Testing Methodology

For our testing we will be using the following procedures and parameters to acquire the necessary data:

• Thermal compound used is Arctic Silver 5
• Idle temperatures are recorded after the system has been allowed to idle for thirty minutes from the point Windows has finished loading.
• Load temperatures are recorded by running OCCT for twenty minutes on all available threads.
• Real Temp is used for the recording of all temperature sensor reading.
• PWM function is disabled via BIOS to allow the fans to run at full speed.
• CPU model and overclock speed used for testing are outlined below in "Test Hardware".
• Each cooler is first tested with one fan supplied from the manufacturer.
• Each cooler is then tested again with a second fan attached if provided by the manufacturer.
