The HAVN HS420 D5 Reservoir Distribution Plate fits onto any 420mm radiator mount but is specifically designed for the HAVN HS420. It is intended to be used instead of a radiator or fans but it could be used in combination with them if stand offs or spacers were used for airflow. It has an integrated reservoir, D5 pump top, D5 Pump Cover, Fill and Drain Ports. It is built from CNC machined clear cast acrylic and uses gaskets instead of O-Rings for increased durability. It is hand assembled with stainless steel fasteners. It has an integrated ARGB LED strip with an Accent Cover. There is also an optional Back Plate included to cover the rear side of the Rear Distribution Plate, so that you can’t see the case panel behind it.
