The hardware is being pushed to its limits when Prime 95, Furmark and EVEREST is running. After an hour, all temperatures is stable and ready to write down. The room temperature is then subtracted from the measured temperature to show the delta value.
The thermometer is always placed in the middle of the case, around the graphics card.
• To compare the cooling performance of cases, Tweak uses a delta value comparison. The room temperature is an important factor, as an increase of 5 degrees would increase the system temperature by 5 degrees as well. The delta value is therefore the best way to show the cooling performance, all year around.
• The load temperature is reached by stressing the graphics card and processor with Prime 95 and Furmark. Furthermore EVEREST is used to stress the hard drive. The load temperature is measured after one hour of benching. The room temperature is measured at this time, and subtracted from the load and idle temperature, resulting in the delta temperature.
• Temperature measurements of the PC's components is done with HWMonitor from CPUID, while graphics card temperatures is measured with Furmark.
• All BIOS energy saving features is disabled, and the CPU cooler is running at maximum RPM. The graphics card uses a passive heatsink.
