SilentiumPC ENDORFY Stratus 120 PWM ARGB fan 120 mm, Fluid Dynamic Bearing, 200–1400 RPM, black

The SilentiumPC ENDORFY Stratus 120 PWM ARGB is a 120 mm case fan designed to provide quiet and efficient airflow for desktop PCs. Equipped with a Fluid Dynamic Bearing (FDB) and PWM control, it operates in the 200–1400 RPM range and includes ARGB lighting for customizable illumination. The fan is intended for intake or exhaust configurations and fits standard 120 mm mounting points.

Advantages

The Stratus 120 PWM ARGB combines a low-noise FDB drivetrain with optimized rotor geometry to maintain smooth, silent operation even under prolonged load or when airflow is partially obstructed by dense dust filters. PWM control enables precise speed adjustment from 200 to 1400 RPM for a balance of cooling performance and acoustics, while ARGB lighting offers flexible visual customization compatible with common motherboard and controller standards.

Suitable for

• Case cooling for desktop PCs (intake or exhaust)
• Systems requiring low-noise operation, such as home offices or workstations
• Builds where customizable ARGB lighting is desired

When it may not be suitable

This 120 mm fan is not suitable for setups that require larger fans or radiators (e.g., 140 mm mounting points or large custom radiator arrays). If passive or completely fanless cooling is required, an active fan—even a quiet one—will not meet that need. Also, ARGB lighting requires a compatible controller or motherboard header to use full customization features.

Key specifications

• Fan diameter: 120 mm
• Bearing type: Fluid Dynamic Bearing (FDB)
• Speed control: PWM, adjustable 200–1400 RPM
• Colour: Black
• Lighting: Addressable RGB (ARGB), compatible with common controllers and motherboards
• Mounting: standard 120 mm case fan mounting

How to use

Install the Stratus 120 PWM ARGB into a 120 mm fan slot in your case using the supplied mounting hardware. Connect the PWM power cable to a compatible motherboard fan header for automatic speed control, and attach the ARGB cable to a compatible ARGB header or controller to manage lighting. Adjust fan speed via motherboard BIOS or software to balance cooling and noise according to system load.

What to consider before purchase

• Confirm your case has a 120 mm mounting location
• Verify your motherboard or controller has the required PWM fan header and ARGB header for full functionality
• Consider airflow needs—single 120 mm fans provide moderate airflow compared with larger or multiple-fan setups

Usage recommendations

For quiet daily use, set PWM control to keep idle speeds near the lower end of the 200–1400 RPM range and allow ramp-up under load. Use the ARGB header or compatible controller to synchronize lighting with other components.
