This article covers CORSAIR RS140 ARGB PWM 140mm PCケースファン デイジーチェーン対応 シングルパック ブラック CO-9050182-WW.

Overview

The CORSAIR RS140 ARGB PWM is a 140mm PC case fan that packs eight addressable RGB LEDs into a single package. It uses a +5V ARGB connector for motherboard-based lighting control and a 4-pin PWM connector for speed regulation. With a maximum speed of 1,700 RPM and airflow rated at 95.5 CFM, it delivers solid mid-range performance for a 140mm fan. What sets the RS140 apart is CORSAIR's AirGuide technology, which focuses the airflow into a concentrated stream rather than letting it scatter. This makes the fan particularly effective when mounted on radiators or CPU coolers. The Zero RPM mode is another highlight: under low load, the fan can stop completely, enabling near-silent operation during idle or light tasks. Daisy-chaining support is a major convenience feature. Both the ARGB and power cables can be linked between multiple fans, so you only need one motherboard header for each signal type even when running several fans. This simplifies cable management and keeps the build looking clean.

Compatibility Guide

The RS140 ARGB PWM fits standard 140mm fan mounting holes, making it compatible with most ATX, Micro-ATX, and Mini-ITX cases that support 140mm fans. Always check your case specifications to confirm available fan positions. The ARGB connector is a +5V 3-pin addressable RGB header. Your motherboard must have a compatible +5V ARGB header; do not connect it to a 12V RGB (4-pin) header, as this may damage the fan. The PWM control requires a 4-pin header, though 3-pin voltage control will also work. When daisy-chaining, connect the fans together with the included cables, then run a single cable from the last fan to the motherboard. This reduces header usage to just one ARGB and one PWM header, regardless of how many fans you install.

Product Info

The CORSAIR RS140 ARGB PWM launched in 2024 and sits in the mid-range segment of the case fan market. It offers a balanced feature set: addressable RGB, PWM control, Zero RPM mode, and daisy-chain capability, all at a reasonable price point. Noise level is rated at a maximum of 36 dBA, which is fairly quiet even at full speed. The AirGuide technology focuses airflow for better cooling on targeted components like CPU coolers and radiators. CORSAIR backs the fan with a standard 2-year warranty. It is available as a single-pack unit (model CO-9050182-WW) and also in a three-pack bundle. Major online retailers like carry the product.

Best Use Cases

RGB-focused gaming builds: With eight addressable LEDs, the RS140 can create vibrant lighting effects controlled by your motherboard's software. Ideal for builders who want a colorful interior without investing in a proprietary ecosystem. Not recommended for users who prefer a stealth, non-RGB aesthetic. Quiet PC enthusiasts: Zero RPM mode stops the fan entirely under low load, making it perfect for silent home-theater PCs or office machines where noise is a concern. However, if your system runs under heavy load most of the time, the Zero RPM benefit is minimal, and a higher-static-pressure fan might serve you better. * Cable-management-conscious builders: Daisy-chaining drastically reduces cable clutter. This is a huge plus for first-time builders or anyone who values a tidy interior. If you already own non-daisy-chain fans and plan to mix them, you'll need to run separate cables for each fan.

Things to Consider

The RS140 ARGB PWM delivers solid mid-range performance, but it doesn't lead the pack in any single metric. Enthusiasts seeking maximum airflow or absolute silence may prefer specialized options like the Noctua NF-A14 or be quiet! Silent Wings 4, which offer higher CFM or lower noise levels. ARGB compatibility is limited to +5V 3-pin headers. If your motherboard only has 12V RGB headers, you will need an adapter or a different fan. Always verify your motherboard's RGB header type before purchasing. While daisy-chaining is convenient, there is a practical limit to how many fans you can chain. CORSAIR does not specify a hard limit, but chaining more than 3-4 fans may cause reduced LED brightness or unstable PWM control. For larger builds, consider using a separate fan hub or controller. ## FAQ
Q: Can I use this fan as a CPU cooler fan replacement? A: Yes, if your CPU cooler supports 140mm fans, you can replace the stock fan with the RS140. However, it may not deliver the same static pressure as a fan specifically designed for CPU cooling. It works well on radiators thanks to AirGuide technology. Q: What is the difference between the single pack and the three-pack? A: The three-pack includes three fans plus additional daisy-chain cables and sometimes a controller. The single pack contains one fan only. If you need multiple fans, the three-pack offers better value. Daisy-chaining works with both packs. Q: Does this fan work with CORSAIR iCUE software? A: No, the RS140 ARGB PWM is not iCUE-compatibl
