6. Alphacool PUZ Core Square pump holder VPP/D5 aluminium black
This bracket allows VPP/D5 pumps to be mounted on the Core Series distro plate. Compatibility: Core distro plate. Technical data: Dimensions (L x W x H) 75.30 x 75.30 x 12.35 mm. Material: Aluminum. Weight: 85 g. Colour: Black.

7. Aqua Computer Ultitop pump adapter for D5 pumps
During the development of the Ultitop D5, attention was paid to optimal flow behavior, resulting in extremely quiet and smooth operation. A mounting ring made of anodized aluminum and a matching seal are included for mounting a D5 pump (not included). A mounting bracket with silicone decouplers specially developed for the Ultitop effectively prevents the transmission of vibrations to the computer case. Stainless steel plates with M3 threads are inserted into the silicone decouplers for mounting. The mount can be detached from the Ultitop by loosening a single screw for easy access to the pump.

8. Alphacool Vpp655 Pwm
Alphacool's attachment for the Laing D5 is now part of the Eisdecken series and has received an update.
This attachment has been a benchmark for years, with small improvements made repeatedly. The second major update differs both visually and technically in several details.
The principle: there is space for the Laing D5 or VPP655 on the underside, with inlets and outlets at the front and top.
For even more flexibility, the Eisdecke features three inlets and two outlets. Another feature is the new mounting bracket, which provides a stable base for the entire unit and enhances the overall aesthetic. Optionally, installation in a 3.5" bay is also possible.
The attachment can be transformed into a complete expansion tank with the help of the optional expansion tank attachment, which has also been revised.

10. EKWB EK-Loop VTX PWM motor
The EK Water Blocks EK-Loop VTX PWM Motor is a high-performance water pump specifically designed for custom loop water cooling systems. It allows for precise control of the pump speed via PWM (Pulse Width Modulation), enabling adjustments to meet the specific requirements of the cooling loop. This pump is compatible with all DDC holders and offers an impressive combination of pressure build-up and flow rate, making it ideal for compact cases. With a maximum pressure of up to 5.3 meters and a flow rate of 1100 L/h, it can efficiently support even demanding cooling configurations. The use of an optional convection heat sink is possible but not mandatory, providing additional flexibility in installation. The pump is approved for operation with water and water/glycol mixtures and can be operated in a temperature range of up to 60 degrees Celsius.
- PWM-controlled speed regulation for optimal adjustment
- Compatible with all DDC holders for versatile applications
- Maximum pressure of 5.3 meters for effective cooling
- Flow rate of 1100 L/h for sufficient coolant flow
- Robust construction with high-quality materials such as copper coils and stainless steel shaft.
