In testing I am comparing against the Noctua NH-U9B SE2 and the Thermaltake Jing that I previously reviewed. They had very similar results, though the Noctua temperatures can be referenced in our review of the Thermaltake Jing.
The testing methodology is to check temperature at stock speeds (3.3 GHz) both at idle and then after 10 minutes of 100% load. I will then re-run those same tests at a moderate overclock using the MSI OC Genie. This results in about a 25% overclock at 4.19 GHz. For the tests I disabled the fan speed control and ran it at 100%. The Thermaltake Jing and Noctua have been the quietest coolers I have tested, so I will be making a note about noise levels in the conclusion as well.
In the screenshots I have included the CPU-Z results. OC Genie tweaks the core voltage from 1.224 volts to 1.384 and changes the multiplier from x34 (x16 when idle) to x42.
To get a temperature I averaged between the four cores reporting in Core Temp. At stock speeds the Jing had temperatures of 25.5 degrees Celsius at idle and 40.00 degrees Celsius when maxed out.
Overclocking with the MSI OC Genie resulted in temperatures of 31 degrees Celsius at idle and 53.25 degrees Celsius when maxed out. This means there is an 8.25 degree Celsius degree increase at idle and a 13.25 degree Celsius increase when the CPU is maxed out compared to the temperature when maxed out at stock speeds. On the next page we will take a look at the Thermaltake Frio OCK results and see how it compares.
