EK-CoolStream SE is a slim, high-performance computer liquid cooling radiator which combines EK\'s unique CSQ design with latest radiator core engine. Built for EK-Vardar 140mm 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 SE series radiators a perfect choice for any computer water cooled system. Overall compact measurement of the SE series radiator allows for utilization even in the tiniest computer chassis.This radiator offers best cooling capacity in 28mm thick radiator class: 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 two pre-installed extenders to allow any G1/4 threaded fitting to be used.
