120mm Cooling Fan Pack Kolink Umbra X ARGB PWM — 3 fans, high-performance, model UMBRA X 120MM 3PK

Kolink Umbra X ARGB PWM 120mm fan pack includes three 120 mm case fans engineered for PC chassis and radiator cooling. Each fan supports PWM speed regulation for precise airflow control and features addressable RGB lighting compatible with common motherboard and controller standards. The set is intended to enhance thermal management while offering synchronized lighting effects and quieter operation under typical loads.

Advantages

These 120 mm fans combine adjustable PWM control and ARGB illumination to balance cooling performance and noise. The fans are built to deliver steady airflow through case intakes, exhausts or radiators while ARGB LEDs enable coordinated lighting across multiple fans. Their design aims to reduce acoustic output at lower speeds and provide higher static pressure or airflow when PWM increases fan speed under thermal demand.

Suitable for

• Desktop PC chassis cooling (intake or exhaust)
• All-in-one (AIO) liquid cooler radiator mounting
• Systems requiring synchronized ARGB lighting
• GPU- or CPU-cooled builds with PWM fan headers

Key specifications

• Fan size: 120 mm
• Control: PWM speed control compatible with motherboard fan headers
• Lighting: addressable RGB (ARGB) per fan, compatible with common ARGB controllers
• Pack quantity: three fans
• Mounting: standard 120 mm screw pattern suitable for cases and radiators
• Connector types: 4-pin PWM power connector and 3-pin ARGB connector (one per fan or provided hub)

How to use

Install the fans in the desired orientation inside the case or onto a radiator using the standard 120 mm mounting holes. Connect the 4-pin PWM power connector(s) to available motherboard fan headers or a compatible fan hub to enable automatic speed regulation. Attach the ARGB connectors to a compatible ARGB header or controller to control lighting effects. After installation, configure fan curves and lighting profiles through the motherboard or controller software to match thermal and aesthetic preferences.

Recommendations

For best thermal performance, position two fans as intake at the front and one as exhaust at the rear, or arrange push-pull pairs on radiators when space allows. Ensure ARGB cables are routed to avoid obstructing airflow and verify motherboard compatibility for PWM and ARGB headers before installation.
