Overview

The Corsair QL140 RGB Single is a 140mm RGB case fan from the QL series, designed to deliver both quiet operation and vibrant lighting. With a maximum speed of 1,250 RPM and noise level of only 20 dBA, it is ideal for silent PC builds while adding aesthetic appeal through iCUE-compatible RGB. This fan uses hydraulic bearings for long-term durability and features anti-vibration rubber pads on all four corners to minimize noise transfer. Its slim 25mm profile fits most standard tower cases, making it suitable for use as intake, exhaust, or radiator fan. Positioned as a mid-range RGB fan, the QL140 RGB Single stands out with its high-visibility lighting design: each of the 34 LEDs per fan is placed on both sides, ensuring 360-degree illumination that shines through the blades.

Compatibility Guide

The QL140 RGB Single uses standard 124mm mounting holes for 140mm fans. It connects via a 3-pin power header; for RGB control, an external iCUE controller (e.g., Lighting Node Core) or a motherboard with a 5V ARGB header is required. The fan is 25mm thick, fitting easily into most mid-tower and full-tower cases. Check clearance when installing alongside large CPU coolers or front-mounted radiators.

Product Info

Released in 2019, the QL140 RGB Single retails for approximately 7,000 JPY. It is available from CORSAIR’s official online store and major retailers like . Warranty covers two years. Power consumption is minimal at 1.25W (12V). The QL series occupies the mid-range tier: it prioritizes RGB visual impact over raw airflow, making it a strong choice for aesthetically-focused builds. Compared to the AF series (high airflow) or LL series (balanced), the QL offers the most immersive lighting experience.

Best Use Cases

Gamers who want silent RGB: The 20 dBA noise level keeps gaming sessions quiet while iCUE lighting syncs with game events or system status for a more immersive setup. First-time PC builders: Simple installation with standard screws, clear cabling, and intuitive iCUE software make this fan a great entry-point for adding RGB without complexity. * Silence-focused builds: With good static pressure and airflow (estimated 60-70 CFM), it efficiently cools while staying nearly inaudible, perfect for home theater PCs or quiet office rigs.

Things to Consider

This single fan unit does not include an RGB controller. If you lack an existing iCUE controller (e.g., Lighting Node Core or Commander Pro), you must purchase one separately to enable lighting control. Additionally, the 3-pin connector means PWM speed control is not supported via the motherboard; you may need a voltage-based fan controller for fine speed tuning. For users prioritizing maximum cooling performance, the CORSAIR AF series (high airflow) or ML series (magnetic levitation) might be more suitable, albeit with less extravagant RGB. The two-year warranty is standard; consider extended coverage for long-term reliability.
