120mm PCCOOLER HALO-RGB-3I1 PC cooling fan, 1000–2000 RPM, RGB lighting

PCCOOLER HALO-RGB-3I1 is a 120 mm PC cooling fan with an adjustable speed range of 1000–2000 RPM and integrated RGB lighting. Designed for case or radiator mounting, this fan delivers directed airflow for CPU or GPU cooling and general system ventilation. The fan balances cooling performance and acoustic characteristics within its specified speed range and supports customizable lighting effects when connected to compatible RGB controllers or motherboard headers.

Advantages

The 120 mm size and variable 1000–2000 RPM range allow the fan to be tuned for lower noise during light loads or increased airflow under heavier workloads. Integrated RGB lighting provides visual customization without adding external LED strips. The fan’s design supports both case intake/exhaust and radiator installation, making it versatile for different cooling configurations. Bearings and blade geometry are optimized to reduce vibration and maintain steady airflow across the rated speed range.

Suitable for

• Case ventilation for mid-tower and full-tower desktop builds
• Mounting on 120 mm radiators for liquid cooling loops
• Supplementary cooling for CPU or GPU heavy-load scenarios
• Systems that require synchronized RGB lighting with motherboard headers or controllers

Key specifications

• Fan diameter: 120 mm
• Rotational speed: 1000–2000 RPM (adjustable)
• Function: case and radiator cooling
• Lighting: integrated RGB LEDs compatible with common RGB control interfaces
• Noise and airflow: balanced for quiet operation at lower speeds and higher airflow at top speeds

How to use

Install the fan in a compatible 120 mm mounting position using the standard screws for case or radiator brackets. Connect the power cable to the appropriate fan header on the motherboard or to a fan controller that supports the fan’s voltage and control method. For RGB lighting, connect the LED cable to a compatible RGB header or controller according to the motherboard or controller pinout. Configure fan speeds and lighting effects through BIOS fan control, software utilities provided by the motherboard manufacturer, or a separate fan/RGB controller.

Recommendations

Position fans to create a consistent airflow path through the case (typically front/bottom intake and rear/top exhaust). When used on radiators, ensure fans are oriented to push or pull air as required for optimal heat dissipation. Monitor temperatures after installation and adjust the 1000–2000 RPM range to achieve the desired balance between cooling performance and noise. Use compatible RGB control software or hardware to synchronize lighting with other system components.
