Key Features

  • [Heat Dissipation Combination] The CPU cooler is a double-tower dual-fan structure, with a blackened anodic matte top sheet + 6 fully electroplated anti-oxidation heat pipes + Seiko micro-carved reflow soldering nickel-plated copper bottom, with a 2000RPM high-speed PWM fan, which can easily dissipate the CPU temperature and further improve the heat dissipation efficiency of the cooler.
  • [Good Bearing] The S-FDB bearing of the PC fan can well solve the problem of shaking vibration of the fan blades in the lifting mode, and the silicone corner pads around the fan can reduce the noise generated by rotation to a certain extent, so that the radiator can have a longer service life.
  • [Dual PWM Fans] with 120mm performance dual fans, up to 2000RPM, large air volume can bring good heat dissipation effect, the fan has PWM function, according to the temperature of the motherboard to adjust the speed, no need to manually adjust. The included fan hook can be securely hung on the twin towers for cooling.
  • [155mm Heat Dissipation Height] The overall height of the heatsink is 155mm, which can be compatible with more cases. The main body is full of aluminum fins, which can bring a larger heat dissipation area
  • [Wide Compatibility] The cooler is compatible with dual-platform (Intel 14/15 generation + AMD RYZEN 9000) Slot: Intel LGA 1851/1700/1150/1151/1155/1156/1200; AMD: AM4/AM5; The cooler comes with mounting accessories, which can be installed according to the installation video or instructions.
