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 Noctua NH-D14  will be compared with:

  1. Intel Stock cooler
  2. Thermalright Ultra 120 eXtreme (with two NF-P12 fans in push-pull)

 

TESTING PART 1 - Real Testing

 

System used for the test

  • CPU:Intel core i7-950 @ 3.6Ghz
  • Mobo:EVGA X58 Sli
  • VGA:Dual MSI GTX 260@ Sli
  • Memory:Adata 6Gb kit
  • HDD: 4x Seagate 500Gb
  • PSU: Seasonic M12D 850w

 

 

 

 

 

 

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
