In the PC cooler market, there are two major factions: air-cooled and water-cooled. Although the all-in-one water cooling radiator is now favored by more and more people, and the price is getting lower and lower, there is still a large market for air-cooled radiators. Some manufacturers have also launched flagship air-cooled coolers especially for the high-end market, such as the newly launched Terra Gaugon RZ820 is one of them. This product has 8 heat pipes, and with the blessing of the reflow soldering process, it is claimed to be able to achieve 290W heat dissipation power. It is important to know that this heat dissipation power consumption is close to the limit of current air-cooled radiators. So how does it perform in all aspects? Let's find out.

The shape is square and domineering
Many mainstream air-cooled radiators on the market have a feature: most of the fans they are equipped with are fixed to the heat dissipation fins through metal wires, and due to their simple structure, most of them have the same appearance, lack of aesthetics, not to mention a sense of design.
Compared with ordinary air-cooled radiators on the market, the overclocked Tritera Gale RZ820 has a more holistic appearance, and looks more refined, square, and tough, with rounded corners. It is worth mentioning that the RZ820 has a shell and a magnetic top cover on the outside of the radiator body, which has several benefits: first, it can make the overall appearance more regular and good-looking; Secondly, it also helps to avoid turbulence in the fan, which in turn improves heat dissipation. At the same time, the addition of an enclosure can also play a role in protecting the radiator from damage to the heat sink fins due to external collisions.
▲RZ820 incorporates the family's "triangular geometry" elements, such as the triangular design of one side of the heat dissipation fin.
In addition, the aviation aluminum magnetic top cover it uses is also a highlight. This magnetic design allows the user to easily remove and install the top cover, making it easier to clean and maintain the radiator. The top cover adopts CNC and anodic sandblasting technology, so that the whole has a better texture.
▲RZ820 adopts a magnetic top cover, and the side of the top cover is equipped with a handle.
▲ Under the top cover, the RZ820's fan and lighting effect part are hidden
The heatsink also incorporates a family of "triangular geometry" elements, with a light-emitting plate in the corner of the top cover, ARGB support, and synchronization with mainstream motherboard lighting systems. Next to it is its LED illuminated logo, which does not support RGB lighting effects.
▲The lighting effect part of the RZ820 is evenly displayed on the outside through the light emitting panel.
配140mm+120mm双风扇
The RZ820's internals are similar to the Assasin 4 we've experienced before, with a twin-tower structure and two cooling fans inside. Between the twin towers is a 140mm fan, while the outer fan is 120mm. Not only that, but I noticed that the RZ820's twin towers are not covered with shells on both sides, which is designed to ensure heat exchange on the outside of the towers, so that the heat can be dissipated more quickly. Another important reason is that the RZ820 has reserved a place to install the third fan, and it is equipped with a fan wire in the accessory, so users only need to buy a fan to mount it to the tower. In order to prevent conflicts with the motherboard's thermal armor, it is recommended that the third fan be mounted with a size of 120mm.
Open the metal top cover, the fan in the middle of the radiator adopts a special-shaped design with a circle at the top and bottom, and at the same time, there are two handle designs above the fan that are easy to take out, and the user only needs to pinch the two ends with his hands and lift them up, so that the fan can be easily removed for cleaning.
The RZ820's fan between the twin towers comes from the OC three, the exact model is unknown, and the middle and external fans are equipped with Fluid Dynamic Bearings, which are commonly known as hydraulic bearings. Thanks to the use of oil instead of conventional balls, this bearing technology does not operate with the sound of metal-to-metal friction, resulting in no wear problems, longer service life and lower noise. The fan speed on the outside of the radiator is 500~2200RPM, the air volume is 147.3m2/h, the air pressure is 3.2mmH2O, and the noise is 32dB (A); The fan speed in the middle is 400RPM~1500RPM, the air volume is 122.16m2/h, the air pressure is 3.2mmH2O, and the noise is 27.1dB(A). As you can see, the fan on the outside rotates at a higher speed and has a higher airflow, because the fan on the outside needs higher performance to increase the inlet airflow, but at the cost of higher noise.
