Fractal Design Dynamic 3 140mm RGB Black Fan - ARGB PWM
The Fractal Design Dynamic 3 140mm RGB Black Fan is an ARGB PWM case fan designed for builders who want balanced cooling performance with customizable lighting and quiet operation. It combines strong airflow with a swept blade design that reduces noise, making it suitable for system builds where both thermal management and acoustics matter.
Why this product
Strong airflow with quiet operation
Delivers 76.3 CFM of airflow with a maximum noise level of 30.8 dB(A), thanks to a swept blade design that prioritizes acoustic performance without sacrificing cooling capacity.
Wide PWM speed control
Ranges from 350 to 1800 RPM, giving you fine-tuned control over cooling intensity and noise output across the full operating range.
ARGB Gen 2 with 8 LEDs
Integrated lighting with customizable color effects and dynamic animations, daisy-chainable with other compatible RGB devices for coordinated system lighting.
Rifle bearing for long-term stability
Engineered for smooth, consistent rotation over time with an MTTF rating exceeding 90,000 hours.
Daisy-chainable connector design
Integrated cables with daisy-chain capability simplify multi-fan setups and reduce cable clutter inside your case.
- Size140 x 140 x 25 mm
- Maximum speed1800 RPM
- Maximum airflow76.3 CFM / 129.6 m³/h
- Noise level30.8 dB(A)
- LightingARGB Gen 2 (8 LEDs)
- Bearing typeRifle
- Warranty2 years
- SKUFRA-6775
- EAN7340172711841
- Fits standard 140mm mounting locations with 125 x 125 mm screw hole pattern.
- 4-pin PWM connector for automatic motherboard-based speed control; 3-pin RGB connector for ARGB lighting (5V).
- Operates on 12V input with minimum startup voltage of 7V, compatible with most PC power supplies and fan controllers.
- RGB functionality requires a 5V ARGB header on the motherboard or an external RGB controller; PWM cooling function works independently if RGB is not connected.
Best for
- Balanced builds prioritizing both cooling and noise reduction
- RGB-lit systems where coordinated lighting across multiple fans is desired
- Cases where cable management and daisy-chaining multiple fans matter
- Users who want programmable speed control through PWM without fixed fan curves
Trade-offs
- Extreme cooling setups requiring maximum static pressure; maximum pressure is 2.61 mm H2O, suitable for standard radiators but not high-restriction components.
- Non-RGB motherboards without external RGB controller — lighting features cannot be used without a 5V ARGB header.
- Budget builds avoiding RGB where a simpler PWM-only fan would save cost without adding lighting capability.
