Introduction:

The MCX604-V™ heatsink is a high
performance, low noise thermal solution for Intel® Xeon™ processors
with 800MHz system bus (mPGA socket 604), code named "Nocona". This
heatsink is primarily intended for quality system builders and
integrators, and thus ships with a factory fan. The MCX604-V™ meets and
exceeds

Intel® Xeon™ thermal & mechanical design specifications
.

Features highlights

  • 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.

  • Quick and easy fan installation:
    the fan installs "in a snap" with convenient snap-in rivets.

  • 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.

* The C/W shown is the heat sink to air value, excluding
thermal resistance of the TIM joint, which will vary depending on the
thermal interface used and bench test conditions. For reference,
Swiftech’s TIM joint bench test value is 0.09°C/W. All tests are performed
in an environmental chamber using Industry standard procedures, and
calibrated equipment.
