Jonsbo introduced the futuristic-looking CR-401 air CPU cooler. The U-type aluminium dual fin-stack cooler features a monolithic industrial design thanks to the metal shroud concealing the sides and top of the fin-stacks, and a discrete 120 mm fan between the two fin-stacks underneath. The top features an RGB LED lighting diffuser, while keeping up with the black color-scheme of the shroud, the aluminium fin-stacks and heat-pipes are black. Five coated copper heat pipes make direct contact with the CPU at the base, with their two ends passing through the two fin-stacks; which are ventilated by the 120 mm fan between them in pull-push configuration, which has an RGB LED-illuminated frame of its own.

The discrete 120 mm fan takes in PWM input, spins between 800 to 1,600 RPM, with a noise output ranging between 18 to 25 dBA, although the company didn't list its air-flow. Measuring 125 mm x 88 mm x 165 mm (WxDxH), the CR-401 weighs 860 g. It is rated by its designers for thermal loads of up to 135W, and hence only supports today's mainstream-desktop CPU sockets, including AM4, AM3(+), FM2(+), and LGA115x. The RGB LED elements of the diffuser and fan take in standard 4-pin input, and support a 256-color palette. The company didn't reveal pricing.
