Custom liquid cooling builds just gained a new option for standard ATX cases. EK by LM TEK released the EK-Quantum Reflection³ Uni Distro Plate 300 D5 to simplify reservoir and pump integration. This release matters because it removes the need for custom mounting brackets in popular mid-tower chassis. Users can now install a high-performance cooling loop without modifying their case structure.
The new 300ml reservoir and pump combo fits standard 120mm fan mounts
The distribution plate serves as the central hub for the cooling loop. It combines a 300 milliliter reservoir with a Generation 3 D5 PWM pump. This configuration allows for significant coolant volume while maintaining a compact footprint. The unit is designed to fit directly into the standard 120 millimeter fan mounting holes found on most ATX motherboards.
Specifications
- Reservoir Volume: 300 ml
- Pump Type: Generation 3 D5 PWM
- Dimensions: 130 x 80.5 x 300 mm
- LED Lighting: 16 D-RGB LEDs
- Price: $359.99 USD
Technical specifications highlight the plate's integrated features and dimensions. The unit measures 130 by 80.5 by 300 millimeters with the pump attached. It includes an integrated EK Bypass Valve for easier fluid management. The pump delivers a maximum flow rate of 1500 liters per hour against a head pressure of 3.9 meters.
Visual customization is handled by a full-length addressable D-RGB LED strip. The strip contains 16 individual LEDs that run the length of the plate. All fluid connections use standard G1/4 inch ports for broad compatibility. The distribution plate includes the required fittings for connecting standard tubing sizes.
EK by LM TEK lists the EK-Quantum Reflection³ Uni Distro Plate 300 D5 at 359.99 USD. The company states the product is now available to order through the EK Shop. This global availability allows international builders to access the component immediately.
This product marks the first time the company has released a universal ATX distribution plate. Earlier models frequently required specific case compatibility or custom mounting solutions. The integrated bypass valve provides added convenience compared to earlier iterations. Builders seeking a clean install in standard ATX cases have a new verified option.
