120 mm PC fan DeepCool FL12 3-in-1 Black, 120×25 mm, 2150 RPM, Fluid Dynamic Bearing, PWM, 55 CFM, 32 dB, pack of 3

The DeepCool FL12-3 in 1 is a 120 mm case fan designed to enhance airflow inside desktop computer enclosures. Finished in black and equipped with a Fluid Dynamic Bearing, this fan is intended to provide quieter operation and a longer service life compared with sleeve-bearing alternatives. It is suitable for general system cooling, case ventilation, and as a replacement or upgrade to help maintain stable component temperatures.

Advantages

The Fluid Dynamic Bearing reduces friction and noise while extending operational lifetime. The 120 mm diameter delivers a balance of airflow and acoustic performance suitable for most mid-tower and full-tower cases. A black finish allows the fan to blend with a variety of system builds. The fan's design aims to improve internal case airflow, lowering CPU, GPU, and other component temperatures when correctly positioned.

Suitable for

• General case ventilation in desktop PCs
• Replacing worn or noisy 120 mm fans
• Upgrading airflow in gaming and workstation builds
• Maintaining optimal temperatures for components under load

Key specifications

• Fan diameter: 120 mm
• Bearing type: Fluid Dynamic Bearing
• Colour: Black
• Weight: 0.498 kg (package or unit weight as provided)
• Form factor: Standard 120 mm case fan

How to use

Install the fan into a compatible 120 mm mounting location in the PC case, ensuring correct airflow direction for intake or exhaust according to your cooling plan. Secure the fan with screws provided or compatible mounting hardware. Connect the fan to an available motherboard fan header or fan controller, observing the correct connector type and voltage. After installation, verify that the fan spins freely and that airflow direction and cable routing do not interfere with other components.

Recommendations

For optimal results, combine intake and exhaust fans to create a coherent airflow path through the case. Periodically clean dust from the fan blades and surrounding filters to maintain airflow and acoustic performance. When replacing fans, match the mounting orientation and connector type to your system to avoid compatibility issues.
