-10% Singularity Computers Protium 150 D5/Reservoir Combo Acetal (Stand Alone)


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.

Unmatched quality and versatility. 8 Ports at 90 degrees and full 270 degree rotation so that you can mount to face three different directions. 360 degree rotation for the reservoir cap. Spare ports for temperatures sensors, fill and drain. This Reservoir/D5 combo comes with our Universal 120/140 Back Plate which means that it can be directly mounted to any 120mm or 140mm wide radiator without any other mount being needed. We wanted to create more options for customers who are still looking for Singularity Computers premium quality and versatility, but don’t need all of the components which come included with our Protium Reservoir/D5 Ultimate Combos.

New Revision 2 Protium D5 Pump Top:

Perfection is something which can never be achieved and so above all things we believe in progress. We are now up to revision 42 of our pump top as we have been slowly trying to perfect it over the years. After hundreds of small but important changes, we have now decided it is time to announce our new version. Revisions include flow and performance optimizations, thickening and strengthening. We have also improved our manufacturing process, precision and our surface finishes, specifically our polished acrylic which is now truly crystal clear.
