This is #12 in my series of triple radiators the EK-Coolstream RAD XTX (360). We previously looked at the more value oriented XT model which uses brass tubes and a slimmer 47mm with only two barbs. The XTX model I am looking at in this review turns performance up a notch by using copper tubes and a more premium 64mm thickness. In addition it provides several additional port options as well as an air bleed screw port feature for even more luxury level features.
A special thanks to EK for providing the review sample:
EK ultimate performance radiators are designed for extreme enthusiasts. These radiators are optimized for maximum heat dissipation even at lowest fan speeds. Choosing EK-CoolStream RAD XTX will give your watercooling system an upper hand you need to cool your hot hardware.
EK assured quality level and an optimal price-performance ratio make these EK-CoolStream RAD XTX radiators unique. The new radiators feature, besides their great design and high build quality, superb cooling performance.
The copper fins are optimized for both high- as well as low-speed fans therefore the new XTX radiator is an excellent all-around performer. The parallel flow cooling chambers reduce flow resistance to a minimum. Radiator shrouds are tapped with M3 threads on both sides to enable push-pull fan installation.
Radiator features G1/4 threaded ports on both sides of the radiator which enables various installation possibilites as well as stacking option. Bleed/fill/drain port, soldered to the bottom chamber, allows user a better overall handling and makes item more convenient.

The more important specs to note is the “90% Copper Tube” which has shown in previous testing to make a noticeable improvement over brass tube radiators of similar construction. I’m not quite sure what the 90% portion means other than it must not be pure copper, but I suspect it’s to give the copper a bit more rigidity since pure copper is fairly soft. Also notice the 64mm thickness which makes this radiator a bit thicker than even your typical premium radiator which range from 54 to 61mm…this one tops the thickness charts.
