This is the ideal top for the Alphacool DC-LT pump. This top is designed in such a way to allow mounting on the Alphacool DC-LT pump. With the top, it is possible to integrate this miniature pump into your water cooling loop via ?" threads.?The inlet fitting can be connected on the side or on top of the unit. The outlet is then connected to the opposite side. All silent system enthusiasts will be happy to hear that threads were implemented to allow decoupling with e.g. Item No. 13701. With these decouplers the pump and top can be mounted in a 3.5" drive bay. Thought was also given to the case modders, as a 5mm LED hole near the outlet allows unique lighting effects for your system.
