## Summary description

Watercool MO-RA IV Tank 600 ARGB module is an external reservoir component designed for the MO-RA IV 600 radiator. It provides a refill and expansion tank with integrated ARGB lighting compatibility for custom liquid-cooling loops. Intended for PC water-cooling builds using the MO-RA IV 600, it facilitates fluid management, refilling and visual lighting integration without altering core radiator performance.

## Long description

The Watercool MO-RA IV Tank 600 ARGB module is an external reservoir specifically designed to pair with the MO-RA IV 600 radiator. It serves as a refill and expansion tank for custom PC liquid-cooling loops, allowing controlled fluid management and convenient top-up access while integrating addressable RGB lighting for coordinated system illumination. The module mounts externally to the MO-RA IV 600 and works alongside the radiator without changing its thermal characteristics.
Advantages
This tank provides a dedicated refill point and expansion volume that simplifies maintenance of a liquid-cooling loop and reduces the need to reach into confined case spaces. Integrated ARGB compatibility enables synchronized lighting with other addressable RGB components for a cohesive visual appearance. The modular nature of the unit preserves the original radiator performance while adding reservoir functionality and improved ease of use for filling and bleeding the loop.
Suitable for
 Custom PC water-cooling systems using the MO-RA IV 600 radiator
 Users who want an external refill/expansion tank with ARGB lighting
 Maintenance and loop-filling tasks where easy access to a fill port is preferred
Key specifications
 Form factor: external reservoir module sized to match the MO-RA IV 600
 Function: refill and expansion tank for liquid-cooling loops
 Lighting: addressable RGB (ARGB) compatible for synchronized illumination
 Mounting: designed to attach to the MO-RA IV 600 radiator assembly
 Material considerations: corrosion-resistant construction suitable for coolant use
How to use
Mount the tank to the MO-RA IV 600 radiator following the manufacturer’s mounting points and instructions, ensuring a secure mechanical fit. Connect the inlet and outlet ports to the loop with appropriate tubing and fittings, and integrate the ARGB header to your motherboard or controller for lighting control. Fill the loop through the tank’s fill port, purge trapped air by running the pump at low speed and topping up until the system is free of air pockets, then verify all fittings for leaks before regular operation.
Usage recommendations
Use coolant formulated for PC water-cooling and follow manufacturer guidance on coolant maintenance intervals. When installing or removing the module, drain the loop or isolate the section to avoid spills. Match tubing and fittings to the tank’s port sizes and ensure ARGB connections use compatible headers or adapters for reliable lighting control.
