With L. N. A. adapter the speed limit can be 1200 rpm. At the heart of “Carlson” is the hydrodynamic bearing SSO2 with a resource of approximately 150,000 hours.
Noctua NH-D15S
Installing any Noctua cooler is simple to a disgrace and takes only a few moments. To secure the mounting complaints, the power of a clip too. Through the use of just a single fan NH-D15S was the most shallow cooler. And yet two of the DIMM slot will be blocked. However, the plates have a special cutout on both sides. In the end, with this cooling system in the computer can be installed memory strip height up to 65 mm Slot PCI Express x16 motherboard does not overlap.

Testing
Test stand:
· Processor: Intel Core i7-5960X, 3.3 GHz (3.5 GHz), 140W.
· Motherboard: GIGABYTE GA-X99UD7 Wi-Fi.
· Memory: DDR4-2133 4x 8 GB.
· Video card: NVIDIA GeForce GTX 950.
· Storage: SSD, 240 GB.
· Operating system: Windows 10 x64.
Supercooler testing was conducted in several stages. I took the hottest to date, the Intel Core i7-5960X, the level of TDP which, according to official data, is 140 watts. The nominal clock frequency of the “stone” is 3.3 GHz but in Turbo Boost mode it is permanently increases to 3.5 GHz. I fixed the figure at around 3.5 GHz, so the testing was more relevant. All coolers were tested in three modes: with a minimum frequency of revolutions per minute of the fan/fans, average frequency and maximum speed of rotation of the impellers. The second stage — acceleration. CPU frequency was increased to 4 GHz. I had to increase the voltage from 1 V to 1.2 V. That’s such a bad chip I had. There are instances that can run at a voltage of 1.1-1.2 to 4.2 to 4.3 GHz. In any case, in this mode of operation Core i7-5960X will be a very severe test for any cooling system. When overclocking coolers fans worked in automatic mode. Hogged CPU software LinX 0.6.5 is the most resource intensive application for today. In 99% of cases at home, the system will not work in such conditions. For each mode was allotted 15 minutes. The room temperature at the time of testing was 25 degrees Celsius.
For each cooler was used the thermal paste supplied with the device.
The noise level was measured at a distance of one meter from the test stand. The system uses a PSU and a graphics card working in passive mode. The minimum level of noise in the room is 36 dB.
Let’s start with temperatures. For the beginning to the final table. All models manifested the same trend. Namely, there is a noticeable difference in cooling efficiency at low and medium frequencies of rotation of the fans. Apparently, in really gentle air blowers do not have enough efficiency to completely “pump” overall twin tower radiator. Especially strongly noticeable gap at the Cryorig R1 Ultimate and Deepcool Assassin II. In the first case, the difference between the hot cores was 13 degrees Celsius, while in the second 9 degree Celsius. At the same time, when average and maximum speeds of the impeller the temperature drop was less noticeable. The most passive was the Thermalright cooler. Changing the fan speed from 1000 rpm to 2500 rpm was allowed to take off with CPU only 4 degrees Celsius. As you well know, with markedly increased and noise.
As for the absolute comparison of the coolers, formally best result was shown by Thermalright Silver Arrow SB-E Extreme. However, the same result was shown and the Noctua NH-D15. Among the newcomers, test laboratory for the first time, was the best model from Cryorig. At maximum speed she was ahead of Deepcool Assassin II and Noctua NH-D15S 3.5 degrees Celsius, 3.4 degrees Celsius respectively. In General, all devices perfectly coped with cooling of the hot Core i7-5960X.
Supercolony buy for overclocking CPUs. To raise the frequency of eight-core “stone” with a TDP of 140 watts — not an easy task. Especially at high voltage. Overclocking to 4 GHz coped nearly all test takers. Cooler Deepcool during the stress test several times dropped the frequency to 3.7 GHz. It is in these moments were recorded maximum temperature. In the end, Assassin II took the last place. Model Noctua NH-D15S was just one degree better, but the processor in the allotted time was never off the clock with a preset frequency 4 GHz. This test period showed that among the tested models, the best margin of safety has Noctua NH-D15.
Eligible cooling efficiency is, of course, great. Only low temperatures are expected to align with a comfortable level of noise of a processor cooler. Here we take the model from Thermalright. Yes, this system was the most effective in the promotion 140mm impellers up to 2,500 rpm. However, the level of noise it can compete with small… vacuum cleaners. Call rate of 53.2 dB received at a distance of one meter from the stand for quality does not. Use a Silver Arrow SB-E Extreme in this mode is simply impossible. However, there is no point dwelling on the unit, extracted from trade.
Very noisy at speeds of from 1000 rpm was cooler Cryorig R1 Ultimate. In terms of cooling the most balanced look of the model from Deepcool and Noctua. Yes, when the maximum rotational speed of the fans, their work is noticeable, but it is not uncomfortable.
Now, having studied all aspects of the work of supercooler, we can safely say that the most balanced solution turned out to be Noctua. They efficiently cool the Central processor. Plus make it quieter than key competitors.
In conclusion
Yes, the device Noctua have once again demonstrated their high quality. Model NH-D15 won in today’s testing. The cooler the NH-D15S logically inferior to her, because in the device bundle is only one fan. The use of the second impeller with a high probability will allow to establish between these systems the equal sign. The design of the heatsink the NH-D15S perfect. Having such parameters, it is absolutely not in conflict with the other components.
At the same time, I really liked the device from Deepcool and Cryorig. Assassin II was the least effective among the considered today of supercooler. Nevertheless it has good noise characteristics. In addition, the cooler has the lowest price tag. This is a major plus of this model. Cooling R1 Ultimate almost equal to compete with the Noctua NH-D15. Yes, the cooler works noisier, but it is worth considerably less. With proper tuning you can always limit the fan speed. As shown by testing, the maximum speed of rotation does not always significantly affect the cooling efficiency.
Twin tower supercooler once again demonstrated his class. It’s a perfect solution for cooling the hottest CPUs. To achieve more efficient heat removal you need to use a water cooling system.
