There is a new combo water cooling unit in town, one that combines the benefits of a water pump and reservoir.
Created by Ljubljana-based premium water cooling gear manufacturer EK Water Blocks, it is called EK-DCP 4.0 X-RES.
It is made of POM Acetal material (the tube is made of casted acrylic material) and is fully air- and waterproof. It can be closed with bundled plugs, preventing water evaporation.
It also has a vibration-dampening design and comes with a coolant level monitor.
EK-DCP 4.0 X-RES should be able to move 800 liters per hour at little to no noise.
EK should already be shipping the product for €89.41 / $120.76, or for €45.70 / $61.73 without the pump. Installation should be easy.
The option without the water pump exists because said pump has been shipping for some time, so people may already own it.
