Ethereal Single was the first reservoir mount to directly attach a reservoir to a radiator, which has now become a standard in the industry. Ethereal Single 2.0 is an important update with many new features. The direct to radiator mounting back plate is now universal and includes both 120mm and 140mm mounting holes. The back plate has horizontal adjustment with 9 different mounting positions and an adjustment range of 80mm. This means that you can fit your reservoir or pump/reservoir combination into the tightest spaces. The mount now has a much lower profile of 80mm which is 9mm lower than the previous version meaning that it is suitable for the smallest cases. Ethereal Single 2.0 also has a new look with more detailed machining and chamfered edges.Singularity Computers Protium comboQuality:Created with a manufacturing process used in industries such as aerospace. All components are carved from a solid block of 6061 aluminum with extreme precision. Anodized for the toughest and most resistant surface available. Stainless steel fasteners for maximum strength and corrosion resistance. Silicone anti vibration pads with extremely high set point resistance. Compatibility:Ethereal Single 2.0 fits any 60mm reservoir or pump/reservoir combination on the market. It mounts onto any 120mm or 140mm wide radiator meaning 120mm, 140mm, 240mm, 280mm, 360mm, 420mm and 560mm radiators. It can be mounted to a radiator, onto fans or onto a radiator or fan mounting position. Do I need one or two mounts?All reservoirs or pump and reservoir combos will need one mount at the top and one at the bottom. If you are using Protium Pump and Reservoir components then there are other mounting options. So you could use two Ethereal mounts or you could use one at the top and then a back plate at the bottom. We have multiple back plate options but the 120/140 Advanced back plate is the most flexible. It can fit two Protium Pump Reservoir combos side by side at the same spacing and adjustment Ethereal Dual 2.0 or one with the same spacing and adjustment as Ethereal Single 2.0.
