EK-CoolStream PE is a high-performance computer water-cooling radiator which combines EK's unique CSQ design with latest radiator core engine. Built for EK-Vardar 120mm high static pressure fans, these radiators are optimized for maximum heat dissipation across entire fan operational range thus delivering exceptional performance at both low- and high airflow operation. EK assured quality level, optimal price-performance ratio and unique minimalistic design make these EK-CoolStream PE series radiators a perfect choice for any computer water cooled system. This radiator offers best cooling capacity in the 40mm thick radiator class: Double stack copper fins provide massive surface area while the parallel flow cooling chambers reduce hydraulic flow resistance to a minimum. Radiator shrouds are tapped with UNC 6-32 threads on both sides to enable push-pull fan installation to even further increase the cooling performance. This product features two recessed G1/4 threaded ports with pre-installed extenders to allow any G1/4 threaded fitting to be used. EK recommends EK-ACF series compression fittings.
