ID-Cooling at its Computex 2019 booth showed off a vibrant selection of illuminated cooling products, particularly its new line of compound fans. These are essentially a row of 2-3 fans under a single unit, so it could be conveniently mounted onto a radiator, minimizing fan-cabling and screws. The first of this kind is a 360 mm x 120 mm unit, with a trio of 120 mm spinners resembling the XF-12025. The RGB LEDs are embedded into the impeller hub, and the frosty-translucent fan-blades act like diffusers. The second kind has completely opaque black fan impellers resembling the ZF-12025, but acrylic aRGB LED diffusers are embedded into the frame. Each of the three fans in the XF-12025-like compound fan spins between 700 to 1,800 RPM, pushing up to 55.2 CFM of air, with a noise output ranging between 18 to 35.2 dBA. The ones in the ZF-12025-like compound fan spins between 900 to 2,000 RPM, push up to 74.5 CFM of air, with a noise output ranging between 16.3 to 33.5 dBA.ID-Cooling has applied the concept of compound, indivisible fans, even to its all-in-one closed-loop cooling solutions. The company showed off two kinds of unnamed CLCs, one for CPU, and the other for graphics cards. Both use a shrouded 240 mm x 120 mm radiator that has 120 mm aRGB LED-illuminated fans suspended onto the shroud. In addition to lighting from the fans, an acrylic RGB LED diffuser accent runs the perimeter of the shroud. The pump appears to be embedded into the radiator unit, rather than the block. The water-blocks of both coolers appear to be DIY-quality, with chunky copper primary material replacing a thin cold-plate. The CPU block has a metal top with plastic inserts, while the VGA full-coverage block has an acrylic top studded with aRGB-LEDs.We also ran into the PinkFlow, a fabulous Hello Kitty-esque feminine-looking CPU CLC which combines soft-pink with silver accents. Pink dominates the body color of the blocks and fan impellers, while white covers the rest. The ID-Cooling logo on the block itself is twisted to the shape of a heart. For those who prefer a lot fewer moving parts and staying dry, the company unveiled an unnamed tower-type CPU cooler that features an aluminium fin-stack with twisted fins to maximize heat-dissipation, and a single XF-12025 120 mm spinner. The cooler is topped-off by a plastic top-plate that has an X-shaped RGB LED diffuser.