▲RZ820 Accessory Package
It adopts 8 heat pipes and reflow soldering process
The RZ820 is positioned as an ultra-flagship air-cooled radiator, and to reflect its "ultra-flagship", it comes with 8 heat pipes. You must know that there are not many air-cooled heat sinks with 8 heat pipes at present, most of them are 7 heat pipes. Its heat pipes are blackened to prevent oxidation. At the same time, the black coating also increases heat radiation and enhances heat conductivity. The heatsink is equipped with 4 Φ8mm and 4 Φ6mm heat pipes, and I noticed that these 8 heat pipes are arranged in a somewhat peculiar way, with 1 6mm heat pipe on each side, then 2 8mm heat pipes on each side, and finally 2 6mm heat pipes in the middle. Why is it arranged in this way? The purpose is to make the heat conduction more uniform, because the heat generation near the edge is relatively low, and the heat in the middle area is relatively concentrated, so 4 8mm heat pipes and 2 6mm heat pipes are arranged in the middle position.
▲ The 8 heat pipes used in the RZ820 can be seen that it uses a combination of 4 8mm and 4 6mm.
The RZ820 adopts a matrix fin group, which can effectively increase the heat dissipation area and improve the heat dissipation effect. In order to make the fins more tightly connected to each other, the fastening and folding Fin process is used between the fins to ensure that the gap between the fins is minimized. However, due to the traditional fin threading process, the fit between the heat pipe and the fin cannot reach 100%, so it will inevitably leave some small gaps, which will affect the heat dissipation efficiency. To solve this problem, the RZ820 employs a better reflow soldering process. Compared with the ordinary fin process, reflow soldering can completely fill the gap between the heat pipe and the fin, thus greatly improving the thermal conductivity efficiency. The welding process ensures that the contact area between the heat pipe and the fins is maximized, and the heat can be transferred more quickly and efficiently, so that the efficiency of the entire heat dissipation system can be significantly improved.
In addition, the RZ820 also features a large copper bottom design that can completely cover the surface of the flagship desktop processor. The surface of the copper base is also nickel-plated, which improves its corrosion resistance and heat dissipation performance. The same reflow soldering process is used between the copper base and the heat pipe to ensure a tight fit between them, thus further improving the efficiency of heat transfer.
The copper base of the RZ820 is pre-coated with thermal grease, and the cover can be removed when using. In addition, OC III equips the RZ820 with EX90 high thermal conductivity grease, which allows the heatsink to efficiently release heat and improve heat dissipation. This grease has a capacity of 1g, which is enough for 3~5 applications, and it is the same grease used in the DE360 liquid cooler and Zhen RZ620 BK air-cooled cooler that we have previously reviewed. According to official data, the thermal conductivity of EX90 silicone grease is as high as 14.8W/m.K, the thermal impedance coefficient is 0.03°C/W, and the operating temperature range is -50°C~250°C. It is able to maintain good thermal conductivity in extreme temperatures, making it suitable for high-performance processors.

RZ820 can adapt to Intel LGA 115X/1200/1700/18XX/2011 and AMD AM4/AM5 mainstream platforms, it can be seen that in addition to adapting to mainstream desktop platforms, it can even apply LGA 18XX interface processors. It is also relatively simple to install, for example, the Intel platform only needs to replace the backplate and fix it with a special fastener. The AMD platform is even simpler, requiring only the replacement of the columns, not the backplane. In addition, the hardware that holds the buckle is marked with a directional pointing arrow, so simply follow the direction the arrow points to install it.
