Product information

Description

Watercool MO-RA IV Passive Control PWM/aRGB is a multi-fan passive radiator intended for custom liquid cooling loops in desktop PCs. The unit provides a large surface area for heat dissipation, a flexible fan layout that supports multiple fan configurations, and integrated addressable RGB lighting compatibility. It is designed to be mounted in external or internal radiator bays where space and airflow can be optimized for efficient passive or active cooling.

Advantages

The MO-RA IV Passive Control integrates PWM fan control compatibility, enabling synchronized speed management across connected fans for improved thermal performance and reduced noise. Addressable RGB support allows individual LED control for consistent lighting effects with compatible controllers or motherboard software. Its multi-fan design and expanded fin area increase heat transfer capacity compared with single-fan radiators, while the modular mounting points accommodate different fan sizes and arrangements.

Suitable for

  • Custom water-cooling loops for high-performance desktops
  • Silent or low-noise PC builds where large passive radiators are preferred
  • Systems requiring flexible fan layouts and RGB lighting synchronization
  • External radiator installations in test benches or compact cases with space for larger cooling assemblies

Key specifications

  • Form factor: multi-fan passive radiator suitable for custom liquid cooling loops
  • Fan compatibility: supports multiple fan mounting positions and sizes for various airflow configurations
  • Control interface: compatible with PWM fan speed control for coordinated fan operation
  • Lighting: addressable RGB (aRGB) support for individually addressable LED control and synchronization
  • Thermal design: expanded fin and tube surface area optimized for heat dissipation in passive or active setups
  • Mounting: modular mounting points to accommodate different installation orientations and bracket systems

How to use

Install the MO-RA IV Passive Control into your custom loop following the radiator mounting guidelines for your case or external mount. Connect fans to a PWM-capable header or a PWM fan hub to enable coordinated speed control. Connect the aRGB cable to a compatible aRGB controller or motherboard header to enable lighting synchronization. Ensure proper coolant flow through the loop and verify secure fittings and leak-free connections before powering the system. Position fans and configure PWM curves to balance noise levels and cooling performance according to your system's heat load.

Usage recommendations

For optimal results, use PWM-capable fans and a compatible aRGB controller or motherboard header. Regularly inspect fins and fan blades for dust buildup and perform periodic maintenance on the loop to maintain thermal efficiency. When planning installation, allow adequate clearance for airflow and hose routing to maximize the radiator's heat dissipation capabilities.
