## Summary description

EKL Alpenföhn Wing Boost 4 ARGB reverse is a PWM-controlled cooling fan designed for CPU coolers and case ventilation. It features ARGB lighting for customizable illumination and a reverse-blade design for improved static pressure and airflow direction. Intended for use in PC builds to optimize cooling performance while offering visual lighting effects and straightforward PWM speed control.

## Long description

The EKL Alpenföhn Wing Boost 4 ARGB reverse is a PWM-controlled cooling fan engineered for CPU coolers and case ventilation in desktop PC builds. It combines addressable RGB illumination with a reverse-blade impeller geometry that optimizes static pressure and airflow direction for heatsinks and radiators. The fan is intended to integrate with standard 4-pin PWM headers for automatic speed regulation and with ARGB controllers or motherboard headers for synchronized lighting effects.
Advantages
The reverse-blade design produces higher static pressure compared with conventional fan profiles, improving heat dissipation when mounted on heatsinks or radiators. PWM control enables precise automatic adjustment of fan speed according to CPU or system temperature, reducing noise during low-load operation. Addressable RGB lighting offers customizable colors and effects and can be synchronized with compatible motherboard software or standalone ARGB controllers. The fan’s build supports standard mounting on CPU coolers or case fan positions and is suitable for both single-fan and multi-fan configurations.
Suitable for
 Air-cooled CPU heatsinks requiring concentrated airflow and elevated static pressure
 Radiator mounts in liquid-cooling loops where directional pressure improves thermal transfer
 Case ventilation where synchronized ARGB lighting is desired
 PC builds that use PWM fan headers for automated fan speed control
Key specifications
 Control: 4-pin PWM fan speed control for automatic RPM regulation
 Lighting: Addressable RGB (ARGB) illumination compatible with standard 5V ARGB headers or controllers
 Blade design: Reverse-blade impeller optimized for increased static pressure
 Compatibility: Standard 120 mm fan mounting dimensions for CPU coolers and case positions
 Connector types: Separate PWM power connector and ARGB signal connector for independent control of speed and lighting
How to use
Install the fan using the standard 120 mm mounting holes on the CPU cooler or case. Connect the 4-pin PWM power cable to a compatible motherboard fan header to enable automatic speed control based on system temperature. Connect the ARGB signal cable to a 5V ARGB header or ARGB controller to enable addressable lighting; follow the motherboard or controller documentation for synchronization and effects. Ensure the fan orientation matches the intended airflow direction: the reverse-blade design concentrates airflow toward heatsinks and radiators when mounted with the frame exhaust aligned accordingly.
Usage recommendations
For optimal cooling performance, use the fan in push or pull configurations on heatsinks and radiators and allow PWM control to manage RPMs for a balance between noise and thermal performance. Verify ARGB header voltage and pinout before connecting to avoid incompatible connections. For multi-fan setups, synchronize PWM and ARGB controls through the motherboard or a dedicated controller to maintain consistent airflow and lighting behavior.
