TESTING

System Configuration:

Measurement and Analysis Tools

  • CPUBurn K7 processor stress software.
  • FurMark stability test to stress the integrated GPU.
  • GPU-Z to monitor GPU temperatures and fan speed.
  • SpeedFan to monitor system temperatures and fan speeds.
  • Seasonic Power Angel AC power meter, used to measure the power consumption of the system.

System temperatures and noise levels were recorded with SpeedFan and GPU-Z (if possible) at idle and on load using 4 instances of CPUBurn K7 to stress the CPU and FurMark with the Xtreme Burn option (if possible) to stress the GPU.

Baseline Noise

Noise measurements were made of the case with the rear, top and one of the front fans supplied at standard switch settings in various configurations. The air cavity resonances inside a case amplify fan noise, as do any vibrations transferred from the fans into the case, so these measurements can be regarded as the baseline SPL levels for the Twelve Hundred with the stock fans.

Quality control might be a problem for these fans as we determined that 3 of the 6 included were either defective or damaged, possibly during shipping. The upper rear fan made a brushing type sound like something soft was rubbing up against the motor, the upper front fan had a slight hum, and the lower front fan had a rattle. The other three fans did not exhibit these sounds so we assume they are the norm.

The one good rear fan is fairly innocuous sounding with a mostly broadband acoustic profile when set to Low. The top 200 mm fan is no louder than either of the rear ones, except at High speed. It also produces an audible clicking sound at closer proximity which is masked by turbulence when the fan speed is cranked up. Both the top and rear fans have 3-speed switches accessible from the back of the case, but they can only be described as quiet when set to Low.

All the hard drive cages have their own front intake fan, each with a variable speed controller knob at the front. The front fans are enclosed by the hard drive cages and impeded by the front filters, resulting in a mostly turbulent noise profile, even at minimum speed. They also have a much greater impact on the overall system noise level due to their shorter distance from the mic.
