Our CES 2019 party continues with a visit to Deepcool who had some sleek cases and cooling products on display. Highlights include a high-end air cooler, feature-rich ATX case and a new AIO water cooler.


Assassin III Heatsink

The Assassin III heatsink comes in at a blistering 280w TDP, on par with some AIO water cooling solutions we’ve seen. With claims like that, it may even have the chops to challenge the Noctua NH-D15 for air cooling supremacy. We’re looking forward to testing them head-to-head in a future review.

This cooling performance is accomplished by several unique features. First, this dual tower, nickel-plated air cooler is designed so that the 140mm fans sit slightly higher than the top of the heatsink. This additional space, coupled with a “spoilers” on the top of the heatsink helping to move more air through the fins and gives a bit more clearance over the RAM. Second, and maybe most important, the seven heatpipes use a hybrid sintered and grooved technology. According to Deepcool, most heatpipes are either sintered or grooved, not both. By employing both methods, Deepcool claims 15% better cooling performance than standard heatpipes.

To firmly position this cooler at the top echelon of air cooling, Deepcool includes a deluxe accessory package with a custom screwdriver to make installation a breeze. The Assassin III should hit the shelves in May at a $99.99 MSRP.

Castle 360 RGB AIO Cooler

The Castle 360 RGB AIO features a 280w TDP and copper CPU block. Double windows on the waterblock give the lighting a sort of “infinite” feel, where you cannot see where the lighting ends and waterblock begins. The Castle 360 RGB will be available this month and retail for $169.99.

Captain 240 Pro AIO Cooler

Although the Captain 240 Pro is not a new product, Deepcool has done a refresh of sorts to stamp it with the “Never Leaks” monicker. This was done by adding a patented, “Automatic Pressure Relieving” system to the radiator. By reducing the pressure when the water temperature increases, they say the unit is far less likely to leak. In order to accomplish this, Deepcool placed a rubber capsule inside the radiator that expands or contracts based on the pressure in the system. Deepcool plans to bring this technology to the rest of their product line in the future.

Macube 550 Case

Deepcool’s new flagship case is dubbed Macube 550, featuring a clean, minimalistic design. The case offers unique front and side panels. Rather than the standard four thumbscrews, the side panel is grooved at the bottom to slide into the case and is held on at the top by magnets. This makes accessing the system easier. The front panel features a “levitation design,” which allows for additional air intake when compared to other cases. The opposite side panel has grooved, shark fin meshed openings that allow even more air to flow through.

The Macube 550 will be available in both black and white for $109.99 and $119.99 respectively starting in June.

Mattrex 70 Case

Moving to a more budget-conscious option, the Mattrex 70 offers “one-touch” front panel removal, two thumbscrew side panel design and a tempered glass PSU shroud. By separating the PSU chamber from the case, it gives users more options for hiding wires and helps reflect light from RGBs. This is E-ATX case can support radiators up to 360mm and soft, flexible, magnetic dust filter on top. The Mattrex 70 will hit stores in April at a low $69.99 MSRP.

  1. My thermodynamics background is a little...nonexistant. Does water (or whatever liquid is being used) really expand enough in the space of 40c or so to risk damaging an AIO cooler? I mean I've heard of more cases of pumps failing over the things cracking due to any thermal pressure :shrug:
    Don't get me wrong, I'm interested enough that I'll probably go with some sort of AIO for my next mobo/CPU upgrade and will definetly look at what Deepcool is offering, just sounds like this "pressure relief system" is more so they can toss another marketing label on it lol.
    I would think the very little expansion of water in the temperature delta range we are looking at would easily be compensated for by stretching in the hoses.

    Yeah figured as much, thanks.
    Eh, they've had some leakage issues in the past, if Google is to be believed. I think mostly at the swivel joints at the pump/block. So maybe not completely fluff. If nothing else it allows them to point to something being done, directly related to a problem. I'm happy to see Deepcool expanding, myself. I've been nothing but happy with my AIO from them. It's been a really good performer, especially with the ambient temps I get here.
