A set of three 120mm PWM fans featuring reverse blade orientation for side or bottom intake mounting. Suited for showcase builds needing directed airflow and quiet operation.
Reverse blade orientation directs intake airflow precisely at side or bottom panel positions. This layout suits glass-panel or open-frame cases where the fan front remains visible while pulling cool air into specific zones.
Seven aerodynamically shaped blades reduce turbulence at speed. The low minimum RPM allows near-silent running during light loads, while the 1500 RPM ceiling delivers 47.1 CFM at a maximum of 28.5 dBA.
A rifle bearing supports up to 80,000 hours of continuous operation. The all-black 120mm frame and rotor measure 25mm thick and weigh 142 grams each, fitting standard mounting points.
Each fan connects via a standard 4-pin PWM header for motherboard speed control. The package contains three identical fans; no RGB lighting is included.
