lian li DAN Cases A3‑mATX case (black) with 3× UNI FAN SL‑INF 120 ARGB Reverse Blade + 1× 120mm PWM fan (incl. controller)

The lian li DAN Cases A3‑mATX case (black) bundle is a compact micro‑ATX PC kit that pairs a minimalist, space‑efficient chassis with three UNI FAN SL‑INF 120 ARGB Reverse Blade fans and one 120mm PWM fan. The package includes an ARGB‑capable controller that manages lighting effects and synchronisation while PWM control enables fan speed regulation for a balance between cooling performance and acoustic output. The case is designed for small‑form‑factor builds where internal layout and airflow are tailored to mATX motherboards and compact power supplies.

Advantages

The A3‑mATX chassis provides a compact footprint with practical internal space for micro‑ATX components and efficient cable routing. The three UNI FAN SL‑INF 120 ARGB Reverse Blade fans are optimised for directed airflow and visual customisation through ARGB lighting, while the included 120mm PWM fan adds an additional, speed‑controllable airflow source. The supplied controller integrates ARGB lighting control and fan headers to simplify installation and configuration without requiring separate accessories.

Suitable for

• Compact micro‑ATX gaming or productivity builds
• Home or office systems where desk space is limited
• Users who want configurable ARGB lighting in a small chassis
• Systems requiring a balance of airflow and low noise via PWM control

When it may not be suitable

This bundle is not intended for full‑tower or ATX‑sized motherboards and may not accommodate large air coolers or multiple large graphics cards due to the compact internal dimensions. Users planning extreme overclocking, multi‑GPU configurations, or extensive liquid‑cooling radiators should consider larger chassis options with greater clearance and mounting points.

Key specifications

• Form factor: micro‑ATX compatible chassis
• Included fans: 3 × 120mm UNI FAN SL‑INF ARGB Reverse Blade; 1 × 120mm PWM fan
• Lighting: ARGB support with included controller for lighting effects and synchronisation
• Fan control: PWM support for speed regulation
• Cooling focus: airflow‑oriented reverse‑blade fan design
• Colour: black exterior finish

How to use

Install the micro‑ATX motherboard and compact power supply into the A3‑mATX chassis following the case manual. Mount the provided fans to the designated fan locations and connect the fan power and ARGB cables to the included controller. Use the controller to assign lighting profiles and connect the PWM fan header to the motherboard or controller for automatic speed management based on system temperatures. Route cables neatly to maintain unobstructed airflow and verify fan orientation for intended intake and exhaust flow before first power‑on.

What to consider before purchase

• Ensure motherboard form factor is micro‑ATX or smaller
• Check CPU cooler and GPU clearance against case dimensions
• Confirm power supply length and connector compatibility for compact builds
• Verify desired ARGB synchronisation compatibility with existing components

Usage recommendations

For balanced thermal performance and low noise, configure the three UNI FAN SL‑INF ARGB fans as front intake and use the 120mm PWM fan as rear exhaust. Enable PWM control via the motherboard or the included controller and use ARGB profiles that do not impede temperature monitoring. Periodically clean fan blades and dust filters to maintain airflow efficiency.
