120mm PC Cooling Fan 4-Pin Blue LED 22.84 CFM 22 dBA Quiet Oil Bearing 30,000 Hours

Maintaining proper airflow inside your computer case is essential for stable performance and component longevity. This 120mm PC cooling fan moves 22.84 cubic feet of air per minute at a low noise level of just 22 dBA, making it a practical choice for quiet builds, office PCs, or media centres. The fan uses an oil seal bearing rated to 30,000 hours of continuous operation, so you can install it and rely on it for years. Whether you are cooling a standard desktop tower or adding intake or exhaust to a compact chassis, this 120x120x25mm fan fits conventional mounting points and runs on standard 12V DC power.

Features and Construction

This fan is built for straightforward installation and consistent performance. Its 4-pin connector provides basic power and speed control, and the 30cm cable length gives enough reach for typical case layouts. The blue LED lighting adds visibility without being overly bright, and alternative colours are available if you prefer a different look.

Material and Build

The frame and blades are made from a plastic composite, which keeps the total weight at only 75 grams. The oil seal bearing is sealed to retain lubrication over time, contributing to the rated 30,000-hour lifespan. No additional details about blade design or frame rigidity are provided in the source text, so no further claims are made here.

Size and Practical Fit

With dimensions of 120 by 120 by 25 millimetres, this fan matches the standard 120mm form factor used in most PC cases, CPU coolers, and radiator mounts. It fits into standard 120mm screw holes spaced 105mm apart and has a thickness of 25mm, which clears most case panels and memory modules.

Uses and Placement

This fan can serve as an intake fan pulling cool air into the case, or as an exhaust fan pushing warm air out. Its moderate static pressure of 1.78mmH2O makes it suitable for open areas of the case and through standard dust filters.

Event or Professional Use

For office PCs, POS systems, or kiosks that run extended hours, the low 22 dBA noise output helps maintain a quiet working environment. The 30,000-hour bearing life means fewer maintenance intervals in commercial settings where downtime is costly.

Everyday Home Use

At home, this fan is well suited to general-purpose desktops used for browsing, streaming, or light gaming. The blue LED colour adds a subtle glow to side-window cases, and the low noise level makes it unobtrusive in living areas or bedrooms.

Benefits and Buying Value

Choosing this fan means getting a balance of airflow, noise control, and longevity at a modest cost. The oil seal bearing is a standard, proven design for case fans in this price and performance bracket.

Reuse and Low Maintenance

Because the bearing is sealed, you do not need to oil it during normal use. Cleaning the blades and frame occasionally with compressed air is sufficient to maintain airflow performance. The fan should last through many years of typical daily use before replacement is needed.

Why Choose This Product

If you need a straightforward, quiet 120mm fan that moves a reliable 22.84 CFM and comes with blue LED illumination, this model covers the basics without extras you might not use. The 30cm cable, 4-pin connector, and lightweight build make installation simple in most standard cases.
