120 mm PC case fan set HAVN H12 PWM, white, 3-piece

Set of three 120 mm HAVN H12 PWM case fans in white designed for use in desktop computer enclosures. Each fan features PWM control for automatic speed adjustment to balance airflow and acoustic performance. The fans are suitable for intake or exhaust configurations and provide continuous airflow to support CPU and component cooling. Installation uses a standard 4-pin PWM connector and conventional mounting holes compatible with most PC cases.

Advantages

HAVN H12 PWM fans combine consistent airflow with automatic speed regulation through PWM, which helps maintain targeted temperatures while reducing unnecessary noise. The 120 mm frame size delivers a balance of static pressure and airflow appropriate for general-purpose case ventilation. The white finish integrates visually with light-themed builds and the three-fan set simplifies achieving multi-fan configurations without mixing models.

Suitable for

• General PC case ventilation (intake and exhaust)
• Cooling mid-tower and full-tower desktop systems
• Supporting CPU cooler or GPU thermal management by improving case airflow
• Replacing or upgrading existing 120 mm case fans for quieter, automated control

Key specifications

• Fan size: 120 mm diameter
• Control type: PWM (pulse-width modulation) 4-pin control
• Set quantity: 3 fans
• Color: white frame and blades
• Connector: standard 4-pin PWM connector for motherboard or fan hub
• Mounting: standard 4-hole mounting pattern for 120 mm fans

How to use

Mount the fans in the chosen positions inside the PC case using the standard screw holes; observe airflow direction indicated on the fan housing to set intake or exhaust orientation. Connect each fan to a motherboard fan header or a PWM-capable fan hub using the 4-pin connector to enable automatic speed control. Configure fan curves in the system BIOS or through motherboard software to match desired cooling and noise preferences. Ensure cables are routed to avoid contact with blades and to maintain unobstructed airflow paths.

Recommendations

For balanced case cooling, arrange at least one fan as intake at the front and one as exhaust at the rear or top. Use PWM control to set conservative fan curves that increase speed under load and reduce it during idle periods to minimize noise. Regularly clean fans and dust filters to sustain airflow performance.
