Dynatron G666 2U Xeon Server Heatsink Review
  77%   
Abstract: The heatsink is built with a 60mm fan embedded at the front, directing airflow through a short stack of aluminum cooling fins which are connected to a copper base plate by three 6mm diameter heatpipes. The space before and after the heatpipes is filled with two narrow strips of skived copper fins for added cooling surface area.

FrostyTech Mk.III Synthetic Thermal Heatsink Test Results
Intel Core i7, Extreme Edition class heatsinks tested at a 200W heat load.
Results based on readings from a 38x38mm copper interface die with 200W heat load on the Intel version of the Mk.III Test Platform. Temperature results listed for each heatsink were calculated by determining the rise over ambient temperatures at time of test. Information on Frostytech's test methodology is available here.

200w thermal test (°c) noise level (dba)
*heatsinks are ranked according to the 200w thermal test results column (rise over ambient temp.). low temperatures with low noise levels are considered best. for reference heatsinks with variable-speed fans, only the high speed (12v) fan test result is included in the comparison sheet; more detailed results reside in each specific heatsink review.

Frostytech's socket LGA2011 Intel synthetic thermal test platform stresses socket LGA2011/LGA1366 compatible heatsinks with a 200W heat load. Keep in mind that the AMD Integrated Heat Spreader and Intel LGA2011 Integrated Heat Spreader both measure ~38x38mm, so these test results can be extrapolated to AMD processor scenario's as well.

With a 200W heat load applied by the Intel LGA2011/1366 version of FrostyTech's synthetic thermal test platform, the Dynatron G666 2U Xeon server heatsink was able to maintain a satisfactory temperature result of 31.8°C over ambient, at stock fan speed (8000RPM / 68.7 dBA). For a heatsink that is designed to tackle a 130W TDP thermal envelope, the Dynatron G666 2U Xeon server heatsink holds up, very very loudly.
