Overview

The SilverStone SST-FN81 is an 80mm case fan designed for supplemental cooling in tight spaces. It suits builders needing quiet airflow for compact chassis or targeted component cooling.

Compact Design

The fan uses an 80mm square frame that is 25mm thick. It matches standard 80mm mounting patterns found on many cases, coolers, and radiators. The black frame and blades create a uniform look.

Performance Profile

At full speed the motor spins at 2050 RPM and moves 42 cubic meters of air per hour. The acoustic output measures 23.5 dB(A), keeping background noise low. A starting voltage of 7V allows the fan to spin up from very low PWM or voltage settings.

Connectivity and Control

A three-pin connector provides power and tachometer feedback. Speed can be managed through motherboard voltage control or fan controllers. No RGB lighting or additional cables are included.
