The gaming brand Republic of Gamers from ASUS expands its coverage of various areas related to computer games every year. At recent Computex and CES, we have seen not only new gaming peripherals, but also cooling systems, computer cases and even chairs under the ROG brand. And although in the assortment of cooling we came across all the same maintenance-free CBOs manufactured under the license of Asetek that have set the teeth on edge over the past five years, we must admit that ASUS managed to add its own zest to them. This review will focus on the new product, which is called ROG Ryujin 360 and is the top CBO in the company’s lineup. Its notable feature is the stock Noctua NF-F12 industrialPPC 2000 PWM fans. Everyone has long been waiting for Noctua to start releasing its CBOs, but the Austrian company went the other way. And now we see the first ever example of cooperation between Noctua and ASUS in the field of cooling. In addition, the Ryujin 360 boasts another fan built on top of the pump that cools the area around the socket. And the last “chip” of this system is a 1.7″ screen located on the front side of the water block, where you can display not only funny pictures, but also useful information about the state of the system. And all this is complemented by a strip of RGB LEDs that runs diagonally above the screen, where without it … In general, let’s look at all the features of the ASUS ROG Ryujin 360 in order.
Packing and scope of delivery
Packed Ryujin 360 in a box typical of Asetek CBO, made in black and red colors of the ROG brand. On the front side there is an image of the product, on the back – its advantages are listed in the form of pictures with text and detailed technical characteristics are given.
Inside, all parts are packed in plastic bags and a mold made of pressed cardboard.
In addition to the heatsink and water block, the ASUS ROG Ryujin 360 comes with:
- installation instructions;
- three 120mm Noctua NF-F12 industrialPPC 2000 PWM fans;
- magnetic plastic pad on the water block;
- plastic reinforcement frame for Intel LGA 115x and 1366 sockets;
- four racks for Intel LGA 2011 sockets and its analogues;
- four racks for Intel LGA 115x and 1366 sockets;
- mounting metal frame for AMD AM3 and AM4 sockets;
- four racks for AMD AM3 and AM4 sockets
- four knurled nuts with a hole for a Phillips screwdriver;
- 24 short screws for mounting the radiator;
- 12 long screws for mounting fans;
- 24 metal washers.
Appearance
The external design of the Ryujin 360 radiator is fully consistent with the Asetek three-section design reference, but the water block has a more original appearance. The pump is connected to the radiator by 380 mm rubber hoses wrapped in nylon braid. The outer diameter of the hoses is 11 mm, and the inner diameter is about 7 mm.
The radiator is made of aluminum and completely painted in black. Its total length is 394 mm, width 121 mm. The side slats have three sets of mounting holes for 120mm fans, arranged without clearance. Radiator fins are band-type, stacked at 20 FPI (fins per inch). Between the fins are 14 channels through which the refrigerant is pumped. The two extreme bands of plates on the sides are narrower than the rest. The total heat dissipation area is approximately 8400 cm². The weight of the equipped system without fans is 1 kg.
The tubes are fixedly connected to the radiator fittings by pressing, plastic clips. The thickness of the manifold on the hose side is 19 mm.
The collector on the opposite side has a thickness of 14 mm. The serial number of the product is pasted here.
The thickness of the radiator complies with the standard 27 mm. On the sides there are four rivets on each side.
The water block on top is made of plastic and looks specific. By and large, it consists of three separate parts. On top is an electronic unit with a display and a line of RGB LEDs. The two round holes on it with metal inside are magnetic mounts for the square lid. Under the board there is an air intake hole, then there is a fan for blowing around the socket space, which is placed directly on top of the pump. And around the pump itself there is a plastic “skirt” that directs the air flow in the right direction.
The hoses are connected to the water block with the help of angle fittings that easily turn sideways to decent angles. Unfortunately, after putting on the square plate, the actual allowable angle of rotation of the fittings becomes extremely limited. The pump installed inside has a PWM speed control in the range from 800 to 2800 rpm. At the same time, the levels of emitted noise range from 37 to 39 dB (A). It will not work to make the noise less, since the fan installed on top of the pump has a fixed rotation speed of 4800 rpm. Interestingly, it works quite quietly, at least quieter than the pump at maximum speed. The performance of a small propeller is 33 m³ / h at a static pressure of 3.94 mm of water column. In general, this whole system is silent at low speed, but emits a characteristic buzz at maximum.
There is nothing remarkable on the left and right sides of the water block. All non-removable external cables are attached to it from the side of the hoses. The only thing that caught my attention here was the cable under the electronic board, which is pressed against it with adhesive tape. I wonder when it peels off completely, will the cable get into a small fan?
There is also nothing in the front projection on the water block. It is noteworthy that its height is 64 mm. And if there were no electronic board with a screen here, the unit would be almost half as low, and its fan would receive direct air access. Perhaps ASUS will someday think of such a modification.
The base is round and copper, with a diameter of 54 mm. The sole of the cooler is attached to the pump with eight hexagonal screws screwed in around the perimeter. By default, a thin layer of thermal paste is applied here. The frame with fastening paws is spring-loaded, easily removed by pressing and turning counterclockwise. Installation takes place in the reverse order. “Out of the box” there is a frame suitable for installing a cooler on Intel LGA 115x / 1366 / 2011 sockets.
After removing the thermal paste, we can visually verify that the copper sole is made quite even and has a transverse linear polishing.
A set of wires is soldered to the water block. Among them there is a PowerSATA power connector, 300 mm long, a four-pin power cable for the pump (also 300 mm), an output for powering three four-pin fans (280 mm long, with two tails of 50 mm each) and a USB 2.0 cable needed to control the display and light effects, 930 mm long. The pump and fan speeds are controlled synchronously by a PWM signal from the CPU FAN connector.
A plastic square pad is put on the water block after installation and is held on by two magnets. It is designed to give the system a more aesthetic appearance and does not perform any other functions. On top of it there is a transparent plastic window and an aluminum insert with an inscription. The side panels have ventilation holes on all sides.
ASUS ROG Ryujin 360 uses three proprietary Noctua NF-F12 industrialPPC 2000 PWM propellers as fans, which we already reviewed once in one of the reviews. Their only difference from the production models is that the rubber pads on the corners have changed their color from brown to black. The rest is all the same. Proprietary hydrodynamic bearing Noctua SSO2 with 150,000 hours MTBF, an impeller with seven shallow blades, under which there is a set of guide deflectors to concentrate the air flow. The speed range is from 450 to 2000 rpm, noise levels are from 35 to 60 dB (A), respectively. The fan remains silent up to approximately 900 rpm and 39 dB(A), but when installed on a heatsink, these parameters drop to 700 rpm and 40 dB(A). Relatively comfortable for hearing is the speed threshold of 1300 rpm on the radiator. And spinning the impeller faster and does not make much sense, as practical testing shows, since the noise level increases greatly with a minimal difference in temperatures. The length of the four-prong rubber-sheathed cord is 400 mm.
This is how the fans on the radiator look like:
Assembled with fans, the total thickness of the system is 52 mm, provided that the screw heads are recessed into the rubber mounts.
Let’s move on to installing the CBO and testing its effectiveness.
