PC Specialist Cosmos II 15.6″ Notebook Review

Noise, Power Consumption and Temperatures

Noise

The amount of noise produced by any computer is a vital consideration for most buyers, even gamers don’t really want a noisy PC because less noise is always better. We use an acoustic dBA meter held 2 feet behind our test system at idle and under load to get the idle and load noise levels for the system. For idle we allow the system to sit at the Windows desktop, for load we let Unigine Heaven 4.0 and Prime95 to loop together – we take the acoustic measurements 5 minutes into both of these scenarios.

Power Consumption

To test power consumption we measure the total system power draw during idle and load scenarios. For idle we allow the system to sit at the Windows desktop, for load we let Unigine Heaven 4.0 and Prime95 to loop together – we take the power measurements from the “Killawatt” AC power meter 5 minutes into both of these scenarios at the same point.

Temperatures

To test thermal performance we measure average CPU and GPU core temperatures during idle and load scenarios. For idle we allow the system to sit at the Windows desktop, for load we let Unigine Heaven 4.0 and Prime95 to loop together – we take the temperature measurements from within CPUID HWMonitor 5 minutes into both of these scenarios at the same point. For load we take the average of the maximum temperatures, for idle we take the average of the minimum temperatures.
