Pump Reservoir Combo ek water blocks EK-Quantum Kinetic3 FLT D5 PWM 120mm D-RGB

The Pump Reservoir Combo EK-Quantum Kinetic3 FLT D5 PWM 120mm D-RGB is a compact integrated pump-and-reservoir unit from ek water blocks designed for custom liquid cooling loops in desktop PCs. It pairs a D5 PWM pump with a 120 mm form-factor cylindrical reservoir and includes addressable D-RGB illumination. The unit centralizes fluid circulation and reservoir capacity into a single module intended to simplify plumbing and reduce the number of separate components in a loop while allowing pump speed control via PWM and lighting customization through D-RGB headers.

Advantages

This combo integrates a proven D5 PWM pump and a 120 mm reservoir into one assembly, reducing the number of fittings and mounting points required. PWM control enables dynamic pump speed adjustment for balancing flow and noise. The addressable D-RGB lighting provides customizable visual feedback and aesthetic integration with other D-RGB components. The compact 120 mm form-factor reservoir conserves space inside many modern PC cases while maintaining sufficient fluid capacity for typical custom loops.

Suitable for

• Custom liquid cooling loops in high-performance desktop PCs
• Builds where internal space is limited and a compact pump-reservoir solution is required
• Systems that require PWM-controlled pump speed for thermal/noise balancing
• PC builds seeking addressable D-RGB lighting synchronization with other components

Key specifications

• Integrated D5 PWM pump paired with a 120 mm form-factor reservoir
• Addressable D-RGB illumination compatible with standard D-RGB headers
• Designed for use in custom PC liquid cooling loops
• Compact combined unit to reduce separate mounting and plumbing needs

How to use

Mount the EK-Quantum Kinetic3 FLT D5 PWM 120mm D-RGB in a suitable location inside the chassis that accommodates a 120 mm reservoir form factor and provides access to PWM and D-RGB headers. Connect the pump to a PWM-capable fan or pump header on the motherboard for speed control and attach the D-RGB cable to an addressable RGB header or controller for lighting. Integrate inlet and outlet tubing into the custom loop using appropriate fittings and ensure the loop is filled, bled, and leak-tested according to standard liquid-cooling procedures before powering the system.

Recommendations

Use compatible fittings and tubing sized for the unit’s ports, follow manufacturer guidance for mounting orientation and leak testing, and connect the pump to a PWM header to enable automatic speed regulation. Synchronize the D-RGB connection with the system controller to manage lighting effects. Regularly inspect the system for sediment or discoloration and perform routine maintenance as part of your loop care schedule.
