Protium:
Protium is a set of components for creating pump and reservoir combinations which increases performance, mounting options, flow inlet/outlet options and will be a feature in your build. We set out to create the most minimalistic and compact components, but at the same time providing the most options and compatibility. Our components are refined in ways only possible due to our 15 years of experience in liquid cooling. Each component is carved from a solid block of material on a CNC mill. Creating our different finishes, frosted and polished acrylic is unique and takes a lot of effort to manufacture. Protium is designed for enthusiasts who want to enjoy building systems with the freedom to create something individual.

Protium Reservoir:
Protium reservoirs have 7 ports for maximum loop design options. On one end is a low profile three port cap and on the other end a 90 degree quad port cap. The quad port cap allows for a hidden inlet/outlet configuration, it also creates an aesthetic feature. Both caps have 3mm LED mounting positions to create a lighting feature and lighting up the coolant, the frosted acrylic version acts as a light diffusor. Protium has an aluminum retention ring design allowing the caps to be rotated to face any direction, this is something we don’t often see and is vital for clean loop design. There is no acrylic on acrylic thread and the o-ring surface does not rotate onto the o-ring, this increases quality and reliability.

Create a Combo:
To create the Protium D5 Pump and Reservoir Combo you need:
Protium D5 Pump Top.
Protium D5 Pump Cover.
Protium Reservoir.
D5 Pump (Any Standalone D5 Pump).

To create a Protium DDC Pump and Reservoir Combo you need:
Protium DDC Mod Kit.
Protium Reservoir.
DDC Pump.
