AMA Orc Review



Testing the AMA Orc heat sink is gone about by first installing the heat sink onto the LGA 1366 MSI X58 Platinum with the proper brackets and included thermal paste. Once installation is complete, the system is tested twice for both idle and loaded temperatures in Vista Ultimate 64-bit. The first test is at stock processor speed with no turbo or power saving features, and for load, Prime95 with small FFT's is used. Next the system is lightly overclocked to 166 BCLK causing the processor to run at an effective 3.33GHz. Idle and load temperatures are then recorded for the overclocked run. CPU voltage is keyed in at around 1.25V, and the testing is done inside a computer case with decent but common airflow. The average of the core temperatures is used in the graphs. Ambient temperature is kept around 75F with the temperature during this test at 74F. Once testing is complete the results are compared to other heat sinks that were tested.

Comparison Heat sinks:







The AMA Orc idled higher than all of the other heat sinks. For heat pipe systems to work efficiently, the heat pipes must move heat away quickly - so depending on the coolant used in the pipes, they may start pumping heat away more efficiently at a higher temperature. At load the Orc was second worst at stock speeds, but passed the Gelid SS by far in the overclocked results. No matter what, the AMA Orc beat the stock Intel heat sink in loading.
