CORSAIR iCUE LINK RX II RGB Fans: Everything You Need to Know

Fans in your PC build are more than just cooling components anymore. They now play other important roles beyond dissipating heat from hardware like the CPU and GPU. As new technologies are introduced into the DIY PC market, PC fans need to adapt to evolving PC systems, which means they need to level up in terms of performance, design aesthetics, and ease of installation.

As PC systems keep improving and getting faster, they naturally put more strain on their components, leading to more heat generation. This is why PC fans have to become more advanced, to levels we’ve never seen before. A perfect example is the CORSAIR iCUE LINK fans, introduced in 2024. If you have been in PC building for a long time, you know CORSAIR fans are known for their performance, quality, and new technology, like the CORSAIR iCUE LINK Technology.

Meet the newly improved iCUE LINK RX RGB fan family, the CORSAIR iCUE LINK RX II RGB PWM Fans. They come in different sizes, colors, and configurations, giving you lots of options to choose from to match your build.

Building on the same solid foundation as the previous iCUE LINK RX generation - focused on performance, technology, and ease of use, we’ve taken what worked best for many PC builders and applied that same winning blueprint to the RX II models. This time, though, noise reduction was the priority, making this iteration 4 dBA quieter while still delivering the same excellent cooling performance for your daily PC applications.

The iCUE LINK RX II PWM RGB fans have the same fan curve profile as their predecessor, enabling them to run quietly without compromising performance, thanks to CORSAIR AirGuide technology, which includes anti-vortex vanes that help focus airflow through your system for more efficient cooling. Since iCUE LINK RX II fan’s focus is reducing noise level, the PWM control needed to be tweaked more precisely to allow the fan to operate at a low RPM as low as 400 RPM all the way up to 1,200 RPM for 120mm spec and 300 RPM to 1,700 RPM for 140mm spec.

These two variants are technically the same in terms of specs, design, and build quality. The only difference is that one includes an iCUE LINK System Hub and the other doesn’t. What really makes these two RX II variants unique and interesting compared with any of CORSAIR’s fans in the past is the way they are constructed. Essentially, it is 3x RX120 II fans combined into a single housing, called Unified Frame, making installation a breeze, because you only need 4 screws to secure the fans, compared to 3x single 120mm fans, which would require 12 screws.

Not only does the Unified Frame design make the installation process much easier, but it also helps lower fan noise. The fan cables (power and data) are routed through the fan frame, reducing cable clutter behind the fan, minimizing turbulence for more streamlined airflow and lower noise.

Why choose this design? Cases that support 3x 120mm fans at the front or top, including support for 360mm AIO liquid CPU coolers, typically share similar fan-mount positions and screw spacing across different brands. Instead of securing each fan individually, which takes extra time, you can mount them all at once, making the assembly process quicker.

When choosing between the two RX360 models, the rule of thumb is: if you already have an iCUE LINK component/s in your PC, such as an iCUE LINK AIO Liquid CPU cooler or a custom liquid-cooled PC with Hydro X components that are iCUE LINK-compatible, the RX360 is the right play. But if you are starting a new build and want to take advantage of iCUE LINK Technology, the RX360 with Hub is the right choice because it includes the iCUE LINK System Hub, a key component of an iCUE LINK Ecosystem.
