The Aluminum Liquid Water Cooling Block is a high-efficiency thermal management component designed for high-performance cooling applications. Extruded from premium-grade aluminum with a clean brushed finish, this compact heat exchanger features an optimized internal flow channel to sweep heat away from intense hot spots rapidly. It features dual standard barbed nozzles that connect securely to flexible liquid cooling hoses. Perfectly sized for standard 40x40mm Thermoelectric Peltier Coolers (like the TEC1-12706), computer CPUs, graphics cards, and high-power LED arrays, this cooling block is a vital addition to custom liquid-cooled PC rigs and high-performance electronic builds.
