Pack de ventoinhas para caixa HAVN H14 PWM 140 mm branco — pack de 3, controlo de velocidade PWM, modelo HVN-FS-H1430-01-TRI

Three-pack of HAVN H14 PWM 140 mm white case fans designed for desktop PC cooling. Each fan in this pack supports PWM speed control for accurate RPM regulation, enabling quieter operation at low loads and higher airflow when needed. The fans are intended for chassis mounting, radiator integration, or use as intake and exhaust units to improve overall thermal management in compatible computer cases.

Advantages

HAVN H14 PWM fans combine 140 mm blade geometry with PWM control to balance airflow and noise. The uniform white finish suits many build aesthetics while the included three fans allow for multi-fan configurations without matching concerns. PWM responsiveness provides finer speed adjustments compared with fixed-speed fans, helping reduce noise during light tasks and increase cooling capacity under heavy workloads. Bearings and frame design ensure stable rotation and straightforward screw-mount installation.

Suitable for

• Chassis intake or exhaust mounting in mid-tower and full-tower cases
• Front, top, or rear positions for improved case airflow
• Mounting on compatible 140 mm radiators for liquid cooling loops
• Upgrading stock fans to reduce noise or increase airflow

Key specifications

• Fan size: 140 mm diameter
• Control: PWM (pulse-width modulation) for automatic speed regulation
• Color: white finish on fan frame and blades
• Pack quantity: three identical fans for multi-fan setups
• Mounting: standard 140 mm screw holes for chassis or radiator installation
• Connector type: 4-pin PWM header compatible with standard motherboard fan headers

How to use

Install each fan into the desired case or radiator position using the standard screw holes provided. Connect the 4-pin PWM cable to a compatible motherboard fan header or fan controller that supports PWM. Ensure correct airflow orientation by aligning the intake and exhaust directions according to your case layout. After connecting, configure fan curves in BIOS or software to take advantage of PWM control for temperature-responsive speed adjustments.

Recommendations

Position fans to create a consistent front-to-back or bottom-to-top airflow path, avoid obstructing intake vents, and use PWM-enabled motherboard headers for automatic speed control. Regularly check mounting screws and clean fan blades to maintain optimal airflow and reduce noise over time.
