Key Features

Good Combination Of Heat Dissipation: The CPU cooler is composed of the top cover of the LCD panel + 4 heat pipe single tower + 2000RPM high-speed CPU fan, which can give full play to the heat dissipation effect of the cooler, and can also know the CPU temperature, CPU usage, and graphics card temperature at any time
2000RPM PWM Fan: The heatsink cooler is equipped with a performance-level fan speed of 2000RPM, and the cpu fan has a PWM function, which can adjust the speed according to the temperature of the motherboard, without manual adjustment. UL CLASSA safety insulation grade industrial grade PBT+PC material, as well as the S-FDB bearing of the fan, can well solve the problem of fan blade shaking in hoisting mode. Silicone corner pads around the fan can reduce the noise caused by rotation to a certain extent
AGHP Heat Pipe Technology: 4x6mm heat pipe adopts AGHP upgraded 4th generation technology, which solves the influence of anti-gravity caused by the vertical and horizontal mounting directions. Seiko heat pipe's direct contact process, HDT direct touch fine bottom surface treatment, combined with nickel-plated anti-oxidation heat pipes, so that the heat dissipation effect is improved
Detail Optimization: The 71mm width heatsink does not block the high vest of the memory when installed, and it is compatible with more memory. The SS2 fastener is compatible with a variety of CPU models, easy to install and remove, and easy to maintain and upgrade
Wide Compatibility: Heatsink compatible with dual platform (Intel 14/15th Gen + AMD RYZEN 7000) sockets: Intel LGA 1851/1700/1150/1151/1155/1156/1200; AMD: AM4/AM5; The radiator comes with an installation accessory that can be installed according to the installation video or manual.
