Fan Silverstone FHS 80X 8 cm Black 83.66 cfm 50.77 mmH2O

The Silverstone FHS 80X is an 8 cm case fan engineered for high-performance cooling in desktop PC builds. With a giant-bladed 38 mm thickness design, the fan delivers increased airflow and static pressure compared to standard 25 mm fans, making it suitable for situations that require stronger air movement or better push through restrictive environments. The fan is finished in black and measures 80 × 80 × 38 mm.

Advantages

The oversized 38 mm blade assembly provides extreme performance by increasing overall airflow and pressure. The fan supports PWM control across a wide 2,000–10,000 RPM range, allowing precise speed adjustment to balance cooling and noise. High rated airflow (83.66 cfm) and high static pressure (50.77 mmH2O) make the fan effective for both case ventilation and restricted-airflow configurations such as heatsinks or radiators.

Suitable for

• General case ventilation in compact or standard PC cases
• Cooling around heatsinks and dense component layouts
• Use on radiators or locations with restricted airflow where high static pressure is needed

How to use

Install the fan in a compatible 80 mm mounting location using the provided screws or standard fan mounts. Connect the PWM cable to a motherboard or fan controller header that supports PWM for variable speed control. Ensure the airflow direction matches the intended flow path in the case (intake or exhaust). Verify secure mounting to minimize vibration and check BIOS or controller settings to configure the PWM curve or target RPM range.

Recommendations

For optimal results, use the fan where higher static pressure is required—such as behind radiators, on heatsinks, or in cramped case sections. Configure PWM limits to avoid excessive speeds for continuous operation; monitor temperatures and adjust the fan curve to balance cooling performance and noise.
