On Douyin, I often brush up on some installation bloggers, most of whom will install a set of water cooling radiators for customers, so many people are planted. But in fact, air cooling is still the mainstream choice, one is the cost is relatively low, and the other is that the air cooling radiator is enough to suppress the heat of the mid-to-high-end CPU, such as i3 and i5, there is no need for water cooling, please ignore it. A few years ago, I upgraded my home computer from the 12th generation i5 to the 14th generation i5, and by the way, I changed a set of radiators and chose the overclocking Sanzhen RZ620. This is a set of flagship-level air-cooled radiators, 6 heat pipes, a double-tower structure design, and two performance fans, which is enough to pile up materials.
The packaging continues the classic gray style of the OC III, with a render of the heatsink and the model number printed on the front, and two triangular decorative textures embellishment, simple and recognizable.
The package is packed with a radiator body, two fans, fixing fasteners/screw packs, installation instructions, and an overclocked triple EX90 thermal grease (1g pack).
The RZ620 heatsink has an all-black design, which is not inconsistent with most black-style cases. Its materials and workmanship are also very solid, it feels very weighty in the hand, and the whole is also very tight, unlike the baggy feeling of cheap radiators. The size of the three measurements after matching the fan is 130*142.5*157.5 mm, which can be compatible with mainstream cases.
The shape follows the "triangular geometric aesthetics" and incorporates a lot of triangular elements. The top of the heat dissipation fin is equipped with an aluminum alloy top cover, the surface is anodized, the dark gray metal texture is very delicate, and there is a three-dimensional embossed overclocking three new version of the LOGO in the upper left corner. The bottom of the top cover is also specially made of a triangular oblique shape, not only has a concave and convex texture, but also has an orange decorative line on the side, and the contrast stitching looks very refreshing.
The heat dissipation fins on the side are very dense, the material is also very thick, and the buckle Fin + Fin process is used between the single pieces, which ensures that the structure is stable and beautiful, and at the same time, it can effectively gather the air flow and make the air duct unobstructed. A closer look reveals that the side surface of the fins is shaped with a triangular wavy shape, and the aeroacoustic principle is introduced, which can reduce the noise of the wind shear and reduce the noise while ensuring the heat dissipation performance.
The lower part of the fins is connected to the pure copper heat dissipation base through six heat dissipation copper tubes, which are independently developed by OC 3 and run through the two sets of heat dissipation fins, whether they are installed horizontally or vertically, to ensure that the heat dissipation effect is not compromised. The surface of the pure copper base has a laser-engraved micro-convex CD pattern, and the area is relatively large, which can fully cover the Intel Core 12th generation and above CPU.
The two standard fans are the OC F5R120 performance fan, which belongs to the standard 120*120*25 specification. The fan blade is designed with 9 thickened pieces, with a tilt angle of 39 degrees, optimized according to the principle of aeroacoustics, and corrected by M/g three-axis dynamic balance, which can maintain stable operation, low noise and large air volume.
The middle of the fan adopts high-quality FDB dynamic hydraulic bearing, which has low noise and long life, and the theoretical working life can reach 60,000 hours, which can provide long-term and strong power for the fan.
Then install the cooler into the chassis, and the RZ620 cooler is compatible with the Intel platform LGA115X/1200/1700 specifications and the AMD platform AM4 and AM5 specifications, which can be used by basically the current mainstream CPU platforms.
After installing the backplate and buckles, evenly apply push grease on the back of the CPU, and then press the main body of the cooler up to make the bottom of the copper seat firmly fit the back of the CPU, and then tighten the heatsink and fastener tightly.
Next, attach the fan to the radiator and fix it with the included fan buckle.
The last step is to connect the cables of the fans, the two fans use 4PinPWM male and female connectors in series, the cables can be connected in series, and then plugged into the socket of the motherboard. Of course, if there are other fans in the case, they can also be connected in series.
This is the final installation effect, not bad, plus two aluminum alloy top covers, the aesthetics have indeed improved a lot, and the overall look is more concise and capable. If you can follow up with a fully wrapped top cover, it would be even more perfect to wrap the sides of the two fans as well.
Next, let's test its heat dissipation ability, after normal boot, Master Lu detected that the CPU temperature is 25 degrees, and the motherboard temperature is 28 degrees.
After 20 minutes, the CPU temperature is 43 degrees Celsius and the motherboard temperature is 30 degrees Celsius. It can be seen that when the CPU is fully loaded, the RZ620 air cooler can still control the temperature in an ideal state, and there is no problem of high temperature frequency reduction at all.
It is worth mentioning that the fan of this cooler also supports three speed adjustments, which are divided into quiet mode, PWM mode and OC mode, the default is PWM mode, and the speed can be automatically controlled by the motherboard according to the temperature of the CPU. If you have personal needs, you can adjust to the other two modes via the toggle switch on the fan controller.
In the case of normal office use of the computer and low hardware load, the noise near the test chassis is 51 decibels, and the ambient noise is 33.4 decibels, which shows that the noise control is quite good, and the sound is basically inaudible when the chassis is placed under the desk.
It has taken more than a month since it was installed after the year, and the overall performance of this radiator is very good. Not only the appearance design is simple and stylish, the materials and workmanship are also very solid, whether it is daily use or specially for baking test, the temperature suppression effect of the CPU is excellent, and the use of aeroacoustic principles balances the heat dissipation capacity and noise performance, providing a reliable guarantee for the "cool" operation of the computer.
