This article covers CORSAIR AR120 RGB 120mm PWMファン ホワイト.

Overview

The CORSAIR AR120 RGB is a 120mm PWM case fan designed for users who want addressable RGB lighting without breaking the bank. Spinning at up to 1,850 RPM, it delivers 59 CFM of airflow with 2.8 mmH2O static pressure. The white fan blades and frame are complemented by eight individually addressable RGB LEDs, giving your build a clean, colorful look. It sits in the budget-to-mid-range segment, making it an excellent choice for first-time builders or anyone looking to add a splash of color to their PC.

Compatibility Guide

Like any standard 120mm fan, the AR120 fits into most PC cases with 120mm mounting points. The 4-pin PWM connector allows precise speed control via the motherboard. For RGB lighting, the included 3-pin ARGB adapter connects directly to a 5V ARGB header on the motherboard. Be aware that older motherboards with 12V RGB headers or 3-pin non-addressable headers won't work with this fan's ARGB implementation. If you want to use Corsair's iCUE software, you'll need an additional iCUE Lighting Node Core (sold separately).

Product Info

Released in 2023, the CORSAIR AR120 RGB is part of Corsair's entry-to-mid-level fan lineup. It comes as a single pack with a 2-year warranty. The retail price hovers around ¥3,000, making it one of the more affordable addressable RGB fans on the market. With a maximum noise level of 27.3 dBA, it's tuned for quiet operation, ideal for home offices or living room PCs. It occupies a sweet spot between Corsair's cheaper non-RGB fans and the premium LL/QL series.

Best Use Cases

  • Budget RGB Gaming Builds: If you're assembling a low-to-mid-range gaming PC on a tight budget, this fan gives you a taste of addressable RGB without needing a dedicated controller. Just plug the ARGB adapter into the motherboard and you're set. - White-Themed Workstations: The white color scheme pairs beautifully with white cases, CPU coolers, and other hardware. Great for streamers or anyone building an aesthetically cohesive desk setup. - Quiet Media PCs: At only 27.3 dBA, the AR120 is quiet enough for a HTPC or server room, where noise matters more than raw airflow. ## Alternatives
    Competitors in the same price bracket include the Noctua NF-P12 redux-1700 (no RGB, but superior airflow and silence) and the Thermaltake Pure 12 ARGB (similar performance with full software control via motherboard). The Noctua is the clear choice for pure performance, while the Thermaltake offers comparable lighting at a similar price. The Corsair AR120 stands out when you already have other Corsair gear and want consistent branding, even though it lacks native iCUE support.

Things to Consider

The biggest catch is the lack of native iCUE control in the single-pack version. Without a separate Corsair controller, you're limited to motherboard-based ARGB control, which means you can't sync lighting with other Corsair peripherals via iCUE. Airflow is average for a 120mm fan; if you have a high-TDP CPU or GPU, consider pairing with a high-static-pressure fan for the radiator. Lastly, buying a three-pack is often more cost-effective than buying three single units, so plan your build accordingly.
