Reservoir Aquatuning GmbH 1022162 Acetal Acrylic Black Transparent 76.5mm

The Alphacool Core reservoir (Reservoir Aquatuning GmbH 1022162, MPN 15393) combines an acrylic tube and acetal pump top and lid to deliver a compact reservoir for PC liquid cooling. The model features a transparent acrylic body with a black acetal pump top and integrated aRGB lighting. The reservoir is compatible with D5 and Alphacool VPP pumps and includes mounting accessories and installation hardware.

Advantages

The external thread on the acrylic tube improves mechanical stability and safety when attaching the lid and pump top. Integrated digitally addressable aRGB lighting (12 LEDs) is included, eliminating the need for a separate lighting ring. The combination of the Lighttower water effect and ring-mounted LEDs provides uniform illumination and visual water effects inside the acrylic tube. The reservoir ships with pump retaining ring, pump O‑ring, screws and multiple mounting frames for flexible installation.

Suitable for

• Custom PC liquid cooling loops using D5 or VPP pumps
• Enclosures with available 120 mm or 140 mm fan spaces
• Systems where visible reservoir lighting and water effects are desired

How to use

Install the acrylic tube, secure the pump top and lid using the external thread, and fit the pump (D5/VPP) with the supplied retaining ring and O‑ring. Choose one of the supplied mounting options: use the included stands to place the reservoir on the case bottom or attach the 120/140 mm mounting frames to available fan slots or radiator fan positions. Connect the aRGB JST 3‑pin cable to a compatible 5 V digital RGB header or controller. Fill the loop following standard filling and bleeding procedures, ensuring the riser tube height produces the desired Lighttower water effect.

Recommendations

Do not overfill beyond the top edge of the selected riser tube if you want to preserve the Lighttower fountain effect; filling above the riser tube will reduce the visible water motion. Use a 5 V digital RGB controller or motherboard header to manage the 12 LEDs. Verify pump compatibility and secure all fittings before powering the system.
