Deepcool Gamerstorm Castle 240EX AIO review
AIO without leaks?

Today, we are reviewing an AIO cooler from Deepcool: the Castle 240 EX. It’s one of two variants of this new series (the bigger is a 360 mm). Both are equipped with Deepcool’s exclusive Anti-leak Technology. The technology helps the system achieve an automated pressure balance, which will significantly improve operation safety of AIO liquid cooling systems. Of course, there’s some RGB here (but only on the pump, not the fans), and what is new, is the option to customize the logo. The castle 240EX uses a very popular All-in-One formula, with a radiator, pump, and fans (2 x120 mm in this case) that are coupled into a single, closed-loop. The EX has skipped additional RGB accessories, and instead opted for a pair of four-pin TF120S PWM fans capable of moving up to 64.4 cubic feet of air per minute, with speeds ranging from 500 to 1,800 RPM


The Castle 240EX supports all major motherboard RGB systems, such as Asus Aura, as well as manual control via the included RGB controller. You can check out the default effects below.

We have received the 240 mm version of the Castle 240EX (there is also a 360 mm one available). From the technical point of view, the products look very similar to, for example, the Deepcool Castle 240 RGB, which we reviewed back in September 2018. The block is big enough to support the AMD TR4 socket without any adjustments needed. The pump is again huge and stands 71 mm tall. The top section of the pump has a mirror-like finish (when the lights are turned off) and a rim made of a silver-colored plastic. With addressable LEDs, the unit is still among the best-looking ones on the market.


The radiator is of standard size, namely 28.2 cm in length for the 240 mm model, with 2.7 cm in thickness and 10.5 cm in width. The radiator has aluminum fins instead of copper ones, which would have allowed for faster heat transfer (but it also costs significantly more). The MSRP is 119 USD for the 240 mm version. You receive 3 years of warranty, which is above the average on the market. Let’s check what this AIO has to offer besides the leak-proof technology and customizable logo.
