RAIJINTEK IRIS 14 Rainbow RGB LED fan 140mm, 2-piece set with controller

RAIJINTEK IRIS 14 Rainbow is a 140mm RGB LED PC cooling fan sold as a two-piece set with a dedicated controller. Designed for case or radiator cooling, the IRIS 14 Rainbow provides airflow and ventilation while integrating RGB lighting that can be controlled and synchronized between the two fans using the included controller. The fan is intended for desktop computer builds where quiet operation, effective air movement, and customizable lighting are required.

Advantages

The IRIS 14 Rainbow set combines two 140mm fans with an integrated RGB system and a separate controller, allowing synchronized lighting without additional motherboard software. The fan design balances static pressure and airflow for versatile use on radiators and chassis intakes/exhausts. Noise levels are managed to maintain quieter operation under typical loads, and the included controller simplifies setup and lighting adjustments for both fans simultaneously.

Suitable for

• Case cooling for mid-tower and full-tower desktop systems
• Radiator cooling in air- or liquid-cooled systems
• Aesthetic RGB lighting for gaming and productivity builds
• Systems requiring synchronized lighting without motherboard RGB headers

Key specifications

• Fan size: 140 mm
• Set contents: two fans and one dedicated controller
• Lighting: multi-color RGB LED illumination with multiple modes
• Compatibility: designed for standard 140 mm mounting in PC cases and radiators
• Intended performance: balanced airflow and static pressure suitable for case ventilation and radiator usage

How to use

Install each 140 mm fan into the case or on the radiator using standard mounting screws, ensuring correct airflow orientation for intake or exhaust. Connect the fans to the included controller according to the provided cable layout and mount the controller in an accessible location inside the case. Use the controller interface to select lighting modes and synchronize effects across both fans. Connect power for the fans and controller to the system power as instructed by the installation guide.

Recommendations

For best results, position the IRIS 14 Rainbow fans where they complement your case airflow plan (typically front or bottom for intake, top or rear for exhaust) and keep fan airflow unobstructed by cables. When used on radiators, confirm airflow direction to support heat dissipation. Use the included controller to set lighting modes that suit your build and verify power connections before first startup.
