Description
The darkFlash DM20 120mm ARGB PWM fan represents a fusion of advanced thermal engineering and premium aesthetics. Designed for high-visibility PC builds, it features a signature infinity mirror effect that creates an illusion of endless depth, complemented by a sleek linear frame design. Operating at speeds between 800 and 1600 RPM, the DM20 delivers a robust 56 CFM of airflow and 1.8 mm H2O static pressure, ensuring that internal components remain cool under heavy workloads while maintaining a maximum noise level of 32.5 dBA.
This product is for:
- PC Enthusiasts looking to build a showcase system with synchronized ARGB lighting and infinity mirror accents.
- Gamers requiring reliable PWM-controlled cooling to manage thermal loads during intensive gameplay.
- Custom Loop Builders who need high static pressure fans for radiator configurations.
- Aesthetic-focused users who prefer the clean look of reverse blade fans for intake positions in panoramic cases.
- System Integrators seeking a durable cooling solution with a 40,000-hour rated hydraulic bearing lifespan.

In practical application, the darkFlash DM20 excels in both air-cooled and liquid-cooled environments. The specialized blade material is engineered to diffuse ARGB light uniformly, eliminating harsh hotspots and creating a smooth glow across the fan surface. The PWM functionality allows for precise control via the motherboard, enabling the fan to whisper at idle and provide significant cooling power when temperatures rise. The inclusion of the DM20RB reverse blade model is particularly beneficial for bottom or side intake mounts, allowing users to display the infinity mirror hub rather than the plastic frame brackets.
Compared to standard 120mm ARGB fans, the DM20 offers a more sophisticated visual profile through its dual-zone infinity mirror implementation. While many entry-level fans utilize sleeve bearings, the DM20's hydraulic bearing provides superior longevity and quieter operation over time. Furthermore, the availability of a dedicated reverse-flow version sets it apart from competitors that force users to choose between optimal airflow direction and the fan's best-looking side in modern 'aquarium' style chassis.
Q&A:
- What is the difference between the DM20BK and DM20RB models? The DM20BK is a standard forward-flow fan typically used for exhaust, while the DM20RB features reverse blades designed for intake applications to keep the aesthetic side visible.
- Does the darkFlash DM20 support motherboard lighting synchronization? Yes, the ARGB lighting is compatible with standard 3-pin headers for synchronization with major motherboard RGB software.
- How loud is the DM20 fan during full load? At its maximum speed of 1600 RPM, the fan produces a noise level of approximately 32.5 dBA, which is comparable to a quiet library environment.
- Can these fans be used on liquid cooling radiators? Yes, with a static pressure of 1.8 mm H2O, the DM20 is capable of pushing air through the dense fins of most standard PC radiators.
- What is the expected lifespan of the hydraulic bearing? The hydraulic bearing in the DM20 is rated for 40,000 hours of operation, providing long-term reliability for daily use.
