The Alphacool Core DDCzero Flat Reservoir 90 combines a compact coolant reservoir with the powerful DDCzero PWM 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 while maintaining the performance and flexibility expected from the Alphacool Core series.

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 G1/4" threads are integrated directly into the acetal base for increased strength and durability. Five G1/4" ports provide flexible options for inlet, outlet, fill, and drain configurations, making loop planning simple regardless of your system layout.

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

At the heart of the reservoir is the Alphacool DDCzero PWM pump, delivering up to 220 L/h of flow with a maximum head pressure of 1.4 meters. PWM control allows the pump speed to be adjusted from 3,000 to 4,800 RPM, providing 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.

To simplify installation, the included Alphacool Core Universal Mounting Kit allows the reservoir to mount directly to any standard 120mm fan or radiator location. The bracket supports both standard and 90° rotated orientations, providing additional flexibility for tubing runs and component placement.
