## Long description

Watercool MO-RA IV Tank 200 D5 expansion tank-pump combination ARGB acrylic is a compact reservoir and pump mounting unit designed for custom PC liquid-cooling loops. Made from clear acrylic, it provides a 200 mm form-factor tank that shows coolant level and flow while integrating a compatible D5 pump mounting interface and addressable RGB illumination. The product simplifies installation of reservoir and pump, keeps coolant visible for monitoring, and adds controllable ARGB lighting to a cooling loop.
Advantages
The acrylic construction offers clear visibility of coolant and allows easy monitoring of fill level and air bubbles. Integration of a dedicated D5 pump mount reduces the need for separate brackets and shortens assembly time. Built-in addressable RGB lighting provides customizable system illumination that can be synchronized with motherboard ARGB headers. The 200 mm tank form factor balances capacity and space efficiency for a variety of PC cases and radiator configurations.
Suitable for
Custom PC liquid-cooling loops requiring a compact reservoir and D5 pump integration
Systems where visible coolant level and leak monitoring are desired
Builds that use ARGB lighting for coordinated system aesthetics
Setups that need a mid-size reservoir compatible with single D5 pump solutions
Key specifications
Material: clear acrylic reservoir body suitable for visible coolant monitoring
Tank length/form factor: 200 mm capacity-oriented design
Pump compatibility: mounting interface for standard D5-series pumps
Lighting: integrated addressable RGB illumination compatible with ARGB controllers/headers
Connection points: threaded ports for coolant inlet/outlet and fill/drain operations (standard fittings required separately)
Mounting: bracket/interface for secure installation inside PC chassis or on radiators depending on case layout
How to use
Mount the MO-RA IV Tank 200 to a suitable location within the chassis or on a compatible radiator mount using the supplied mounting points and brackets. Install a D5 pump onto the dedicated pump mount following the pump manufacturer’s orientation and torque recommendations. Connect standard liquid-cooling fittings to the inlet and outlet ports and integrate the reservoir into the loop with tubing routed to the radiator, CPU/GPU blocks and pump. Connect the ARGB lighting header to a compatible controller or motherboard ARGB header and configure lighting via the system software or controller.
Usage recommendations
Use coolant compatible with acrylic materials and avoid solvents that can cause stress cracking. Tighten fittings to manufacturer torque specifications to prevent leaks and perform an initial leak test before powering other components. Periodically inspect coolant level and clarity; refill or replace coolant as recommended by the coolant manufacturer. When configuring ARGB lighting, ensure voltage and pinout compatibility with your controller or motherboard header.
