Heatsink testing methodology

  • Each heatsink test consists of two parts, Real Test and Synthetic Test.
  • Real Testing is performed in a real system, while Synthetic is done using methods that simulate thermal loads.
  • Stable thermal loads are used in order to have accurate results, more specifically thermal load is produced by power resistors.
  • The thermal load wattage is 30,60,90,120,150,180,210 watts. This covers a really wide range of processors and also overclocked states at wattages of 180 and 210 watts.
  • Temp readings are taken from a sensor inside a copper plate that is the exact size of the processor tested in order to simulate the cpu with the best way.
  • For reading the temperature I am using a high sensitivity digital multimeter.
  • Thermal paste used in each test is Noctua NT-H1 because it has very quick break-in time.
  • The copper piece that simulates the processor is not perfectly sanded, because the actual processor heatspreaders are never mirror polished.This happens again to have as accurate results as possible.
  • Sound pressure levels are measured with a high sensitivity digital sound pressure meter, from 20cm away of the cooler inside a sound proof box to eliminate any external noise of echo.


In order to have more clear results Arctic Cooling Freezer 11 LP will be compared with:

  1. Intel Stock cooler
  2. Nexus H.O.C. 9000


TESTING PART 1 - Real Testing


System used for the test







TESTING PART 2 - Synthetic Testing

Stable thermal loads are used in order to test the cooler at a wide variety of thermal loads, this test simulates cpu states from Idle to Overclocking




TESTING PART 3 - Sound Pressure Level

Intel Stock cooler is probably one the most silent coolers in the market. According to noise everything under 17-18dBA is considered to be innaudible, while noise over 50dBA is annoying for me and most people.
