This article covers CORSAIR iCUE LINK RX120 MAX 拡張キット 120mm PWM PCケースファン 30mm厚 シングルパック ブラック CO-9051041-WW.

Overview

The CORSAIR iCUE LINK RX120 MAX is a 30mm-thick 120mm case fan engineered for high-performance cooling. Compared to standard 25mm fans, the extra 5mm delivers significantly higher static pressure, reaching 4.18 mmH2O, while still pushing 71.6 CFM of airflow at 2000 RPM. This fan is part of CORSAIR's iCUE LINK ecosystem, allowing daisy-chaining via the included active connector to reduce cable clutter. The blades use liquid crystal polymer reinforced with glass fiber for durability, and the magnetic dome bearing minimizes friction for quieter operation.

Compatibility Guide

The RX120 MAX requires an iCUE LINK system hub (sold separately) for full software control and daisy-chaining support. It includes an active connector that lets you link directly to adjacent iCUE LINK fans without extra cables. The 30mm thickness may not fit in slim cases or tight front-panel installations; always check your case's maximum fan thickness before purchase. PWM control is available when connected to a motherboard header, and the fan can be configured via CORSAIR iCUE software for custom fan curves and Zero RPM mode.

Product Info

The CORSAIR iCUE LINK RX120 MAX is available now through online retailers like , priced around ¥5,535 for a single pack. It sits in the enthusiast-tier cooling segment, offering benchmark static pressure and seamless integration with the iCUE LINK ecosystem. Specs include: 120mm size, 30mm thickness, 400–2000 RPM speed range, 71.6 CFM maximum airflow, and 4.18 mmH2O maximum static pressure. The fan uses a magnetic dome bearing and LCP+GF blade material. Warranty is standard 2 years from CORSAIR.

Best Use Cases

Radiator cooling: The high static pressure (4.18 mmH2O) makes it ideal for pushing air through dense radiator fins, especially in custom water loops or AIO liquid coolers. iCUE LINK system expansion: If you already have an iCUE LINK hub, adding this fan is nearly cable-free thanks to the active connector. Great for building a tidy, high-performance loop. * High-spec gaming or workstation builds: For systems running hot CPUs/GPUs, this fan provides reliable, high-volume airflow that can reduce overall case temperatures.

Things to Consider

The 30mm thickness can interfere with front-panel clearance in many standard cases. Measure your mounting depth before buying. You must have an iCUE LINK hub (sold separately) to unlock software control and Zero RPM mode. Without the hub, you can still power and PWM control the fan via a standard header. No RGB lighting is included; if you want addressable LEDs, look at the RX120 RGB series. At around ¥5,535 per fan, it's more expensive than standard 25mm fans. The extra cost is justified for high-static-pressure applications, but for basic case ventilation, a cheaper fan may suffice. ## Alternatives
Noctua NF-A12x25 (25mm): Quieter, slightly less static pressure (2.34 mmH2O), and slightly cheaper (~¥4,000 single). Better for air cooling where silence is priority. be quiet! Silent Wings 4 120mm (25mm): Excellent noise levels, moderate static pressure (2.6 mmH2O), ¥3,500. Good all-rounder but lacks the thickness and ecosystem integration. * Thermalright TL-B12 (25mm): Budget-friendly (¥2,000), decent static pressure (1.99 mmH2O). Best value for money, but not in the same performance league as RX120 MAX.
