This article covers ALSEYE N12 ケースファン.

Overview

The ALSEYE N12 case fan set includes three 120mm fans with ARGB lighting and PWM control, plus a compact controller for motherboards lacking an addressable RGB header. Each fan spins up to 1,800 RPM while keeping noise levels at a maximum of 37 dBA, striking a balance between cooling and quiet operation. The semi-translucent white blades and frame give the fans a clean, minimalist look that fits well with modern PC builds. This kit targets entry-level to mid-range users who want customizable lighting without spending a premium. Hydraulic bearings and eight rubber pads help reduce vibration noise, making the N12 a practical choice for budget-conscious builders.

Compatibility Guide

All three fans are standard 120mm × 120mm × 25mm size and can be mounted in most ATX, microATX, and Mini-ITX cases that support 120mm fan positions. Each fan uses a 4-pin PWM power connector for speed control and a 5V 3-pin ARGB connector for lighting. The included SATA-powered controller allows manual lighting adjustments even when the motherboard has no ARGB header. Make sure your power supply has an available SATA power cable for the controller.

Product Info

The ALSEYE N12 fans operate at 700–1,800 RPM via PWM, with an estimated maximum airflow of around 37.5 CFM per fan. Noise is rated at up to 37 dBA. Each fan draws roughly 1.2W from the 12V line. The kit positions itself as an entry-level to mid-range cooling solution, offering ARGB and PWM features at a competitive price point. Warranty details are not explicitly listed, but typical PC fans come with a 1- to 2-year manufacturer warranty.

Best Use Cases

First-time PC builders wanting easy RGB integration: the included controller eliminates the need for an ARGB-capable motherboard. Noise-conscious users building a quiet system: at low speeds the fans are nearly silent, and the rubber pads prevent case resonance. * Budget-oriented upgrades: buying a 3-pack with a controller is more cost-effective than purchasing three individual fans and a separate controller.

Things to Consider

As a lesser-known brand compared to Noctua or be quiet!, long-term durability reviews for the ALSEYE N12 are still limited. The fans’ static pressure and maximum airflow are moderate, so they may not be ideal for radiator use or highly restrictive chassis. For standard intake/exhaust configurations they perform well, but for CPU cooler replacement or high-heat builds, more premium fans might be advisable. The controller wiring can feel slightly fiddly, but the included manual provides clear step-by-step instructions.
