Swiftech MCX775-V heatsink,Intel socket LGA775

• Optimized performance characteristics at the lowest possible audible noise levels.

• Hybrid copper base, thin aluminum pin heatsink: the massive 1/2" thick copper base provides superior heat capacity for unparalleled stability in extreme load applications. The thin aluminum pins promote increased turbulence for more efficient heat dissipation compared to traditional fin extrusions.

• Patented Helicoid pin design (U.S. patent 6,469,898): pins are individually machined in an helicoid shape, to increase their surface area, and further enhance heat dissipation efficiency.

• Several patents pending for concentrically aligned rows of pins, bent at multiple angles. The spacing and angles between the concentric rows has been precisely calculated to optimize cooling and reduce noise at air flow levels as low as 22 CFM and 23 dbA.
