Swiftech MCX64-V and MCX6400-V Heatsink Fan

Manufacturer: Swiftech


Swiftech has been supplying high-end cooling solutions to PC enthusiasts and overclockers for many years.  Founded in 1994 as a Maintenance and R&D organization for Unix computers and imaging systems, Swiftech has expanded their product offerings to include air-cooled, water-cooled, and active thermoelectric (Peltier) cooled heatsinks.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />


Swiftech provides some of the finest waterblocks, complete water-cooling system kits and thermoelectric coolers to meet the needs of the hardcore overclocking community.  They also continue to offer a full line of air-cooled heatsinks.  In this review, we will be looking at two of their latest air cooling products, the MCX64-V and MCX6400-V heatsinks.


The Swiftech MCX-V series of heatsinks are designed to be high performance-low noise cooling solutions.  They are available in five different mounting styles to accommodate all the popular CPUs and socket configurations.  The MCX6400-V is a larger, heavier version of the MCX64-V intended for extreme applications and operating conditions.

  • MCX462-V  AMD socket 462

  • MCX478-V  Intel P4 socket 478

  • MCX603-V  Intel Xeon

  • MCX604-V  Intel Xeon (800 MHz system bus)

  • MCX64-V   AMD Athlon 64 and Opteron (OEM)

  • MCX6400-V  AMD Athlon 64 and Opteron (Extreme)

Both the MCX64-V and MCX6400-V heatsinks incorporate hybrid construction, which uses an array of aluminum pins pressed into a solid copper base.  Each pin is machined in a helicoid shape, to increase surface area for enhanced heat dissipation.  After insertion, the concentric rows of pins are bent outwards to further optimize cooling and reduce noise.


The MCX64-V comes fitted with a low speed 80mm fan and has been specifically designed to comply with AMD mechanical specifications (size and weight), while exceeding the thermal and acoustical requirements.  The MCX64-V is primarily intended for OEM's, system integrators, and users desiring a high performance cooling solution that strictly complies with AMD specifications.


The MCX6400-V offers extreme performance for AMD socket 754/939/940 users.  It is the heaviest, and features a larger number of pins for higher heat dissipation than any other Swiftech heatsink.  The MCX6400-V does not come with a fan, which allows users to customize the product to their particular needs.
