Silent-Pipe 3™ is yet again changing the face of silent graphics card solutions, combining three GIGABYTE proprietary thermal designs: Silent-Pipe II™, Silent-Pipe™ and Screen-Cooling™ Silent-Pipe 3™ delivers the very latest in passive cooling technologies. Similar to the principle of turbulence in fluid dynamics, Silent-Pipe 3™ introduces Inner Turbulence Fluid Mechanics Design. Utilizing a series of layered long and short fins with trapezoid punches, Silent-Pipe 3™ transforms laminar (smooth) air flow into turbulent (rough) air flow inside the heat sink, increasing the heat exchange ratio and enhancing overall thermal performance.
