## Long description

The Alphacool Rise Aurora 14 cm fan (Model 24851) provides adjustable cooling performance with integrated digital 5V aRGB lighting. Designed for use on radiators in water-cooling systems or as a case fan, this white 140 mm fan delivers up to 2000 RPM, an airflow of 154.1 m³/h and a maximum static pressure of 2.20 mmH2O. The frame and hub incorporate 24 addressable LEDs and recessed diffusers for even illumination across the entire fan.
Advantages
The fan combines a wide control range via a 4-pin PWM connector with a silent mode that allows regulation down to 0 RPM and automatic start above approximately 600 RPM. At typical low speeds (around 800 RPM) noise is minimal while at maximum speed the fan supplies strong airflow and high static pressure suitable for radiator mounting. Built-in soft foam decouplers on the frame corners reduce vibration transfer to the case, and tear-off edges on the blades help lower aerodynamic noise. The aRGB lighting uses 24 individually addressable 5V LEDs for precise lighting effects with uniform distribution thanks to recessed diffusers.
Suitable for
Mounting on water-cooling radiators
Case ventilation in desktop PCs
Systems requiring adjustable PWM speed control
Key specifications

MPN: 24851, EAN: 4250197248518
How to use
Connect the fan's 4-pin PWM cable to a motherboard fan header or a fan controller to allow speed control from 0 to 2000 RPM. Connect the JST 3-pin aRGB cable to a compatible 5V addressable RGB header or use an available adapter to match a standard 3-pin aRGB plug. Mount the fan to a radiator or case using the supplied screws, ensuring the foam decouplers align with the case mounting points to reduce vibration. Configure PWM curves or a silent mode in BIOS or controller software to define when the fan remains stopped below the automatic start threshold and when it speeds up for cooling.
Usage recommendations
For radiator installations, set a PWM curve that increases fan speed with coolant temperature to balance cooling performance and noise. For case ventilation, using the silent mode or a conservative PWM profile around 800 RPM provides low noise while maintaining adequate airflow. Ensure the 5V aRGB header on the motherboard or controller supports addressable LEDs before connecting the JST cable.
