Deepcool at COMPUTEX 2019 showcased their current product portfolio - including the GAMAXX and CAPTAIn range - but also elected to showcase their latest brainchild: the CASTLE liquid cooling solutions. According to the company, they've developed an anti-leak technology that pretty much guarantees that your hardworking hardware will never sustain any kind of liquid damage should a fault occur with your unit. Essentially, this anti-leak technology works on the passive scale of risk prevention: it's a pressure balancing system that should reduce the likelihood of pressure-related malfunctions.The CASTLE series features an "ultra-large, pure copper CPU block", including for AMD's ThreadRipper CPUs. 16.7M colors RGB lighting is par of the course, and Deepcool says their E-shaped micro fin water channel is the best possible design for heat dissipation. The axles and bearings are ceramic-made, so as to guarantee a long service life. The CASTLe lineup is available in four products: the RGB V2, which comes with two RGB-lighting fans and is available in either 240 mm or 360 mm sizes; and the CASTLE EX, which is again, available in both 240 mm and 360 mm sizes, but makes do with non-RGB sporting fans.
