120mm PCCOOLER FX-120-3 case fan, 1200 RPM, 18 dB

PCCOOLER FX-120-3 is a 120mm case fan designed to provide steady airflow inside desktop computer enclosures. With a maximum rotational speed of 1200 RPM and a rated noise level of 18 dB, the fan is intended for applications where moderate cooling and low acoustic output are required. Its compact 120mm size makes it compatible with standard fan mounts for cases and some radiators, and it can also serve as a replacement fan to restore or improve cooling performance.

Advantages

The FX-120-3 balances airflow and quiet operation, offering modest cooling capacity without producing significant noise. Its 120mm form factor ensures broad compatibility with PC cases and common mounting locations. The low maximum speed reduces wear and energy consumption compared with higher-RPM alternatives, supporting prolonged component life and stable temperatures for typical desktop workloads.

Suitable for

• Small to mid-tower desktop computer cases that accept 120mm fans
• Quiet home or office PCs where low noise is a priority
• Use as a replacement fan for case intake or exhaust positions
• Cooling of air-cooled components and improving internal airflow

Key specifications

• Fan size: 120 mm
• Maximum rotational speed: 1200 RPM
• Noise level: 18 dB (maximum)
• Typical application: case ventilation and radiator compatibility

How to use

Install the PCCOOLER FX-120-3 into any standard 120mm fan mount using the screws supplied with your case or fan kit. Orient the fan so airflow direction matches your intended intake or exhaust configuration; most fans indicate airflow direction on the frame. Connect the fan connector to an available motherboard fan header or to an appropriate power source following your system’s wiring and control options. Verify that the fan spins freely and that cable routing does not obstruct blades or other components.

Recommendations

For stable, low-noise operation, mount the fan on firm surfaces and use vibration-dampening mounts if available. Place the fan to promote a balanced airflow path through the case (intake at front/bottom, exhaust at rear/top) and avoid blocking vents. Regularly clean dust from the blades to preserve airflow and acoustic performance.
