Alphacool Apex Stealth Metall Aurora PC fan 140 mm PWM, 2000 rpm, matt black

The Alphacool Apex Stealth Metall Aurora is a 140 mm PWM-controlled PC fan designed for case and radiator cooling. It combines a matt black metal housing with a maximum rotational speed of 2000 rpm to deliver steady airflow for gaming PCs, workstations and custom water-cooling loops. The fan is intended as a replacement or upgrade for existing system fans where a compact 140 mm solution and PWM speed control are required.

Advantages

The fan's matt black metal frame offers increased rigidity and a refined appearance compared with typical plastic housings. PWM control allows automatic speed adjustment based on motherboard or fan controller signals, balancing cooling performance and noise. With up to 2000 rpm the fan can provide stronger airflow and static pressure suitable for use on radiators or in airflow-focused case configurations.

Suitable for

• Case ventilation in mid-tower and full-tower PC builds
• Cooling radiators in water-cooling loops
• Replacing worn or noisy 140 mm system fans
• Setups requiring PWM speed control for automated fan curves

When it may not be suitable

This fan may not be ideal for users who require ultra-low-noise or near-silent operation at all times, since its maximum speed of 2000 rpm is oriented toward stronger airflow rather than passive silence. It may also be unnecessary for compact systems that only accept smaller fan sizes or for applications where LED lighting or specific aesthetic features are required but not provided by this model.

Key specifications

• Size: 140 mm
• Control: PWM (pulse-width modulation)
• Maximum speed: 2000 rpm
• Frame material and finish: metal housing, matt black
• Primary use: case and radiator cooling

How to use

Install the Alphacool Apex Stealth Metall Aurora as you would a standard 140 mm fan, securing it to a case or radiator using compatible screws. Connect the fan's PWM cable to a motherboard PWM header or a dedicated PWM fan controller to enable automatic speed regulation. Configure fan curves in BIOS or software according to desired temperature thresholds to achieve a balance between cooling and acoustics. Ensure airflow orientation matches your system's intake and exhaust layout to maintain optimal thermal performance.

What to consider before purchase

• Verify your case or radiator supports 140 mm fans and has sufficient clearance for a metal-framed unit.
• Confirm availability of a PWM-capable header on the motherboard or use a PWM controller.
• Consider noise tolerance and whether a 2000 rpm maximum meets your acoustic requirements.

Usage recommendations

For radiator mounting, set a moderate fan curve to prioritize static pressure and maintain stable loop temperatures. In case applications, combine intake and exhaust fans to create directed airflow; place this 140 mm fan where its higher rpm can move hot air efficiently without creating turbulence near sensitive components.
