Testing on larger heatsinks are done on our
LGA1366 heatsink testing platform, while smaller coolers like this CoolerMaster tackle our LGA1155 heatsink testing platform. A summary of the test system
and procedure follows.
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 LGA1366 CPU heavily, generating more heat than most real applications.
8 instances are used to ensure that all 4 cores (with Hyper-threading) are
stressed.
- 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 the lab's variable DC
power supply while the rest of the system was off to ensure that system noise
did not skew the measurements.
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.
