Product Overview

The MCX64-V follows the high performance-low noise tradition of our "V" series heatsinks, and is designed to operate with AMD® Athlon 64 and Opteron (socket 754, 939 & 940) processors.

This model is specifically designed to comply with AMD® mechanical specifications, while surpassing the thermal and acoustical requirements. The MCX64-V is primarily intended for OEM's, system integrators, and users who desire to keep their cooling solution in strict conformance with AMD® specifications, while offering top notch cooling performance at low audible noise levels.

  • Hybrid copper base, thin aluminum pin heatsink: the 3/8" thick copper base provides excellent heat capacity and lateral heat dispersion. 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 dB-A.
  • The MCX64-V™ ships equipped with an 80x25mm fan chosen to do better than AMD® 's lowest recommended audible noise levels, while maintaining compliance with the specified thermal resistance See fan specifications here
  • Exceptional quality and attention to details: the heatsink base is lapped to 0.0003" (3/10 of 1/1000"), and polished to near-mirror finish to promote optimum thermal conductivity. Users are advised that while flatness is strictly respected for providing the most significant benefit to thermal interface, surface polish is a cosmetic component and may vary slightly from one heatsink to another. Re-lapping or polishing the heatsink base is never recommended.
Motherboard and CPU compatibility
The MCX64-V is compatible with all known Athlon 64 and Opteron motherboards at the time of this release.

Retention Mechanism
  • The MCX64-V is designed to be used with AMD® recommended retention frame and backing plate.
  • The spring loaded mechanism provides a safe and effective attachment method to the motherboard, and complies with AMD®'s static and dynamic load specifications.

  • Because a majority of motherboard manufacturers already include the retention frame and backing plate with their offerings, and in an effort to spare this cost to the majority of users, Swiftech does not include these items with the MCX64-V™ heatsink. These items are nonetheless offered as an option under part # AJ00172, as shown below.
    Part # AJ00172 complete retention frame & backing plate
  • Users are advised to inspect the backing plate shipped with their motherboard, and to note that a metallic backing-plate featuring threaded standoffs is required. An example is shown below, and is available under part # AJ00264.
