DeepCool today introduced the Castle 360EX A-RGB, its top all-in-one, liquid, CPU cooler. The company made a handful updates over older generations of Castle EX AIOs. To begin with, the cooler features a dual-chamber pump with 2,550 RPM top speed. Updates have been made to the coolant path in this pump-block. The cold-plate has also been updated, with 25% more copper microfins. The pump-block is capped off with a new ARGB LED-illuminated infinity-mirror ornament that shows off the latest company logo.

The pump-block is plumbed to a 360 mm x 120 mm radiator which features an ambient air-pressure normalization mechanism DeepCool calls Anti-Leak Tech-Inside. This is basically a rubber bladder that swells when the ambient air-pressure is higher than the loop, to minimize leaks caused due to the pressure differential. Each of the three included CF120 fans features hydraulic bearings, turns between 500 to 1,800 RPM, pushing up to 69.34 CFM of air-flow at 2.42 mm H₂O pressure, and max noise output of 30 dBA. The cooler is expected to be priced around $170.
