Compact 120 ml DDC Reservoir

The Phanteks Glacier EZ-Fit 120RES-DDC body is a white acrylic reservoir designed to mount directly to a DDC pump. Integrated 16 mm EZ-Fit fittings accept hard or soft tubing for a quick custom-loop build. A top fill port and addressable D-RGB lighting behind an aluminium cover complete the unit. Dimensions are 45 x 120 x 124 mm with a 120 ml capacity. Pump is not included.

Builders using DDC pumps

This reservoir suits builders assembling a custom water-cooling loop around a standard DDC pump who want pre-installed fittings and flexible port placement. It is not for loops built around larger D5 pumps or for anyone needing a reservoir with greater fluid volume than 120 ml. The 120 x 120 mm mounting pattern fits standard fan locations but will not align with proprietary brackets.

120 ml capacity

The 120 ml volume determines how much coolant the loop holds and how often the fill port must be accessed. Verify that this capacity meets your thermal mass and maintenance preferences before purchase. The integrated 16 mm fittings fix the tubing size, so ensure your loop uses matching 16 mm hard or soft tube.

Questions about this item

How much heat does the 120ml acrylic body add to the loop when the DDC pump runs continuously?

The reservoir itself is passive; all heat comes from the DDC pump you install, so loop temperature depends on that pump's waste heat and your radiator capacity.

Which DDC pump and tubing must I already own for the integrated 16mm EZ-Fit fittings to work?

You need a standard DDC-format pump top and either 16mm OD hard tube or 16mm ID soft tube; the fittings accept both without adapters.

Will the 45 x 120 x 124 mm footprint and 120mm fan mounting pattern let me keep my existing 120mm radiator fan in the same spot?

Yes, the reservoir mounts directly on any 120 x 120mm fan frame, so it can sit in front of or behind your current 120mm radiator fan without moving it.
