120mm Kolink Umbra X ARGB PWM fan — 1,600 RPM, 24 dB, black

Kolink Umbra X ARGB PWM fan is a 120mm case fan engineered for PC cooling and lighting integration. It combines PWM-controlled motor speed with addressable RGB illumination to provide adjustable airflow and synchronized lighting for modern desktop builds. The fan is optimized for chassis ventilation and can support heatsinks or radiator intake/exhaust duties when installed in appropriate configurations.

Advantages

The Umbra X offers variable speed control through PWM, enabling the fan to run quietly at low loads or increase to higher RPM for greater airflow when needed. Its ARGB lighting connects to standard 3-pin addressable headers for synchronized effects with compatible motherboards or controllers. The 120mm frame and blade design balance airflow and noise, delivering effective ventilation at a reported maximum noise level of 24 dB and a top speed of 1,600 RPM.

Suitable for

• Case ventilation for mid-tower and full-tower desktop systems
• Additional airflow for CPU heatsinks or GPU support in constrained layouts
• Builds that require synchronized ARGB lighting with motherboard or controller headers
• Quiet home or office PCs where low noise and adjustable cooling are desired

Key specifications

• Fan size: 120 mm
• Maximum rotational speed: 1,600 RPM
• Noise level: approximately 24 dB at maximum speed
• Speed control: PWM (pulse-width modulation)
• Lighting: addressable RGB (ARGB) compatible with 3-pin headers
• Color: black frame and blades

How to use

Install the Umbra X fan into a compatible 120 mm mounting location in your PC case using the supplied screws or mounting hardware. Connect the PWM power cable to a motherboard or fan controller header to enable automatic speed regulation based on system temperature. Attach the ARGB cable to an addressable RGB header or controller to enable lighting control and synchronization. Ensure airflow direction aligns with your case cooling plan (intake or exhaust) and secure cabling to avoid contact with the blades.

Recommendations

For balanced cooling and acoustic performance, configure fan curves in the motherboard BIOS or fan control software so the Umbra X runs at lower RPM during idle and ramps up under load. When using multiple fans, maintain consistent airflow orientation and consider pairing with dust filters for prolonged component cleanliness. Verify compatibility of ARGB headers and use appropriate adapters or controllers if necessary.
