Ventoinha de caixa Montech HP140 ARGB PWM 140mm (pack de 3) — ventoinhas de refrigeração ARGB PWM 140mm, pack de 3

Pack of three Montech HP140 ARGB PWM 140mm case fans designed to provide efficient airflow and addressable RGB lighting for desktop PC chassis. Each 140mm fan uses PWM control to adjust rotational speed automatically according to motherboard signals, while ARGB LEDs enable individual-color lighting effects compatible with common RGB controllers. The set supports use as intake, exhaust, or on radiators to assist CPU and GPU cooling in gaming rigs and workstations.

Advantages

The 140mm fan size delivers a balance between static pressure and airflow, helping to move air through dense cases and radiators. PWM support ensures quieter operation at low loads and higher airflow when cooling demand rises. Addressable RGB lighting provides customizable visual effects that integrate with motherboard software or standalone controllers. The three-fan pack offers immediate multi-fan installation for improved case circulation without purchasing individual units separately.

Suitable for

• Cooling mid-tower and full-tower PC cases
• Radiator mounting on 120–140mm-compatible liquid cooling setups
• Improving intake and exhaust airflow in gaming and productivity systems
• Enhancing chassis aesthetics with addressable RGB lighting

Key specifications

• Fan diameter: 140 mm
• Control type: PWM speed control for automatic RPM regulation
• Lighting: addressable RGB (ARGB) per-fan controllable LEDs
• Pack quantity: 3 fans
• Mounting orientation: compatible with intake, exhaust, and radiator positions

How to use

Install the fans into compatible mounting locations in the PC chassis or onto radiator mounting points using the supplied screws. Connect the 4-pin PWM fan connector to a motherboard fan header for automatic speed control, and attach the 3-pin or compatible ARGB connector to a motherboard ARGB header or controller to enable lighting control. Configure fan curves and RGB effects through motherboard software or the external controller to match thermal and visual preferences.

Recommendations

For balanced airflow, use a combination of intake and exhaust placement; avoid blocking airflow paths with cables or components. Set PWM curves to prioritize lower noise during light loads and increased fan speed under heavy CPU/GPU use. When connecting ARGB, verify header compatibility and follow motherboard/controller guidelines to prevent incorrect wiring.
