Pump & reservoir EK Water Blocks TBE 200 D5 PWM D-RGB Acetal Steel Black

The EK Water Blocks TBE 200 D5 PWM D-RGB Acetal Steel Black is a pump and reservoir combo engineered for closed-loop and custom liquid cooling systems. It combines a genuine D5 PWM pump with a 60 mm diameter acrylic reservoir, CNC-machined acetal top and bottom, and a robust steel mounting assembly finished in black. The unit integrates addressable D-RGB lighting compatible with common motherboard sync standards and offers multiple G1/4" ports for flexible inlet, outlet, filling and draining arrangements. Dimensions are 78 mm (W) x 91.1 mm (D) x 197.9 mm (H), making it suitable for a variety of PC layouts.

Advantages

The combo unit provides reliable pump performance and low-noise operation thanks to the D5 PWM motor and a rubber vibration-damping mount that decouples the pump from the mounting clip. Six G1/4" ports (three on the top, three on the bottom) allow versatile tube routing, filling and draining options, while a pre-installed nickel-plated brass internal tube on the top port reduces splashing and air intake. The durable construction uses high-quality acrylic for the reservoir tube and CNC-machined POM acetal for critical components, sealed with an EPDM o-ring for leak resistance. Integrated addressable D-RGB lighting offers synchronized illumination with motherboard controllers.

Suitable for

• Custom PC liquid cooling loops requiring a dedicated D5 pump-reservoir combo
• High-performance desktops where quiet pump operation and vibration control are needed
• Systems that benefit from multiple inlet/outlet options for complex tube routing
• Builds that use motherboard D‑RGB synchronization for coordinated lighting

How to use

Install the pump-reservoir unit in a suitable location inside the case using the supplied steel mounting bracket and ensure the rubber dampers are positioned to decouple vibrations. Connect tubing to the appropriate G1/4" ports according to your loop layout, using the bottom side ports for typical inlet/outlet and the top ports for filling or additional accessories. Align the 3‑pin D‑RGB connector arrow with the +5V marking on the motherboard header for lighting control. Fill the loop with an appropriate coolant, bleed air from the system thoroughly, then power the pump at low speed to verify leak-free operation before normal use.

Recommendations

Use coolant fluids approved for PC liquid cooling and avoid aggressive chemicals or unapproved additives. When mounting the unit, allow for clear tubing paths and access to the top filling port to simplify maintenance. Periodically inspect fittings and seals for tightness and replace the EPDM o-ring if signs of wear appear. For optimal noise and lifespan, configure PWM control to limit sustained maximum pump speeds unless higher flow is required by the loop.
