Silverstone Technology SF160B 160mm case fan

160mm PWM fan for 140mm mounts

This 160mm case fan uses standard 140mm mounting holes to deliver a larger cooling surface while fitting existing chassis layouts. A fluid dynamic bearing and three-phase, six-pole motor provide smooth, quiet operation across the full speed range. The Shark Force blade profile is designed to reduce noise and improve airflow performance. Modular cabling simplifies routing and connection inside the build.

Suited for PWM-controlled cooling on 140mm mounts

Builders who want a single fan that can run quietly at low loads and reach 1600 RPM under heavy demand will benefit from the wide PWM range. The modular cable helps keep cable management tidy in compact or high-airflow configurations. This fan is not for systems that lack 140mm mounting points or that require a fixed-voltage, non-PWM connection. It is also not for setups needing multiple fans in a single pack.

160mm blade on 140mm mounting pattern

The defining specification is the 160mm blade diameter paired with 140mm screw spacing, which increases the cooling area without changing the mounting footprint. This combination determines whether the fan can be installed in a given case and how much air it can move relative to a standard 140mm unit.
