This article covers CORSAIR iCUE LX120RGBファン ホワイト.

Overview

CORSAIR's iCUE LINK LX120 RGB Expansion Kit brings a modern 120mm PWM fan with a dual light loop design to the iCUE LINK ecosystem. Each fan houses 18 individually addressable RGB LEDs arranged in two concentric loops, creating smooth, diffused lighting effects that look fantastic through tinted glass or mesh panels. This single-pack variant (model CO-9051029-WW) ships in white, with a black version also available. It spins up to 2,400 RPM, pushing 69.9 CFM of airflow at 5.22 mmH₂O static pressure — enough to serve as a capable radiator fan for AIO liquid coolers. The fan uses CORSAIR's Magnetic Dome bearing to reduce friction noise and extend lifespan. At its core, the LX120 is designed to work with the iCUE LINK system, which replaces the usual tangle of individual PWM and RGB cables with a single daisy-chainable link. This reduces cable clutter dramatically and makes fan installation much cleaner, especially in builds with 6 or more fans.

Compatibility Guide

You will need a separate iCUE LINK System Hub (not included) to power and control these fans via the LINK ecosystem. The hub connects to a USB 2.0 internal header and SATA power, managing up to 14 LINK devices. Physically, the fan fits standard 120mm mounting holes, so it works with virtually any case that supports 120mm fans — ATX, MicroATX, or Mini-ITX. The fan depth is the standard 25mm, so clearance for radiator combos is typical for the form factor. You can technically connect the fan directly to a motherboard PWM header via its 4-pin connector, but doing so disables all RGB control. For full functionality — daisy-chaining, RGB customization, and firmware updates — the iCUE LINK System Hub is mandatory.

Product Info

Released in early 2024, the iCUE LINK LX120 RGB sits in the mid-to-high tier of CORSAIR's fan lineup. It offers better build quality and lighting than the older QL and SP series, standing alongside the AF ELITE series in performance. The single-pack retails for around ¥4,700 on Japan, while a three-pack bundle that includes the System Hub is also available at a higher price point. CORSAIR backs this fan with a 2-year warranty. Be sure to verify the authorized distributor (ASK) sticker on the package if buying from third-party sellers.

Best Use Cases

Building a full iCUE LINK ecosystem: If you already own a LINK-compatible pump, AIO, or other fans, adding the LX120 RGB maintains a cohesive, low-cable environment with unified RGB control via iCUE software. Clean cable management for showcase builds: Traditional RGB fans require two cables each (PWM + RGB), creating a rat's nest behind the motherboard tray. With LINK, you run one cable between fans, making builds look cleaner and assembly faster. Compact liquid-cooled systems: At 5.22 mmH₂O static pressure, this fan can efficiently push air through dense radiator fins. It pairs well with 240mm and 360mm AIOs for mainstream gaming rigs. ## Alternatives
Noctua's NF-A12x25 PWM chromax.black.swap (approx. ¥3,500) offers superior noise-to-performance ratio and legendary build quality, but it lacks RGB entirely and is only available in black. If you prioritize absolute silence over aesthetics, Noctua is the better choice. Cooler Master's MasterFan MF120 Halo (approx. ¥4,200) also features dual-ring RGB lighting and similar static pressure, but does not support a unified daisy-chain system like LINK. For users already invested in CORSAIR's ecosystem, the LX120 is easier to integrate.

Things to Consider

The biggest gotcha is the separate purchase requirement for the iCUE LINK System Hub (around ¥5,000). Without the hub, you cannot take advantage of the fan's RGB or daisy-chain capabilities, which largely defeats the purpose of buying this specific model. Noise at full speed is rated at 36 dBA — not whisper-quiet. If you run it at 2,400 RPM continuously, you will hear it. A custom PWM curve that keeps speeds under 1,500 RPM during idle is recommended for silent operation. Finally, if you plan to mix LINK fans with older non-LINK CORSAIR fans, you will need to manage two separate control channels in iCUE. It works, but adds complexity. Plan your fan configuration before buying to avoid compatibility headaches.
