Who it fits

Key specs explained

Dual Pump Configuration

This feature lets you mount two pumps in series. You gain higher pressure and flow for long loops or multiple radiators. It suits builders who need maximum performance. Compare this to single pump tops if you have a short loop with minimal resistance. This setup ensures your coolant moves efficiently through complex tubing paths.

98 mm height including feet

This dimension defines the total vertical space the unit occupies. You need to check your case clearance to ensure it fits without blocking other components. A lower profile helps in compact builds. Compare this height against your available space above the radiator or reservoir. Accurate measurement prevents installation conflicts.

3x 1/4" inlet ports

These ports allow you to connect three separate tubes for input. You can feed water from different sources or split flow for specific components. This offers flexibility in loop design. Compare this capacity to tops with fewer ports if you plan a complex routing scheme. It supports intricate custom loop layouts.

3x 1/4" outlet ports

These ports provide three connection points for outgoing coolant. You can direct flow to various parts of your system efficiently. This supports balanced distribution in large loops. Compare this to units with limited outlets if you have many components. It ensures your loop remains organized and functional.

Brass Construction

Brass offers durability and a premium aesthetic for your build. It resists corrosion and maintains structural integrity over time. This material suits long-term custom loop enthusiasts. Compare brass to plastic tops if you prioritize longevity and visual appeal. It provides a solid foundation for high-performance water cooling.

Brass Build and Physical Layout

According to the listing, this top is constructed from high-quality brass. The feet are made of aluminum. This material choice suggests a focus on durability and thermal mass rather than lightweight aesthetics. The finish is deep black, which provides a sleek, uniform look for dark-themed builds. The design includes patented ultra-flat screw plugs. These contribute to clean, clear lines and a stylish appearance without protruding hardware. You get a premium visual result that matches high-end components.

The dimensions are 154 x 78 x 40 mm, with a height of 98 mm including feet. It weighs 3.12 kilograms. This substantial weight helps stabilize the pump assembly, reducing movement within the case. The layout offers three 1/4" inlet ports and three 1/4" outlet ports. This provides comprehensive connectivity for your tubing runs. You can connect multiple radiators or components without needing additional manifolds.

Mounting flexibility is a key feature. You can install the unit vertically, horizontally, or at 45 or 90-degree angles. The included feet allow for versatile placement in various case configurations. Vibration dampers are integrated to significantly reduce pump noise. This ensures quiet operation while maintaining optimal performance. The design supports both DC-LT and Laing D5 pumps, making it a practical upgrade for existing loops.

Setup and Everyday Use Guide

Installing this Alphacool Eisdecke Dual D5 Brass Pump Top requires careful planning due to its dual pump design. You must connect two pumps in series to utilize the unit fully. The listing confirms compatibility with Laing D5 pumps. You can also use it with Alphacool DC-LT, Laing DDC, or Eispumpe VPP755 units. This flexibility allows you to choose the pump that best fits your loop’s pressure needs. The top includes three 1/4-inch inlet ports and three 1/4-inch outlet ports. You can route tubing in multiple directions. This layout simplifies connections in tight cases or complex builds. The included feet allow vertical, horizontal, or angled mounting. You can position the assembly at 45 or 90 degree angles. This versatility helps you fit the pump top into various case configurations without modifying the case itself. The unit weighs 3.12 kilograms. Its substantial weight suggests stability during operation. The brass construction provides thermal mass, which may help dissipate heat from the pump motor. Vibration dampers are included to reduce noise. You will experience quieter operation compared to direct mounting. The patented ultra-flat screw plugs contribute to a clean appearance. Daily use involves monitoring flow rates and temperatures. The dual pump setup increases pressure, which is ideal for long loops or multiple radiators. Ensure your tubing matches the 1/4-inch ports. The black finish resists fingerprints. Regular maintenance involves checking for leaks at the threaded connections. The design prioritizes performance and durability over minimalism.

Before You Buy This Dual Pump Top

You need to verify that your reservoir and tubing fit the included ports. The listing specifies nine 1/4" connections for inlet and outlet. You must ensure your case has enough space for the dual pump setup. The unit weighs 3.12 kilograms. This mass helps with stability but requires sturdy mounting. You should also check if your existing pump supports the DC-LT, Laing DDC, or Eispumpe VPP755 standards mentioned. Regular maintenance involves checking for leaks around the patented ultra-flat screw plugs. Vibration dampers help reduce noise, but you should inspect them periodically. This component suits builders who prioritize flow pressure over simplicity. It does not fit single-pump loops. You should compare this against single pump tops if your loop is short. It pairs well with high-end radiators. Avoid this if you lack space or need a simpler setup. The brass construction offers durability but adds weight. Plan your tubing routes carefully to avoid kinks near the multiple ports.

Check before you buy

• Verify your pump model matches D5 or listed compatible types.
• Check case space for the 154 x 78 x 40 mm size.
• Ensure you have enough 1/4" tubing for nine connections.
• Confirm your reservoir supports dual pump series configuration.
