Kyushu Fengshen Assassin 4S Radiator Review Air-cooled "Assassin Master" Style

Speaking of ASSASSIN, I believe players will definitely think of the master assassins in "Assassin's Creed". They are not only skilled, but also have the creed of "devoting themselves to the darkness and serving the light", which is consistent with the well-known domestic chassis/ The ASSASSIN series of flagship air-cooled radiators of the power supply/radiator brand DeepCool coincide with each other. Recently, the latest product in this series, ASSASSIN 4S, has been launched. "Assassin in Suit, Advanced" brings a new air-cooling experience to advanced players.

The appearance is full of details

The Assassin 4S radiator adopts a twin-tower structure with a single fan embedded design, and is covered with a cube-shaped fairing. , with a strong overall sense, and available in white and black colors to meet the installation needs of different colors. The size of the radiator is 116x147x164mm and the weight is 1380g. The material is very solid and there are certain requirements for the height of the chassis. However, according to experience, if the fan position at the rear of the chassis supports a 120mm fan, then this radiator can be installed.

The left, right and top of the radiator cover adopt a three-section design, and the middle part is a metal decorative mesh. Since this radiator uses a built-in fan and a balanced symmetrical tower, how to determine the front and rear and the direction of airflow?

The answer is very simple, just look at the shape of the heat dissipation fins. The fins on the front are made into a concave and convex square matrix shape.

The fins on the back have a very neat wavy pattern...or do they look like instant noodles? We can also see that the fairing forms a very typical through-type air duct, gathering the turbulent flow on both sides of the fins to further improve heat dissipation efficiency.

#The upper right corner of the top is the fan speed switch. You can choose between full speed mode and quiet mode. If you want quietness or performance, just dial it.

#######################################################################################In the lower right corner of the top is the brand logo of Kyushu Fengshen. When powered on, it can emit blue-green light, and can change the light and dark effects according to the mode of the fan speed switch. ###############The steel mesh on the top is magnetically fixed to the radiator. After opening, you can see the cooling fan embedded between the twin tower fins. The top of the fan Arrows represent the direction of airflow. ################The fan adopts a quick-release design, and you can pull it out by pinching the spring leaf fixing buckles on both sides of the fan. The fan is overall gray, and the 140mm size looks very large and very weighty. ###############The fan blades are made of high-strength materials. The seven blades have large areas and smooth twist angles, and the dynamic balance is outstanding. ###############The fan uses a three-phase six-pole motor and supports PWM speed regulation. The operating voltage and current are only 12V 0.2A. It is also equipped with FDB bearings, which means that it can not only bring With higher air volume, noise control will also be excellent. ###############The radiator base runs through seven 6mm bidirectional constant heat balance heat pipes, and the white spray paint is integrated with the radiator. Of course, remember to remove the protective sticker on the surface of the base before installation. ###############The base is made of pure copper, and the contact surface adopts nickel plating process and finely processed micro-convex texture. It is matched with a frame-type buckle to increase the heating area and improve heat exchange efficiency. . ############

Various accessories inside the box, including DM9 thermal grease, L-shaped long-stem double-head simple screwdriver and installation buckle. The Assassin 4 cooler's clip supports Intel's LGA1700/1200/115x socket, as well as AMD's AM5/4 socket, covering existing mainstream platforms.

Installation practice

After installing the CPU on the motherboard, you can install the Assassin 4S radiator buckle, which must have "CPU" on it. " arrow points to the CPU, so as to ensure the correct screw spacing on the radiator base.

#Install the memory, pay attention to the direction of the gold finger of the memory, and do not install it backwards. It is worth mentioning that the height of the Assassin 4S radiator heat pipe is compatible with various types of memory with heat dissipation vests, and will not interfere during installation.

