The 120/140 Advanced Back Plate is designed to mount Singularity Computers components directly to any 120mm or 140mm wide radiator, fan or fan mount. It provides 12 increments and 140mm of horizontal adjustment. This means that you can offset your components from one side of your radiator to the other. It is compatible with all of our Reservoir Mounts and Protium Pump Tops. Many configurations are possible including mounting two Protium pump tops side by side in a dual configuration.
