FrostyTech Mk.II Synthetic Thermal 
            Heatsink Test Results 
             
            Intel 
            Pentium D / Extreme Edition & Quad Core class heatsinks tested 
            at 150W Intel Core 2 Duo / Pentium 4 / 
            Celeron class heatsinks tested at 85W Results based on readings from a 30x30mm copper 
            interface die with 150W and 85W heat loads applied on the LGA775 
            version of the Mk.II 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. |

    | *heatsinks are ranked according to the 150w 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. | 
Intel processors vary in 
power output between single and multi-core models, so FrostyTech tests heatsinks 
with two thermal loads that represent the upper limit of each CPU family. With a 
150W heat load applied by the Intel LGA775 
version of FrostyTech's synthetic thermal test platform, the Glacialtech Igloo 
5710 Plus Silent heatsink is able to maintain a temperature of 30.2°C over 
ambient, with 39.3dBA noise. 
An 85W 
heat load applied was applied next, and under this test environment the Glacialtech Igloo 5710 Plus Silent heatsink kept 
temperatures to 18.5°C over ambient. 
In terms 
of thermal performance, the Intel CPU die test is a true representation of the 
capabilities of the Glacialtech Igloo 5710 Plus Silent heatsink. Because the 
Intel CPU die is smaller than the base of the heatsink, full contact is made and 
the raised edges do not interfere. 
On the 
whole the Glacialtech Igloo 5710 Plus Silent performs about average on the Intel 
reference chart, and would in all other respects be suitable for workstation PC. 
However, because of the poor attention to base flatness on the Igloo 5710 
Plus Silent heatsink that Frostytech tested, we recommend avoiding this model 
altogether. Not recommended.
