## Summary description

EK-Quantum Kinetic3 FLT D5 PWM 140mm D-RGB is a combined pump and reservoir unit from ek water blocks designed for custom PC liquid cooling loops. It pairs a D5 PWM pump with a 140 mm cylindrical reservoir and integrated D-RGB lighting. The unit supports PWM pump speed control for quiet operation and precise flow management, simplifies loop filling and monitoring, and is intended for desktop gaming and workstation systems requiring reliable coolant circulation and an aesthetic illuminated reservoir.

## Long description

EK-Quantum Kinetic3 FLT D5 PWM 140mm D-RGB is a combined pump-reservoir unit designed for custom PC liquid cooling loops. It integrates a proven D5 PWM pump with a 140 mm cylindrical reservoir and addressable D-RGB illumination, delivering continuous coolant circulation and visual feedback in a compact footprint. The unit supports PWM control for pump speed management, simplified filling and air-bleed features, and mounting options suitable for standard desktop gaming and workstation chassis layouts.
Advantages
The integrated design reduces the number of separate components and plumbing connections, lowering potential leak points and simplifying loop assembly. PWM speed control enables quiet operation at low loads and higher flow when required, while the transparent cylindrical reservoir makes coolant level and air bubble inspection straightforward. Addressable D-RGB lighting adds customizable visual indication without additional controllers if the motherboard supports standard D-RGB headers.
Suitable for
 Custom liquid-cooled gaming PCs where compact pump-reservoir integration is preferred
 Workstation systems requiring reliable coolant circulation and easy monitoring
 Builds with addressable RGB support for synchronized lighting effects
 Environments where PWM pump speed control is needed for noise or flow optimization
Key specifications
 Pump type: D5 PWM centrifugal pump integrated
 Reservoir form factor: cylindrical, 140 mm length
 Lighting: addressable D-RGB integrated along reservoir
 Control: PWM input for pump speed regulation
 Materials: transparent reservoir section with rigid mounting base
 Fittings: standard G1/4-compatible ports for inlet/outlet and filling
How to use
Install the unit according to the chassis and bracket compatibility, orienting the reservoir for visible level inspection and ensuring secure mounting. Connect the inlet and outlet ports to the rest of the loop with compatible G1/4 fittings and tubing. Attach the PWM cable to a motherboard pump or fan header capable of PWM control and connect the D-RGB cable to an addressable RGB header for lighting control. Fill the loop with the chosen coolant, perform air-bleeding procedures by running the pump at low speed and gently tilting or tapping the reservoir to release trapped air, and verify there are no leaks before regular operation.
Usage recommendations
Use coolant compatible with PC liquid-cooling materials and follow manufacturer's maintenance intervals: periodically inspect coolant level, check for discoloration, and replace coolant or clean the loop if performance or appearance declines. For optimal noise and flow balance, configure PWM profiles in the system BIOS or control software and ensure the pump receives a stable 12 V supply through the recommended header.
