The alphacool es reservoir for ddc pumps is specially designed for 1u server racks. The reservoir is extremely compact and integrated pump top for the ddc pump allows for extremely high pump performance. The large reservoir is more than sufficient for a liquid cooling loop in a 1u server rack. How can i connect the reservoir? The reservoir offers a total of seven g1/4'' connections, 1x out and 6x in.
