Purpose-built high-pressure 120mm fan

The be quiet! BL094 Silent Wings 4 is a 120mm PWM case fan designed for high static pressure on radiators and dense heat sinks. It delivers 76 to 130 CFM airflow at 2500 to 2999 RPM while keeping noise between 30 and 35 dBA. The fluid-dynamic bearing and 6-pole motor target long life and low vibration.

Push-pin or screw mounting with PWM control

Anti-vibration push pins allow quick tool-free installation in standard 120mm case mounts. A screwed installation option is also provided for radiators or situations needing extra security. The 4-pin PWM connector lets the motherboard regulate speed automatically; no separate controller is included or required.

Verify 120mm mounting points and 4-pin header

Confirm your chassis or radiator has 120mm mounting holes with 25mm clearance for the frame thickness. Ensure the motherboard or fan hub offers a 4-pin PWM header for speed control. The all-black 120mm frame fits standard layouts, but physical space around the fan should be checked before ordering.

Vragen over dit artikel

How can I confirm the fan is running at the correct 2500-2999 RPM after installation?

Connect the 4-pin PWM header to the motherboard and monitor the RPM reading in BIOS or fan-control software; the value should sit within the 2500-2999 range at full speed.

What mounting hardware is included and do I need to buy screws separately?

The box contains the 120mm fan, anti-vibration push pins for tool-free mounting, and standard screws for the alternative screwed installation — no extra hardware is required.

Which version should I choose if I need maximum static pressure for a radiator?

The high-speed PWM model delivered here is the one optimised for radiators and heatsinks, offering 76-130 CFM airflow at 30-35 dBA with a 300,000-hour rated lifespan.
