Fan Silverstone FN80 8 cm Black 27.81 cfm 1.86 mmH2O

The Silverstone FN80 is an 80 mm (80×80×25 mm) computer case fan designed for small form factor (SFF) systems and HTPCs. It delivers up to 27.81 cfm airflow and 1.86 mmH2O static pressure while operating with low noise. The compact size and reliable performance make the FN80 suitable as an exhaust or case fan in compact builds.

Advantages

The seven-blade impeller is engineered to improve airflow while keeping noise levels down. The fan uses a Hydro Dynamic Bearing (HDB) motor assembly for enhanced durability, smoother operation, and extended service life. Its 80 mm footprint ensures compatibility with most SFF and HTPC mounting locations.

Suitable for

• HTPC builds requiring quiet exhaust fans
• Small form factor (SFF) desktop cases
• Cooling tight spaces where an 80 mm fan is needed

How to use

Install the FN80 in the desired 80 mm fan mounting position using the appropriate screws or rubber mounts. Orient the fan so the airflow direction matches your case cooling layout—typically blowing outwards when used as an exhaust. Connect the fan to a compatible header on the motherboard or to a fan controller, ensuring the correct connector type and voltage. Verify secure mounting and clearances before powering the system.

Recommendations

Use the FN80 as an exhaust or case fan in HTPC and SFF systems where space is limited. Regularly check for dust buildup and clean the blades to maintain optimal airflow and bearing life.
