EK-CoolStream CE is a 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 optimised 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 CE series radiators a perfect choice for any computer water cooled system.This radiator offers best cooling capacity in the 45mm thick radiator class: Dual 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.Specification: - Material: Copper fins, 90% copper tubing (H90), Brass chambers, Aluminium/Steel housing- Dimensions: 320 x 145 x 45mm (L x W x H)- Weight: 1.12kg- Liquid Capacity: 290mL- FPI: 16- Port threads: 2x G1/4- Fan compatibility: any standard size 140x140x25mm fan; UNC 6-32 thread tapping- Pressure tested: 1bar(g)Contents: - EK-CoolStream CE series radiator /w two pre-installed G1/4 extenders- Flat-head UNC 6-32 screws (l=30mm)- Flat-head UNC 6-32 screws (l=5mm)- Allen key 2,5mm