When installing such large heatsinks, it is recommended to first install the memory on the motherboard, with the side of the heatsink with the external fan facing the memory side and the fin side facing the I/O port side. Because most chassis are designed with forward and rear air ducts, this installation can adapt to mainstream chassis air ducts. The size of the heatsink is 161mm (L)×150mm (W)×165mm (H), plus the external fan adopts a slide rail structure, which can be moved up and down, and the memory avoidance design is also added to the tower, so that users can easily disassemble and assemble the memory without disassembling the heatsink. At the same time, the height of the radiator is 165mm, and it will not conflict with the side panel of the case, and the height limit of the radiator of the general M-ATX and ATX cases is mostly more than 170mm.
▲RZ820 is just compatible with the 48mm height of the HOF EXTREME D5-7200 memory, there is no extra gap, if it is higher than this height, you need to adjust the fan height.
From our experience, the cooler's fan is fully compatible with our ROG Z790 DARK HERO motherboard without any adjustments. The motherboard is equipped with HOF EXTREME D5-7200 memory, which has a height of 48mm, so you don't have to adjust the height of the external fan of the heatsink after installation. There is a gap of about 10mm between the lighting module on the motherboard near the I/O port side and the radiator tower. At the same time, it does not affect the installation of M.2 SSDs close to the PCIe slot, and there is also an 8mm pitch after the graphics card is installed. In terms of hardware compatibility, RZ820 is compatible with mainstream motherboards and memory.
Meet the heat dissipation requirements of high-end processors under high loads
The RZ820 officially has a nominal heat dissipation power consumption of 290W, so how is the performance? Next, we will test it. We limited the processor power consumption to 290W in the motherboard BIOS and lifted the temperature limit of the processor in the motherboard, and then single-baked the PPU with the help of the AIDA64 System Stability Test and ran it continuously in a room temperature 21°C evaluation room for more than 30 minutes.
According to the test results, the processor has a maximum package temperature of more than 106°C (performance cores) when processing the Core i7-14700K at a maximum of 5.4GHz (not all performance cores). At this point, its power consumption is 289.8W. Judging from the test, it would be a bit far-fetched to use the RZ820 to fully unleash the performance of the Core i7-14700K, but after removing the temperature limit and limiting power consumption, the performance of the RZ820 can also meet the cooling needs of high-end processors under high loads.
In fact, the Core i7-14700K often consumes more than 300W of power when the temperature wall limit is removed in the full-load test, which is a big challenge for many flagship 360mm liquid coolers if you want to get the full performance of the processor. When the system detects that the temperature is too high, it adjusts the voltage or frequency to reduce the power consumption of the processor. In addition, if you're using a high-end processor like the AMD Ryzen 9 7950X, there is usually not much difference between the nominal TDP and the actual power consumption used due to the more advanced manufacturing process of the Ryzen processor. The maximum power consumption of AMD Zen architecture consumer processors usually does not exceed 200W, and it will be easier to use with the RZ820.
▲When the Core i7-14700K is released from the temperature limit and the limit of 290W power consumption, the maximum temperature of the RZ820 will reach 106°C in the limit state, which usually does not have such a high load for daily use, and it is completely sufficient if the desktop consumer-grade Ryzen processor is suppressed.
At the same time, the fan will also be kept running at full speed during the full load test. At the highest speed, we measured the noise value of 46.5dB(A) at a distance of about 50cm from the radiator by a decibel meter out of about 39dB(A), which is relatively low. Since we were testing on an open platform, if we were installing it inside a chassis and at a longer distance, we would hear less noise.
Write at the end
Compared with ordinary air cooling, the overclocked Triterra Gale RZ820 is not only stronger than the 8 heat pipes it uses, but also better in terms of appearance and internal design. For example, its appearance is more regular, especially the addition of a reflow soldering design, so that the performance of the heat sink can reach up to 290W, but this is the performance in the limit state. In day-to-day use, the RZ820 is able to meet the cooling needs of 14th Gen Core with K processors in high-load scenarios, such as graphics rendering and gaming, while suppressing the lower power AMD Ryzen processors with ease. Of course, the price of 999 yuan is not low, and it is worth a try for fans of air-cooled radiators.
