Ventilator Silverstone FHS 120X 12 cm zwart 1000-4000 tpm

The Silverstone FHS 120X is a 120 mm case cooling fan engineered for high-efficiency industrial-style thermal management in PC systems. With a thicker 38 mm frame and giant-bladed impeller, it delivers increased airflow and static pressure compared to a standard 120 mm fan while covering a wide PWM-controlled speed range from 1,000 to 4,000 RPM. The model is finished in black and is suitable for builds requiring strong, concentrated airflow and elevated cooling performance.

Advantages

The fan's 38 mm total thickness and large blades improve overall performance over standard fans by producing higher static pressure and enhanced airflow. PWM control enables tailored performance on demand across a broad 1,000–4,000 RPM range, allowing efficient regulation of cooling vs. noise. The compact 120 mm form factor and black color make it compatible with most PC cases and cooling configurations.

Suitable for

• High-performance PC cases with restricted airflow
• Radiator or heatsink installations requiring high static pressure
• Workstations and gaming rigs needing intensive cooling
• Custom builds where PWM speed control is required

How to use

Install the Silverstone FHS 120X in a compatible 120 mm mounting location, ensuring the airflow direction matches your case airflow plan. Connect the fan to a motherboard or fan controller PWM header to enable speed regulation between 1,000 and 4,000 RPM. Secure the fan with appropriate screws or vibration-damping mounts and route the cable to avoid contact with moving parts.

Recommendations

For radiator or heatsink installation, position the fan to push or pull air through fins depending on your cooling layout. Use PWM control to balance cooling performance and acoustic levels—run at higher RPM during heavy loads and reduce RPM for quieter idle operation. Verify that your fan header supports the maximum current draw and PWM range of this high-performance fan.
