Radiator Watercool MO-RA IV 600 black — supports 120 mm fans

Watercool MO-RA IV 600 in black is an external slim-profile radiator engineered for liquid cooling systems. It supports multiple 120 mm fans across its large surface area to maximize heat dissipation from coolant loops. Designed for custom PC builds and high-performance cooling configurations, the MO-RA IV 600 provides extended radiator capacity to lower component temperatures while enabling quieter fan operation when paired with appropriate fans and pumps.

Advantages

The radiator offers a broad fin area and a multi-fan mounting layout that increases thermal transfer without requiring excessive fan speed. Its black finish delivers corrosion resistance and a neutral visual appearance for diverse system builds. Compatibility with standard 120 mm fan mounts and a spacious core volume allow flexible loop planning, easier routing of fittings, and improved overall thermal headroom for demanding components.

Suitable for

• Custom desktop water cooling loops for CPUs and GPUs
• High-performance workstations and overclocked systems
• External radiator setups where additional cooling capacity is required
• Low-noise cooling configurations using high-efficiency fans

Key specifications

• Fan compatibility: 120 mm fans (multiple mounting positions)
• Finish: black
• Design: external slim-profile radiator with large fin surface area
• Cooling capacity: optimized for expanded loop heat dissipation in custom systems
• Material characteristics: corrosion-resistant coating suitable for liquid cooling environments

How to use

Install the MO-RA IV 600 in an appropriate external location or on a dedicated mount, aligning the 120 mm fan holes with the radiator’s mounting pattern. Secure fans using the provided or recommended screws, and connect inlet and outlet ports to your loop using compatible fittings and tubing. Fill and bleed the loop according to your coolant and pump manufacturer's instructions, then perform a leak test at low pump speed before normal operation.

Recommendations

For best performance pair the radiator with high-efficiency 120 mm fans running at moderate RPM to balance airflow and acoustic levels. Use corrosion-inhibiting coolant and regular maintenance (periodic flushing and dust removal) to preserve heat transfer efficiency and prolong service life.
