This article covers CORSAIR AR120 RGB 120mm PWMケースファン シングルパック.

Overview

The CORSAIR AR120 RGB is a 120mm PWM case fan that balances quiet operation with solid airflow performance. With a maximum speed of 1,850 RPM, it delivers up to 59 CFM of airflow and 2.8 mmH2O of static pressure, while keeping noise levels at just 27.3 dBA. The fan features eight individually addressable RGB LEDs and comes with a 3-pin ARGB adapter for direct connection to a motherboard's 5V ARGB header. It is also compatible with CORSAIR's iCUE software for unified lighting control across your system. This fan is an excellent entry-to-mid-range choice for builders looking for affordable RGB cooling.

Compatibility Guide

The AR120 RGB fits standard 120mm fan mounts and can be installed on most PC cases, radiators, or heatsinks. It uses a 4-pin PWM connector for speed control, requiring a PWM header on your motherboard. For RGB lighting, a 5V 3-pin ARGB header is necessary – fans with older 12V RGB headers will not work without an adapter. The included ARGB adapter makes connection straightforward on modern motherboards. If you want to use iCUE's advanced lighting effects without a compatible motherboard, an optional iCUE controller (sold separately) can manage up to six fans.

Product Info

Launched in 2023, the CORSAIR AR120 RGB is available in single packs at around ¥3,105. It carries a two-year warranty and sits in the entry-to-mid-range market segment. Performance figures of 59 CFM and 2.8 mmH2O at 27.3 dBA make it a well-rounded option for basic case cooling and light overclocking scenarios. Its low power consumption (typically 1-3W) is negligible for most systems.

Best Use Cases

  • First-time RGB builders: The included ARGB adapter eliminates the need for a separate controller, making this an easy way to add colorful lighting to a new PC. Future expansion with other CORSAIR iCUE components is seamless. - Silence-conscious users: At 27.3 dBA, the fan is nearly inaudible during normal use. It's ideal for quiet home offices, media centers, or any environment where noise pollution matters. - Budget-conscious enthusiasts: For around $20, this fan delivers very good performance and RGB features. Buying a three-pack (if available) can further reduce cost per fan.

Things to Consider

This fan is available only as a 120mm model; 140mm mounting holes are not supported. Ensure your case or radiator has a 120mm fan mount. The RGB requires a 5V ARGB header – older motherboards with 12V RGB headers are not directly compatible. For full iCUE control without motherboard ARGB support, an additional iCUE controller is needed. Also note that while the fan supports PWM control, some motherboards may default to DC voltage regulation; make sure to set the fan header to PWM mode in BIOS. Overall, the AR120 RGB is a solid choice for budget-minded builders who want good airflow and customizable lighting.
