Alphacool Apex Stealth Metall Aurora fan 140x140x25mm 2000 RPM PWM aRGB white

The Alphacool Apex Stealth Metall Aurora fan is a 140 x 140 x 25 mm white PC fan designed for case ventilation and radiator cooling. With a maximum speed of 2000 RPM and PWM control, the fan delivers adjustable airflow while maintaining low noise levels. Addressable RGB (aRGB) lighting provides customizable illumination that can be synchronized with compatible controllers. The metal-reinforced frame and bearing design emphasize durability for continuous operation in desktop systems.

Advantages

The fan combines PWM modulation for precise speed and noise control with a 2000 RPM maximum for strong airflow when needed. Addressable RGB lighting offers per-LED illumination options for integration into modern PC builds. The metal-reinforced construction improves structural rigidity and long-term reliability compared with standard plastic-frame fans. Its 140 mm form factor and 25 mm thickness make it compatible with many cases and radiators that support 140 mm fans.

Suitable for

• Case airflow improvement in mid-tower and full-tower desktops
• Mounting on 140 mm radiators for CPU or GPU liquid cooling loops
• Systems requiring PWM fan speed control for noise/temperature balancing
• Builds that use addressable RGB lighting for coordinated illumination

When it may not be suitable

This fan may not be suitable for enclosures that only accept smaller fan sizes (e.g., 120 mm) or for setups that require ultra-low-profile fans thinner than 25 mm. Systems without a PWM-capable header or without an aRGB controller will still run the fan but will not be able to use full speed regulation or addressable lighting features without additional adapters or controllers.

Key specifications

• Size: 140 x 140 x 25 mm
• Maximum speed: 2000 RPM
• Control: PWM speed control
• Lighting: Addressable RGB (aRGB)
• Color: White frame and blades
• Design: Metal-reinforced frame for increased rigidity

How to use

Install the fan in a 140 mm mounting location in the case or on a compatible radiator using the supplied screws or standard 140 mm fan screws. Connect the PWM power cable to a motherboard header that supports PWM for automatic speed control, or use a fan controller that accepts PWM input. Connect the aRGB cable to an addressable RGB header or controller to enable lighting effects; if an aRGB header is not available, use a compatible controller or adapter. After installation, verify orientation for correct airflow direction and configure fan curves and lighting in firmware or controller software.

What to consider before purchase

• Check that your case or radiator has 140 mm mounting points and 25 mm clearance.
• Ensure your motherboard or fan controller supports PWM if you want automatic speed regulation.
• Confirm you have an addressable RGB header or a compatible controller for aRGB functionality.
• Consider airflow and static pressure needs depending on whether the fan is used for case ventilation or radiator cooling.

Usage recommendations

For balanced performance and low noise, configure the PWM curve in BIOS or fan control software to keep idle speeds low and allow higher RPMs under load. When using the fan on radiators, prioritize static pressure by arranging fans in push or pull configurations and maintain clearance from obstructions. Use the aRGB controller or motherboard software to synchronize lighting with other components for consistent visual results.
