The open-loop liquid cooling system is made of all-aluminum brazing process with no risk of liquid leakage. The waterblock is an ultra-thin structure, which can dissipate heat in some tight spaces with limited height. This all-aluminum open loop liquid cooler is mainly used in servers and data service centers. The SP3 socket liquid cooling system is not only suitable for AMD SP3 socket, but also for other standard platforms or customized for other non-standard platforms without much hand assembly.
