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.

This product is specifically designed to be mounted directly to a 120mm radiator. 140mm interchangeable back plates are also available separately. It can be mounted directly onto the radiator or with the fans in between. It can also be mounted to an empty radiator position, fan mounting position, any case panel, etc. It has 7 ports, 6 inlets and one outlet. Any of the inlets can be used, they can also be used as accessory positions for a drain port, temperature sensors etc.

Singularity brought you the original Reservoir to Radiator mounting system. This product mounts directly to any 120mm or 140mm wide radiator via our 120/140mm Universal Back Plate. For further mounting options look at our mounting components such as our Mounting Rails which provide incremental vertical adjustment. There is one outlet port but any of the seven inlet ports can be used and they can also be used for accessories such as fill, drain, temperature sensors etc.