The Kyushu Fengshen CH160 chassis we used for this installation made its debut at CES2024 this year. It has a very high appearance and uses miniITX specifications, but the body is 336x200x283.5mm. The shape can be installed with a 172mm height air-cooling radiator, and a 305mm length three-slot graphics card can be directly inserted. Combined with the through-type air duct, it can bring excellent heat dissipation effect. The chassis is made of ABS SPCC steel dual materials. The left side adopts a mainstream glass side-transparent design. The top, bottom and front are hollowed out with square grids and equipped with dust-proof nets. The top is equipped with a handle for easy carrying for short distances. In terms of color matching, this chassis is also available in black and white, especially the white color that matches perfectly with the Kyushu Fengshen Assassin 4 radiator we tested.

Jiuzhou Fengshen CH160 white chassis supports two specifications of power supplies: ATX and SFX. Since we chose the NVIDIA RTX 4070 SUPER public version graphics card for this installation, in order to avoid interference in the installation position To ensure the heat dissipation effect, we chose the SFX power supply with compact size and higher power density, and installed the power extension cord.

Install the miniITX motherboard into the chassis. It should be noted that the Assassin 4 radiator is larger and requires the removal of the two overhead fan mounting strips on the top of the case.

Apply silicone grease to the surface of the CPU and spread it evenly with a plastic spatula to further improve thermal conductivity.

First take out the fan of the radiator, place the radiator on the buckle, and then use a long screwdriver to tighten the fixing screws on the base.

Install the fan back into the radiator and pay attention to the air flow direction, then plug the fan plug into the socket of the radiator speed controller, and then connect the 4Pin of the radiator Plug it into the CPU FAN socket on the motherboard.

In order to install the NVIDIA RTX 4070 SUPER public version graphics card, you need to remove the first and second slot baffles of the chassis and connect the 16Pin 12VHPWR power supply.

The last thing is cable management. Since miniITX chassis space is generally small, it still takes some effort and thought to route various wires as nicely as possible, and Ah Sahin 4 This radiator has a very full visual effect in the chassis, and together with the graphics card and power supply, it has a modular feel.

After powering on, set the memory light to the same light blue-green color as the radiator and power switch. Isn’t the visual effect very eye-catching?

Roasting machine test, powerful performance

Assassin 4S In addition to its good looks, this radiator has 7 heat pipes and a 140mm fan, which also brings a cooling power consumption of up to 250W. Since the installed B760 ITX motherboard only provides a maximum power supply capacity of 110W, we paired it with a Core i5- The 12400 processor is used as a reference for everyone. The test project is the Stress FPU in the AIDA64 system stability test, which is commonly known as "single baking". At this time, CPU-Z shows that the full core turbo frequency has reached about 4GHz, and AIDA64 shows that the maximum power consumption is about 85W.

Set the fan of the Assassin 4S to full speed, which only spins around 1200RPM at full load. After 20 minutes of baking, the temperature of the whole process is basically maintained at 66~67 ℃. It can be seen that the Core i5-12400 with 65W TDP will cook small dishes or even waste everything. If the motherboard power supply allows, it is expected that the single baking temperature of the Core i7-14700 will be 92~ Around 94°C.

When testing the oven, we also tested the internal temperature of the chassis. The idle state was 26.8 ℃, and after 20 minutes of oven testing, it rose to 29.1 ℃. , the temperature rise is less than 3 ℃, which shows that the heat dissipation effect of Kyushu Fan Assassin 4S radiator paired with CH160 chassis is very powerful.

Finally

As the new flagship product of Kyushu Fengshen’s twin-tower air-cooling, Assassin 4S attracted a lot of attention after it was exhibited at CES 2023 last year. Players are paying attention to this radiator. Not only does it have good looks, but its heat dissipation performance of up to 250W ranks among the high-end air-cooled radiators. It even faces some entry-level water cooling without fear. It is worthy of the name of "Assassin". It is also compatible with all platform processors, making it an ideal choice for users who pursue performance and stability. Currently, this high-performance radiator has been launched on the e-commerce platform and comes with a six-year original factory warranty. Players who need to install or upgrade their computer can consider purchasing it.
