Jonsbo today introduced the CR-301 RGB top-flow CPU cooler. Designed to handle thermal loads of up to 135W, the cooler supports mainstream-desktop sockets, including AM4 and LGA115x. Its design involves two independent aluminium fin-stacks that propagate along the plane of the motherboard, which draw heat from the base via heat-pipes. Heat to the upper main cuboid fin-stack is supplied by four heat-pipes, while it's fed to the smaller lower truncated-pyramid shaped fin-stack by two heat-pipes. All six heat-pipes are 6 mm-thick.

Ventilating the two fin-stacks are two 120 mm PWM fans with RGB multi-color LED lighting. The upper fan is to be installed above the upper fin-stack, and the lower fan between the two fin-stacks. Spinning at speeds of 600 to 1,600 RPM, the fans push 23.8 - 76.6 m³/h of air, with a noise output of 18.0 - 25.0 dB(A), each. Together the fans blow air downwards, and the fins of the lower stack guide air onto the CPU VRM and memory areas. Besides AM4 and LGA115x, the cooler supports AM3(+), FM2(+), and LGA775. Measuring 128 mm x 138 mm x 135 mm (LxWxH), the cooler weighs 890 g. It will be sold under the Cooltek brand in the EU. The company didn't reveal pricing.
