Larger heatsinks are tested on our LGA1366 heatsink testing platform, while smaller coolers tackle our LGA1155 heatsink testing platform. A summary of the test system and procedure follows.

Key Components in LGA1366 Heatsink Test Platform:

Key Components in LGA1155 Heatsink Test Platform:

The systems are silent under the test conditions, except for the CPU cooling fan(s).

Normally, our reference fans are used whenever possible, the measured details of which are shown below.

Measurement and Analysis Tools

  • Extech 380803 AC power analyzer / data logger for measuring AC system power.
  • Custom-built, four-channel variable DC power supply, used to regulate the fan speed during the test.
  • PC-based spectrum analyzer: SpectraPlus with ACO Pacific mic and M-Audio digital audio interfaces.
  • Anechoic chamber with ambient level of 11 dBA or lower
  • Various other tools for testing fans, as documented in our standard fan testing methodology.
  • SpeedFan, used to monitor the on-chip thermal sensors. The sensors are not calibrated, so results are not universally applicable. The hottest core reading is used.
  • Prime95, used to stress the CPU heavily, generating more heat than most real applications. All instances are used to ensure full stress.
  • CPU-Z, used to monitor the CPU speed to determine when overheating occurs.
  • Thermometers to measure the air temperature around the test platform and near the intake of the heatsink fan.

Noise measurements are made with the fans powered from a separate, fanless system. Load testing was accomplished using Prime95 to stress the processor, and the graph function in SpeedFan was used to ensure that the load temperature is stable for at least ten minutes. The temperature recorded is the highest single core reading. The stock fans were tested at various voltages to represent a good cross-section of airflow and noise performance.

The ambient conditions during testing were 10~11 dBA and 21~23°C.
