Set of Three 120mm RGB PC Case Fans with Hydraulic Bearing and Adjustable Speed

This product is a complete set of three 120mm RGB fans designed for installation in a desktop computer case. Their primary function is to move air through the chassis, drawing in cool air and expelling warm air generated by components like the CPU and GPU. Each fan in the set operates on hydraulic bearing technology and offers a user-adjustable speed range. This allows for a balance between effective cooling, with a maximum airflow of 54.51 CFM per fan, and quieter operation, with a maximum noise output of 31.4 decibels. The set provides a coordinated cooling solution with synchronised RGB lighting effects, all housed within a standard 120mm by 120mm by 25mm frame made from ABS plastic.

Features and Construction

This fan set is built around specific technical specifications and a standardised form factor for reliable PC case integration. The following details outline its core construction and performance parameters.

Material and Build

The structural frame and blades of each fan are manufactured from ABS plastic, a common material choice for computer fans due to its rigidity and light weight. The key mechanical component is the hydraulic bearing, which is integrated into the fan's design to facilitate rotation. This bearing type contributes to the fan's operational characteristics, including its specified noise profile. The set is supplied in a unified black colour across all three units.

Size and Practical Fit

Each individual fan adheres to the 120mm square form factor, with precise external dimensions of 120mm in length, 120mm in width, and a thickness (or height) of 25mm. This is a standard size supported by the majority of modern PC cases, which feature pre-cut mounting points for 120mm fans on the front, rear, top, or side panels. The 25mm depth is the typical profile for such case fans. The product is supplied as a complete set of three identical fans, configured as an 'FRGB 3 Set', meaning they are intended to be used together with synchronised addressable RGB lighting.

Uses and Placement

This set of fans is intended for active thermal management within a desktop computer enclosure. Strategic placement is key to creating an effective airflow path that cools internal components.

Event or Professional Use

For systems under sustained heavy loads, such as during gaming, video rendering, or computational work, maintaining low component temperatures is critical. Installing multiple fans from this set allows for the creation of a high-airflow configuration. Users can set the fan speed towards the higher end of its 1000-1800 RPM range to maximise the 54.51 CFM airflow when cooling demand is greatest, helping to prevent thermal throttling and maintain system stability during extended use.

Everyday Home Use

For general home and office computing where noise levels are a greater concern, the adjustable speed function offers flexibility. Fans can be run at lower RPMs within the 1000-1800 range, which reduces their noise output towards the lower end of their 31.4 dBA maximum rating. This makes for a quieter computing environment during web browsing, document work, or media playback, while still providing essential baseline airflow to keep components adequately cool.

Benefits and Buying Value

Choosing this three-fan set provides specific practical advantages related to system building, maintenance, and performance tuning compared to sourcing fans individually.

Reuse and Low Maintenance

The use of hydraulic bearings in the fan design is associated with a potential for longer service life and consistent performance with minimal maintenance. The fans' construction from ABS plastic also makes them straightforward to clean; accumulated dust can be wiped from the blades and frame to restore unimpeded airflow. As a complete matched set, there is no need to source compatible fans separately for a multi-fan setup, simplifying both the initial installation and any future system upgrades or rebuilds.

Why Choose This Product

This product offers a coordinated cooling solution with clearly defined specifications. The key decision factors are the inclusion of three matched 120mm fans, their adjustable 1000-1800 RPM speed range for balancing noise and cooling, and their quantified maximum performance metrics of 54.51 CFM airflow and 31.4 dBA noise. For a user seeking to install or upgrade case fans in multiple locations simultaneously, this set provides a uniform look and performance profile, backed by the stated hydraulic bearing technology and standard dimensions for broad case compatibility.
