Deepcool's Captain 240 PRO is an exceptional refresh of the company's all-in-one liquid cooler lineup. It took the visual appeal of previous designs, such as the unique pump, and paired it with a radiator that features a mirror-like accent on both sides. This gives the cooler a stunning appearance no matter what color of the rainbow you happen to prefer. Deepcool's desire to offer a good-looking cooler hasn't hurt clearance for memory or graphics cards either, so users looking to add tall RGB illuminated memory have nothing to worry about.

When it comes to user-friendliness, the cooler is very easy to install and exceptionally well built. The inclusion of Deepcool's patented Anti-leak tech which uses a bladder inside the radiator to regulate pressure is while hard to quantify, a potentially excellent addition as it should improve the lifespan and reliability of the cooler, thereby bringing some extra peace of mind to potential buyers. Warranty is another area where Deepcool does well with the Captain 240 PRO being covered for three years, which while not industry leading is still far better than the typical one or two years seen on some competing products.

Sadly, like most liquid-cooling solutions as of late, appearance takes priority over performance. While the Captain 240 PRO didn't perform poorly, doing decently well overall, it just happens to fall slightly behind some other liquid coolers with a couple of them being quieter as well. For example, the Alphacool Eisbaer LT 240 and Fractal Design Celsius S24 are both slightly quieter and better performers. The Reeven NAIA 240 also holds a noticeable performance edge, but only ends up 1 dBA quieter. Again, in general, the Captain 240 PRO is by no means bad, it just doesn't stand out on the performance or noise front.

Speaking of noise, at low to moderate loads, the Captain 240 PRO is pretty close to silent. You won't notice it over any other components in the system. However, with a heavy load on the processor and a decent overclock, you will inevitably hear the fans on this particular model. That said, the pump was whisper quiet and had no rattling, gurgling or other noises to speak of.

Overall, the Captain 240 PRO is a good all-rounder—it just doesn't take the top spot in any one category. This means you can make arguments for or against it in regards to much of its competition. However, if you truly want a unique-looking all-in-one liquid cooler that doesn't feature another boxy or circular pump with LEDs, the Captain 240 PRO is definitely worth a look!
