## Long description

Set of three HAVN H12 PWM 120 mm black case fans designed for standard 120 mm PC mounts. Each fan supports PWM speed control to provide variable RPM according to motherboard or fan controller signals. The fans are intended to improve system airflow and reduce temperatures for components such as the CPU area, GPU and internal case hot spots. The set is supplied with power and speed control compatibility for typical desktop system installations and allows continuous operation in 24/7 environments when installed according to system specifications.
Advantages
HAVN H12 PWM fans combine a compact 120 mm footprint with PWM-controlled speed for flexible cooling and quieter operation at lower loads. The three-fan set enables matched airflow performance across intake and exhaust positions, simplifying balanced ventilation planning. Their standard mounting size and typical power connector compatibility make them easy to install in most desktop enclosures without the need for adapter accessories.
Suitable for
 General PC case cooling (intake and exhaust)
 Improving airflow around CPU and GPU zones
 Upgrading or replacing existing 120 mm fans
 Systems where PWM-controlled variable fan speeds are required
Key specifications
 Form factor: 120 mm fan size suitable for standard case mounts
 Speed control: PWM (Pulse Width Modulation) compatible for automatic RPM adjustment
 Set quantity: three identical fans for multi-fan setups
 Color: black frame and blades
 Intended use: case ventilation for desktop computer systems
How to use
Install each HAVN H12 PWM fan into the desired 120 mm mounting positions in the computer case, observing airflow direction indicators if present. Connect the three-pin or four-pin PWM connectors to the motherboard fan headers or a compatible fan controller to enable speed regulation by system temperature or manual fan curves. Secure the fans with mounting screws provided by the case or fan manufacturer, ensure cable routing does not obstruct other components, and verify rotation and RPM feedback in the system BIOS or monitoring software after powering on.
Usage recommendations
For balanced airflow, use combinations of intake and exhaust placements and configure PWM control via motherboard software or BIOS. Periodically clean fan blades and surrounding dust filters to maintain performance and avoid excessive vibration. If connecting multiple fans to a single header, verify the motherboard header current rating or use a powered fan hub to prevent overloading.
