After 15 years of creating the most extreme water-cooled PCs on the planet I have decided that the products currently on the market are not enough.
Protium like all of our products is refined in ways only possible from years of water-cooling experience. The caps can be rotated to face any direction thanks to our aluminium retention ring design. This also means that you don’t have the problem of an acrylic on acrylic thread which can be difficult to tighten. Protium is designed for maximum compatibility with 7 ports. The 90 degree ports allow for hidden inlets or outlets. We have created a feature with our caps with three different materials/finishes to choose from. With the addition of a single LED the acrylic caps can light up part of your build and cause the coolant to glow. The frosted acrylic version works as a light diffuser and creates a beautiful soft glow. Singularity Computers is known for quality, you only need to look at our portfolio from the last decade. CNC machined components, anodized aluminium, polished acrylic to a level you will not see anywhere else, evenly frosted acrylic and a perfect milled finish on the acetyl.

Protium reservoirs work perfectly with Ethereal and Core Reservoir Mounts.

    Will not thread onto pumpI bought this because it looked great online and I was going to use it on a pump/res combo from EK. You know, since they don't sell a pump res combo that isn't larger than a pee test cup. Looks like good quality, however, it will not thread onto my EK D5 pump. The threads look the same but it won't go. Pretty useless.... guess I'll return it and get the ugly one from EK.
