Graduation level air cooling and heat dissipation, overclocking three RZ820 Terra Giant Wind exposure sheet, with 14700K overclocking measurement

Written on the front

Friends who pay attention to DIY should have found that in recent years, water-cooled products have been booming, and there are bright product releases in low, medium and high-end, which make players' eyes shine. However, water cooling has always had the drawbacks of noisy water pumps and serious decline in heat dissipation effect after a few years, as a quieter, more stable and safer air cooling, in addition to the 100-yuan market volume has not changed, in the flagship field, there has not been an impressive product for a long time.

However, the RZ820 that has just been released by Overclocking III is very eye-catching to me, while ensuring that the size has excellent compatibility, it gives the performance of the first echelon at this stage, claiming that it can suppress the top power consumption of 290W. So what is the performance of this giant twin towers that are positioned as graduation level air cooling, let's take a look at it together.

Unpack and dry the goods

Since the new design style of the overclocking three was launched last year, their heat dissipation products, especially the new air cooling, have suddenly come up in appearance. The outer packaging has also changed from the original bells and whistles to a low-key but exquisite design.

The first thing you see when you open the outer package is a detailed accessory package, and the three air-cooled buckles for overclocking have been classified for us according to the general and INTEL/AMD platforms, which is full of ceremony. It is worth mentioning that the RZ820 buckle will be used with the new air-cooled and water-cooled products, which greatly facilitates the disassembly and assembly cost of the user's subsequent upgrade/replacement, and is well received.

The weight of the flagship air-cooled is quite amazing, so all the buckles of the RZ820 are made of high-toughness manganese steel to ensure that they will not be deformed after long-term use. Take out the radiator body and you can find that it is a square shape, with an all-black design, which is quite tough.

The three-dimensional size of the heatsink is 161*150*165mm, and the height of 165mm can be easily stuffed into most MATX cases on the market, and even some ITX cases can experience the effect of installing the motherboard on heat dissipation. The magnetic top cover is made of aviation-grade aluminum alloy, CNC precision turning and milling and anodic sandblasting process, the surface is delicate and comfortable, and it is not easy to get fingerprints.

Then let's look at the core configuration of the RZ820, and turn the heatsink over to see these 8 exaggerated oversized heat pipes, 4 of which are 8mm diameter and the other 4 are 6mm diameter. The bottom of the heat pipe adopts a new polymerization process, the micro-convex and carved pure copper base can ensure that every heat pipe touches the CPU, and the EX90 silicone grease is pre-coated from the factory for easy installation.

Take off the magnetic top cover to see the internal structure of the RZ820, and the 8 heat pipes are flat after entering the twin towers, which can effectively reduce the wind resistance. It is equipped with 120+140mm dual fans at the front and rear as standard, and the 140mm fan is a tool-free installation hidden under the top cover, which is a very clever design.

The giant twin tower structure can be seen from the back, and the fins are fully reflowed, ensuring that each fin is evenly spaced to reduce heat build-up. The fins adopt the folding FIN + buckle FIN process, which can reduce the turbulence of the air duct. Trigonal geometry family wavy fin shape to reduce running shape.

Finally, let's take a look at these two high-performance silent fans. The 120mm front fan adopts a slide rail structure, which can flexibly adjust the height, and supports a maximum of 62mm vest strips, which is better compatible with memory. The measured Acer Predator Ice Blade only uses the middle gear, and there is still a lot of reserved space.

The front fan is 25mm thick and has an aviation aluminum frame, which can ensure the stability of the air duct at high speed. There is an overclocking three LOGO in the middle of the fan, and FDB dynamic hydraulic bearings are used to effectively improve the service life and reduce the running shape. The fan can provide a speed of 500~2200RPM, a maximum air volume of 147.3m³/h and a maximum air pressure of 3.2mmH20.

Then let's take a look at the hands-on effect. I have to say that the top cover of this CNC + anodic sandblasting process is really exquisite. There is a CPS logo on the top, and a triangular ARGB lamp bead with high-gloss nickel plating process at the bottom, which supports ARGB divine light synchronization, which has a unique charm.
