Jet Engine-Inspired Cooling Design Inspired by jet engines, the ZET5 showcases Zalman's latest design and performance innovations Clean and Modern Logo Design Magnetic & Pogo Pin Mounting System High-Efficiency Dual-Directional Cooling Fans Powerful 120mm Annular Fan Zalman AF120 annular fan is designed to prevent vortex and backflow at the end of the wings, which can improve efficiency and stability by suppressing vibration. High-Performance Circular Heatsink 53 Heatsink Fins Deliver Superior Cooling Efficiency TDP 220W Supports motherboard ARGB control for vibrant LED Sync RDTH(Reverse Direct Touch Heatpipe) Zalman’s RDTH technology is applied to minimize thermal resistance and maximize cooling performance DTH(Direct Touch Heatpipe) Direct heat transfers to heatpipes maximize cooling performance and minimize heat resistance RDTH(Reverse Direct Touch Heatpipe) RDTH allows larger dissipation area of heatpipes and minimize heat resistance Direct Solder Bonding for Maximum Efficiency Direct soldering between the heatpipes and heatsink allows for ultra-precise contact, significantly enhancing heat transfer efficiency. Excellent thermal conductive thermal compound ZM-STC10 Zalman ZET5 comes with ZM-STC10. STC10 provides ideal heat transfer to keep PC cool and ready for heavy loads. It provides excellent thermal conductivity by filling the space between the cooler base and CPU.
