EK-XLC Predator Modular Liquid Cooling a Mid-Step to Open Loop

By Published October 20, 2015 at 5:24 pm

We've seen QDC – quick disconnect – liquid cooling solutions in the past, but they never quite came to fruition for general enthusiast use. Enthusiast brand EK Water Blocks, known best for its open-loop liquid coolers, has now announced its EK-XLC Predator 360 AIO with quick disconnect functionality. The 360mm radiator has the usual two tubes attached, but one uses a QDC valve for inclusion into a larger system. This modular AIO design makes an allowance for users interested in the concept of cooling beyond the usual CPU CLC, but who might be intimidated (monetarily or otherwise) by open loop solutions.

We're told that the QDC AIO is tool-less and eliminates the need for draining, using standard G1/4 threaded ports and 5/8” / 3/8” rubber tubing. The unit is pre-filled and connects with other pre-filled, compatible EK solutions – like GPU water blocks (pre-filled) with QDC compatibility. Coincidentally, EK hopes to make available QDC-ready GPU blocks on November 5th.

EK notes in its “technical highlights” that the cooler uses something they call “Hovercore,” which theoretically reduces chassis vibration initiated by the pump. This should reduce some of the pump noise introduced by other popular solutions.


The radiator uses an entirely copper core, a big difference from the aluminum radiators that dominate the market. Copper has a thermal conductivity (measured in W/mK) of nearly 2x aluminum, though its real-world efficacy can be questionable for relatively low-thermal PC components.

EK's pump is made by DDC and is PWM-controlled, so pump speeds can be regulated by the motherboard, pursuant to CPU temperatures and demand.

We'll have more coverage on the Predator as it nears launch.

Steve started GamersNexus back when it was just a cool name, and now it's grown into an expansive website with an overwhelming amount of features. He recalls his first difficult decision with GN's direction: "I didn't know whether or not I wanted 'Gamers' to have a possessive apostrophe -- I mean, grammatically it should, but I didn't like it in the name. It was ugly. I also had people who were typing apostrophes into the address bar - sigh. It made sense to just leave it as 'Gamers.'"

First world problems, Steve. First world problems.
