The DEEPCOOL Captain EX 240 RGB Cooler

The DEEPCOOL Captain EX 240 RGB is a classic CPU-only AIO cooler design, with the CPU block assembly attached to the radiator via two hoses. The CPU block assembly includes the CPU contact plate, the pump, RGB LED lighting, and the speed control electronics. All of the parts are black. The tubing is thick and has a nylon braiding surrounding it. It is not very flexible but it certainly is very tough. DEEPCOOL has the tubing entering the CPU block assembly from the side, using 90° joints.

The radiator of the kit is a typical two-pass design, very similar to that used by almost every 2×120 mm fans AIO kit in the market. It is 275 mm long, 120 mm wide and 27 mm thick (10.83 × 4.73 × 1.1 inches). Its narrow dimensions suggest that a push-pull fan configuration will not provide reasonable performance benefits, as it has little airflow impedance to begin with. The design is common and that is not a bad thing, as it is proven to provide relatively good performance. Interestingly, it has a visible refill port but DEEPCOOL has sealed it.

The highlight of this cooler is the CPU block. It is almost cubic in shape, with the company logo etched on the sides of the assembly and a decorative fin circular array on the top. DEEPCOOL has designed it so as to make the liquid flow visible to the user via a clear plastic tube that comes out of the assembly’s center and goes back in from the side. The downside is that it has two wires, one power wire for the pump and one for the RGB LEDs. The wire for the RGB LEDs need to be connected to the bundled cable with the attached controller for the RGB LEDs to work, requiring a SATA power connector and skillful cable routing to hide everything.

The RGB lighting of the Captain EX 240 RGB is somewhat limiting, as the user can only choose from seven solid colors (red, blue, green, magenta, cyan, orange, and white), or from a couple of basic pre-programmed visual effects. Unfortunately, the included controller is unable to generate any other configuration. However, it can be replaced by a more advanced aftermarket controller or be connected directly to a header of a motherboard that offers onboard RGB strip support, as both the included strip and the integrated LEDs are typical 4-pin RGB products.


The square copper contact base of the Captain EX 240 RGB is attached to the main body of the cooler via large and visible Allen bolts. It comes with the thermal compound pre-applied and is polished to a very smooth, yet not a mirror finish. The DEEPCOOL Captain EX 240 RGB supports AMD AM4 but not TR4 CPUs.

    I have an NHD-15 heat sink and I also have a corsair h80i v2. (my case, a silverstone FT1 does not easily support radiators larget than 120mm) My CPU is an older 3930K six core that warms up nicely... Of course I do not have all the nice test bench stuff that Anandtech has, so my results are quite a bit more touchy-feely. By just a whisker the NHD-15 is both a tad quieter and a tad cooler.... I also like the fact that I know that outside of the fans there are no moving parts to fail.

    I am sure that my limitations are the 120 mm radiator, and I am also pretty well convinced that within a given sized radiator, there will be a very narrow range of test results across the range of AIO kits. But I keep looking...

    Thank you, Mr. Fylladitakis for your review.

    Since the advent of AIO liquid cooling kits my personal builds have changed a good bit. Have a H100i on my main build for a few years now, and my old and trusty second machine has a Hyper 212 EVO on it.

    I've had bad experiences with heavy air coolers in the past, so I tend to stay away from them these days. My cases have positive pressure and the H100i works well as an exhaust mounted at the top.

    To each their own. I know several people that frequent this website are still fond of air cooling, and in many situations it's still a very good and efficient option but in the end I'd say it depends on what kind of build you have in mind.

    how long are these coolers being run at load?

    For all the commentary about the bench -- this deepcool is not in the Anandtech bench section. ...
