Noctua is reportedly working on a high-performance fanless CPU cooler building on a 2019 prototype that was exhibited at last year's Computex. The final product should launch within 2020, according to an Overclock3D report. As of now there's no word on whether the said cooler will look identical to last year's prototype, but it provides a long list of capabilities that Noctua could build on. For starters, last year's prototype was capable of handling 120 W TDP in PC cases with good natural ventilation, and up to 180 W in cases with quiet fans. The company used a Core i9-9900K in a variety of workloads as a proof of the heatsink's capabilities. The prototype heatsink was also shown offering decent amount of clearance with the motherboard's memory- and VRM areas. Its only downside was the 1.5 kg weight.
