- Summary and product highlights
To test the CPU cooling units we use the der8auer-Test-Bench. It has been modified with a Intel Core i7 4770K Heatspreader on the contact surface. The contact surface itself has been cut down to the shape of a 4770K DIE. This will make sure that the test bench creates heat load similar to a normal CPU and the results are equal to a normal test.
We use the Thermal Grizzly Kryonaut thermal paste for all coolers to make sure the thermal paste is not limiting the test results.
Each cooler is mounted 3 times and we measure the temperature difference between the ambient temperature and the temperature of the heat-base. This means that a lower temperature-difference (dT) equals a better performance.
In addition we measure the sound-level of all coolers in 30 cm distance.
All tests are done at 3 different fan speeds. 5 Volt, 7 Volt and 12 Volt.
The Test Bench can be adjusted from 40- 240 Watt in 40 Watt steps. Depending on the heat load you can apply the test results to different scenarios:
- 40 Watt: HTPC / Office PC
- 80 Watt: Gaming PCs
- 120 Watt: Moderate Overclocking
- 160 Watt: Overclocking
- 240 Watt: Strong Overclocking
