Alphacool Core DDCzero Flat Reservoir 90 with Pump (14567)

The Alphacool Core DDCzero Flat Reservoir 90 with Pump is a compact flat coolant reservoir with the DDCzero PWM pump integrated and five G1/4 ports. It is the 90 model of the series, and the included bracket mounts it directly to any standard 120mm fan or radiator location. The larger size is the Flat Reservoir 140 with pump.

Properties

• Pump: DDCzero PWM, 3,000 to 4,800 RPM
• Ports: 5x G1/4
• Maximum flow rate: 220 L/h
• Maximum head pressure: 1.4 meters
• Lighting: 5V digital aRGB
• Material: acetal base, acrylic top

Reservoir and pump in one

The reservoir combines its tank with the powerful DDCzero pump, creating an all-in-one solution for custom liquid cooling systems where space is at a premium. Its ultra-compact, flat design makes it an excellent choice for small form factor PCs and other space-constrained builds. It keeps the performance and flexibility expected from the Core series while maintaining that size.

Base, top and ports

The reservoir features a durable acetal base paired with a crystal-clear acrylic top, providing both long-term reliability and a clear view of your coolant. Unlike traditional reservoir designs, all of the G1/4 threads are integrated directly into the base, for increased strength and durability. The ports provide flexible options for inlet, outlet, fill and drain configurations, making loop planning and configuration simple regardless of your system layout.

Lighting

Integrated digital aRGB lighting evenly illuminates the reservoir, showcasing coolant colors while complementing the clean styling of the Core lineup. It connects to any compatible 5V addressable RGB motherboard header. An optional Alphacool aRGB controller does the same job, for seamless synchronization with the rest of your system.

Pump

At the heart of the reservoir is the PWM-controlled pump, delivering up to the flow and head pressure listed above. PWM control allows the pump speed to be adjusted from one end of its adjustable operating range to the other. That gives the ideal balance between cooling performance and quiet operation. Its ceramic shaft and durable construction are designed for reliable long-term use in gaming systems, workstations and compact custom loops.

Mounting

To simplify installation, the package includes the Core Universal Mounting Kit with its mounting hardware, which lets the reservoir mount on a fan or radiator position. The bracket supports both standard (straight) and 90° rotated orientations, providing additional flexibility for tubing runs and component placement.

What the loop needs

A loop uses two of the ports, one in and one out, so the reservoir takes two G1/4 fittings. The other three take the three plugs in the box, and the plug tool sets them. The pump runs from a 4-Pin PWM cable. Alphacool's data for this kit gives 3,000 to 4,800 RPM, while the box list names the pump as the Core DDCzero 3300-4800rpm PWM Pump, which we also stock on its own. Alphacool's manual shows the pump installation and the inlet and outlet configuration for the Flat Reservoir 90, with the dimensions in millimeter (mm).
