Case fan HAVN PC-Luefter H14 PWM 140 mm White — 1 piece (HVN-FS-H1430-01)

HAVN PC-Luefter H14 PWM 140 mm White is a single 140 mm case fan designed for desktop computer cooling. The fan features PWM control for precise speed adjustment, allowing users to balance airflow and acoustic levels. Its white frame and blades fit a range of case interiors and can be mounted as intake or exhaust to improve ventilation and temperature regulation of internal components.

Advantages

The PWM control provides automatic or motherboard-managed speed regulation to reduce noise at low loads and increase airflow when cooling demand rises. The 140 mm form factor delivers higher airflow at lower rotational speeds compared with smaller fans, enabling effective heat dissipation with reduced vibration and acoustic footprint. The fan’s neutral white finish integrates with common system color schemes and simplifies orientation for installation.

Suitable for

• Case cooling in mid-tower and full-tower desktop PCs
• Intake or exhaust fan positions to improve airflow
• Systems where a balance of airflow and low noise is required
• Replacing a worn or noisy 140 mm case fan

Key specifications

• Form factor: 140 mm case fan
• Control type: PWM (pulse-width modulation) for variable speed
• Color: white frame and blades
• Mounting: standard 140 mm mounting hole pattern for PC cases
• Airflow purpose: general-purpose intake or exhaust ventilation

How to use

Install the fan in a compatible 140 mm mounting position inside the PC case using appropriate screws. Connect the fan’s PWM cable to the motherboard or a PWM-capable fan controller header to enable automatic speed control. Orient the fan so that airflow direction matches the desired intake or exhaust configuration, and secure any cable routing to avoid contact with blades or other components. After installation, verify in BIOS or system software that the fan is detected and configure speed profiles if required.

Recommendations

For optimal cooling, combine this 140 mm PWM fan with complementary fans to create a balanced airflow path (intake vs. exhaust). Keep fan blades and surrounding filters clean to maintain performance and check that the PWM header supports the fan’s standard control range. Use manufacturer- or motherboard-provided monitoring tools to set temperature-based fan curves that minimize noise while ensuring adequate cooling.

HAVN PC-Luefter H14 PWM is intended for users seeking a straightforward, PWM-controlled 140 mm fan to enhance case ventilation and manage system temperatures with adaptable noise levels.
