The cooler made of copper and aluminum comes with special 4D stereoscopic corrugated fins, six heat pipes with patented RDTH technology and a durable 140 mm dual blade fan. The integrated RGB LED lighting is compatible with Razer Chroma and the Zalman Z-Sync software. The Zalman CNPS20X CPU tower cooler at a glance: - CPU dual tower cooler made of copper and aluminum for best cooling performance - Special 4D stereoscopic corrugated lamellar structure - Six heat pipes with RDTH design for large contact area - Two 140mm fans with dual blade design for increased airflow - Addressable RGB LED lighting, compatible with Razer Chroma and Zalman Z-Sync - High RAM compatibility - Including high-performance ZM-STC8 thermal paste - Suitable for processors with up to 300 watts TDP - Optimized output airflow ensures more efficient cooling With the CPU cooler CNPS20X, Zalman relies on six heat pipes with RDTH technology (Reverse Direct Touch Heatpipe). The heat pipes are not directly on the IHS of the CPU. This creates a larger area where heat can be absorbed and dissipated. Thanks to its outstanding performance and efficiency, the Zalman CNPS20X is suitable for processors with up to 300 watts TDP (Thermal Design Power). The cooling fins are wavy. This special shape creates a total of 180 areas in which the air flow is channeled and turbulence is prevented. At the same time, this ensures that the air can flow evenly through the slats. This patented structure is referred to by Zalman 4D stereoscopic corrugated slat design. The enclosed fans are also special. The two 140 mm fans each work at 800 to 1,500 rpm and scoop up to 103.64 m³ of air per hour with a maximum volume emission of 29 dB (A). The dual-blade design of the rotor blades increases the airflow and ensures an effective channeling of the air flow. The durable FDB bearing guarantees a life expectancy of 100,000 operating hours. The special fan frame and anti-vibration pads minimize vibrations and disturbing noises. The central placement of the heat pipes and the high approach of the cooling towers to the base plate ensure high RAM compatibility. This means that RAM modules with their own oversized heat sinks can be installed, regardless of the direction in which the Zalman CNPS20X is placed. The striking, integrated RGB-LED lighting of the two fans is compatible with Razer Chroma and the Z-Sync software from Zalman. The lighting can be easily synchronized with other RGB components via a 3-pin header connected to a mainboard or RGB controller. Installation is childs play thanks to the sophisticated mounting system and Zalman includes the ZM-STC8 with a strong thermal compound.
