Cooling Fan Alphacool Apex Stealth Metall Aurora 140 mm Chrome 2000 RPM PWM aRGB

Alphacool Apex Stealth Metall Aurora 140 mm is a chrome-finish PC cooling fan with addressable RGB (aRGB) lighting and PWM speed control. Designed for both case airflow and radiator mounting, this 140 mm fan reaches up to 2000 RPM to balance cooling performance and acoustic output. The metal-look frame and blade styling provide a distinct visual accent while the aRGB lighting offers customizable effects compatible with common RGB controllers and motherboards supporting addressable RGB headers.

Advantages

The fan offers PWM-controlled speeds up to 2000 RPM for adaptable cooling depending on system load, enabling quieter operation at low speeds and increased airflow when needed. The chrome appearance gives a premium aesthetic that complements modern builds, while aRGB illumination adds customizable lighting without changing fan performance. The 140 mm form factor is common for both case intake/exhaust and radiators, allowing flexible installation options.

Suitable for

• Gaming PCs that need a balance of airflow and visual lighting
• Workstation builds where larger 140 mm fans reduce noise compared with smaller fans
• Radiator cooling loops in liquid-cooled systems compatible with 140 mm fans
• Systems with motherboards or controllers supporting PWM and addressable RGB headers

When it may not be suitable

This fan may not be suitable for systems that require ultra-low-noise passive cooling, as active fans at higher RPMs still produce audible noise. It is also not suitable for setups without either PWM fan headers or a compatible PWM controller, or for systems lacking an addressable RGB header if aRGB functionality is required.

Key specifications

• Fan size: 140 mm
• Maximum speed: up to 2000 RPM (PWM controlled)
• Lighting: addressable RGB (aRGB)
• Frame finish: chrome/metal-look
• Use cases: case airflow and radiator mounting
• Connector types: PWM fan power connector and aRGB lighting connector (addressable)

How to use

Install the fan in a 140 mm mounting position in your case or on a compatible radiator using the supplied screws or standard fan screws. Connect the fan's power cable to a PWM-capable fan header on the motherboard or to a PWM fan controller to enable automatic speed control. Attach the aRGB cable to an addressable RGB header or compatible controller to manage lighting effects through your motherboard software or external controller. Configure fan curves in BIOS or software to match desired noise and cooling balance.

What to consider before purchase

• Ensure your motherboard or controller has a PWM fan header for speed control
• Confirm presence of an addressable RGB header or compatible controller for aRGB lighting
• Check case or radiator clearance for 140 mm fans and mounting depth with chrome finish

Usage recommendations

For balanced performance, set a moderate fan curve that keeps idle speeds low and increases RPM under higher CPU/GPU loads. If aRGB synchronization is desired, use your motherboard's addressable RGB software for consistent effects across components. For radiator use, pair with fans of the same model to ensure uniform airflow and thermal performance.
