Key Features

  • [158mm Heat Dissipation Height]The overall height of the cpu cooling is 158mm, which is compatible with more chassis. The main body is made of all aluminum fins, which can provide a larger heat dissipation area
  • [Dual CPU Fan Cooling]The matched 120mm and 140mm fans have a speed of up to 1850RPM and 1500RPM, and an air volume of 88.89CFM and 77.8CFM, which can provide good heat dissipation effect. The fans have PWM function and can adjust the speed according to the motherboard temperature without manual adjustment. The attached fan hook is fixed on the twin tower radiator.
  • [AGHP Heat Pipe Technology]The 6x6mm heat pipe adopts AGHP technology, which can solve the impact of reverse gravity caused by vertical/horizontal installation orientation. Precision micro carving reflow soldering with nickel plated copper base, combined with nickel plated anti-oxidation heat pipes, improves the heat dissipation effect. DTPC is 275W.
