Today we are having a look at the EK-XLC Predator 240, the first AIO liquid cooling solution from EKWB. EKWB is a company that specializes in and is known by their custom liquid cooling products, but with the EK-XLC Predator 240, the company is trying to bring the performance of their custom liquid cooling solutions to the AIO market. We are thoroughly examining and comparing their new product in this review.


Ever since liquid cooling became a small trend in the 90's, when enthusiasts were using car radiators and aquarium pumps to cool down their heavily overclocked Athlons and Durons, many companies were founded, focused on custom advanced cooling solutions. However the combination of the relatively high cost and complexity of a liquid cooling system, plus the increasing energy efficiency of modern processors, kept demand for such systems and parts low. As a result, very few of these companies survived to this date. EK Water Blocks, or EKWB for short, is one of them.

EKWB is a company that originates from Slovenia. They are one of the oldest liquid-cooling focused companies around and today they are certainly one of the most popular PC custom liquid cooling manufacturers. They are mainly focused on designing individual liquid cooling parts, such as motherboard and GPU-specific cooling blocks, reservoirs and radiators. However, the bulk of the interest on liquid cooling systems today is on all-in-one (AIO) solutions that are ready to be installed and operate with little knowledge beyond knowing how to install a basic PC. EKWB has realized that and recently released two ready-to-go AIO cooling kits with a twist - these can also be upgraded and expanded. Today we are having a look at the EK-XLC Predator 240, the "small" kit that is featuring a 240 mm radiator.

Packaging & Bundle

The cardboard box that the Predator 240 came in is not particularly strong but the product is very well protected within a plastic shell inside it, ensuring that it will be delivered without damage. The artwork is simple, direct and elegant, mainly focused on a picture of the unit itself and it promotes its most significant features.

EKWB supplies the most basic bundle that we have ever seen coming with an AIO cooler. Inside the box we only found the power cable that is necessary to power the unit (a derivative of a SATA power cable), a few mounting screws, a Torx driver, thermal paste and a user's guide. The user's guide is by far the most interesting piece of the bundle, being well-written and illustrated, making it very useful. Note however that certain parts of the guide assume that the user is a fairly advanced DIY enthusiast, suggesting, for example, the removal of the CPU's lid or the internal cleaning of the water block. The instructions are detailed enough for an advanced user to partake such tasks, describing the process and the tools/chemicals/substances that may be necessary. However, several of these recommendations are absolutely not for amateurs and could result to major equipment damage when not performed adequately.

    We gave out a bunch of those AT-branded screwdrivers a while ago! They conveniently feature a reversible Phillips/flathead tip. We don't have a full set of branded tools, but if there is sufficient interest, we're happy to find a way to give away some more screwdrivers!

    Put me on the list, I want one :)

    My first though was, cool where can I get one. If they were for sale I'd have bought a few to give as gifts this holiday season, depending on price of course =)

    I would love an AT branded screwdriver!

    Does H110 in the figures mean H110, H110i GT, or H110i GTX? If it is just the original H110 AIO cooler, that's a bit disappointing since the H110i GT is a direct upgrade over the original and is the most likely AIO alternative to the reviewed product.

    Comparison with some high-end air cooler (Noctua NH-D15 comes in mind) would be helpfull.

    The EK Vardar fans are comparable to the venerable Gentle Typhoon series as being the best radiator fans on the market. The Vardar fans are extremely quiet even when at high speeds (3000 rpm). I picked up one of the FF5 120 mm PWM fans when they first came out for some viability testing and couldn't believe how quiet they were at full speed. It's no surprise to me that they have excellent cooling ability with low fan noise.

    (Facepalm) Why don't you compare this to AIR? Noctua 14/15 blows away almost all of these coolers in performance AND sound.
  • Ninhalem - Wednesday, December 16, 2015 - link

    And why would I want something clunky like the Noctua 14 hanging off my motherboard when I have space restrictions that a water cooling system like this product could solve handily?

    It would be useful to get the comparison. Air can be better for your setup, Water can be better for your setup - details matter. But it doesn't make the performance and noise comparison useless.
