Size: A 120mm case fan has dimensions of 120mm x 120mm, suitable for most standard ATX computer cases.

Airflow (CFM - Cubic Feet per Minute): Airflow represents the volume of air the fan can move in a minute. Higher CFM values indicate better cooling performance.

Static Pressure: Fans with higher static pressure are suitable for use with radiators and heatsinks, as they can push air through densely packed components.

Noise Level (dBA - decibels): Fans vary in noise levels, with quieter fans being preferred for a peaceful computing environment. Look for models with lower dBA ratings if noise is a concern.

Speed Control: Fans with adjustable speed settings, like PWM (Pulse Width Modulation), allow you to fine-tune the fan's performance and noise level.

Bearing Type: Common bearing types include sleeve, ball, and fluid dynamic bearings. Fans with better bearings tend to be more reliable and durable.

LED Lighting: Some 120mm case fans come with LED lighting for aesthetic customization. Choose the style and color that matches your PC's theme.

Connector Type: Ensure the fan's connector type (e.g., 3-pin or 4-pin) is compatible with your motherboard or fan controller.

Effective Cooling: 120mm case fans provide excellent cooling, helping to maintain the internal temperature of your computer within the appropriate range, preventing overheating.

Improved Airflow: Installing case fans enhances airflow, ensuring air passes through the motherboard, GPU, hard drives, and other components, helping to reduce temperatures.

Dust Reduction: Fans can reduce the accumulation of dust inside your computer, aiding in maintaining a clean system.

Noise Control: High-quality fans typically offer effective cooling while maintaining relatively low noise levels, contributing to a quieter computing environment.

Enhanced System Stability: By keeping temperatures in check, case fans help improve the stability and performance of your computer system.

120mm case fans are widely used in:

Computer Cooling: Installed inside computer cases to lower internal temperatures, maintaining the system within an appropriate temperature range.

Gaming Computers: Gaming PCs often require additional cooling to handle the heat generated during high-performance gaming.

Workstations: Workstations for professional applications benefit from effective cooling to ensure system stability during extended work sessions.

Servers: Servers typically require robust cooling to ensure continuous, stable operation.

DIY Projects: 120mm case fans can also be used in various DIY projects, such as custom cooling solutions or case modifications.
