Finally EK is ready to offer you radiators designed for hardest enthusiasts. Radiator is optimized for maximum heat dispatching even at lowest fan speeds. Choosing EK-CoolStream RAD XT will give your watercooling system a boost you needed to cool your hot hardware.
Quality at EK level and an optimal price-performance ratio make these EK-CoolStream RAD XT radiators unique. The new radiators feature, besides their great design and high build quality, great cooling performance.
The copper fins are specially designed for Ultra-silent fans (with low Airflow). The parallel coolant channels reduce flow resistance to a minimum. On both sides of the radiator the M3 threads are integrated to allow fan installation on both sides and radiator mounting.
The radiator has integrated G1/4" threads, allowing installation of virtually all common fittings.

The product is quite heavy and large which sorta threw me off but still NO problems installing. Id like you all to keep in mind that the in/out ports are right next to each other and there are NO other ports on the other side. this works out quite nicely if you have a bay resevoir (i do) to go right below it. I do wish it had ports on both sides though, i ignorantly assumed it did for some reason i cannot explain which made me redesign my loop a bit when it arrived but still, VERY satisfied with the quality.
Great Rad!!

replaced my old (major brand) radiator with this EK and my temps are 5C lower! High quality construction, you can *feel* the weighty copper in there.
