Overclocking Three RGB Chassis Fan Set: 12cm Black ABS Fans with Hydraulic Bearings

This set of three identical RGB chassis fans is designed for upgrading the airflow within standard ATX, micro-ATX, or other PC case formats. Each fan in the black set features a 12cm square frame measuring 120mm by 120mm by 25mm thick, a common size for case front, rear, top, or bottom mounting positions, as well as for use with many liquid cooling radiators. The fans utilise a hydraulic bearing system, a design choice aimed at providing smooth rotation over time. With an adjustable speed range from 1000 to 1800 rotations per minute (RPM), and a stated tolerance of ±10%, these fans offer a degree of customisation for balancing cooling performance with the acoustic environment of your workspace or gaming setup.

Features and Construction

The construction and specifications of these fans are centred on providing reliable case ventilation. The key figures provided allow for an understanding of their potential cooling contribution and operational characteristics within a system.

Material and Build

The fans are built using ABS plastic for the main frame structure and the blades. This material provides the necessary rigidity to maintain the fan's shape and blade pitch during operation, which is important for consistent airflow. The central element is the hydraulic bearing, which supports the fan's rotor. This bearing type is filled with lubricant for its operational lifespan and is designed to offer a balance of longevity and quiet running, contributing to the stated maximum noise level of 31.4 decibels (dBA). It is important to note that the noise specification carries a ±10% manufacturing tolerance.

Size and Practical Fit

The primary dimension for installation is the 120mm by 120mm square frame, which conforms to the nearly universal 12cm fan standard. The 25mm thickness is also standard for many case fans, ensuring compatibility with typical fan mounts and screw holes. This size makes the trio suitable for replacing existing 120mm fans or populating empty fan grilles in a wide variety of computer cases. When planning installation, ensure your case has sufficient depth behind the mounting point to accommodate the 25mm profile, plus the space taken by wiring and connectors.

Uses and Placement

A set of three fans provides flexibility for configuring case airflow. They can be deployed together in a single zone or spread throughout the chassis to establish a directional air path, typically front-to-back or bottom-to-top, to efficiently remove heat generated by the CPU, GPU, and other components.

Gaming and Performance PC Builds

In a gaming or high-performance PC, effective cooling is crucial to maintain component stability under load and can help sustain higher clock speeds. These fans, with their maximum air flow rating of 54.51 cubic feet per minute (CFM) per fan, are geared towards moving a tangible volume of air. Using the adjustable speed feature via motherboard fan control or a manual controller, you can set the fans to run faster during intensive gaming or rendering sessions for increased cooling, and slower during idle periods for quieter operation.

Everyday System and Upgrade Use

For a general office PC, media centre, or a system upgrade where existing fans may be failing or insufficient, this three-pack offers a straightforward solution. Installing them can improve baseline airflow, which helps with overall system temperature management and longevity. The RGB lighting adds a visual element, but the core function remains moving air. The hydraulic bearings are intended for continuous use, making them suitable for systems that run for extended periods.

Benefits and Buying Value

The value of this product lies in its specification-matched performance for case cooling and the practicality of a multi-fan pack. The provided data allows for an informed comparison against your system's cooling requirements.

Reuse and Low Maintenance

The hydraulic bearing is sealed and lubricated, designed to operate without user intervention for its service life. This translates to a fit-and-forget installation for most users. The robust ABS construction means the fans can be cleaned of dust with compressed air or a soft brush without damage, and reinstalled in future builds, as the 120mm size remains a long-standing standard in PC hardware.

Why Choose This Product

This fan set is a match for users who need to source multiple 120mm fans of the same model for a uniform look and consistent performance. The clearly stated parameters—the 54.51 CFM maximum airflow, the 1000-1800 RPM speed range (±10%), and the 31.4 dBA (±10%) maximum noise—provide concrete metrics for decision-making. If your requirement is for a set of basic, functional RGB case fans with published specifications for airflow and noise, and compatibility with standard 12cm mounts, this three-pack presents a clear option.
