EK-CoolStream XE is a extreme-performance computer liquid cooling radiator which combines EK #39;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 XE series radiators a perfect choice for any computer water cooled system. This radiator offers best cooling capacity in the 60mm thick radiator class: Triple 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 four recessed G1/4 threaded ports with two pre-installed extenders from the front side to allow any G1/4 threaded fitting to be used. From the back side the ports are closed with two G1/4 plugs. EK recommends EK-ACF series compression fittings.
