Testing notes

The system used for this review was not one of the standard HEXUS testing platforms.

Instead the Core 2 Quad Q6700 was installed into a system built into a full system chassis and with high-end components, mimicking the kind of configuration it will most typically be used in.

Cooling was provided by a Zalman CNPS9700-LED heatsink and fan, while the chassis was a Silverstone TJ-03 fitted with a single 120mm fan in the front and two 80mm fans in the back.

All four fans were controlled using a drive-bay-mounted fan-controller, not by the motherboard, to allow for full control of fan speeds during testing.

All thermals were measured using Lavalys Everest Ultimate Edition, which allowed for temperatures to be read for all four cores from within the 64-bit version of Windows Vista. SpeedFan also works under Windows Vista x64 but reports considerably lower temperatures than Everest.

Stability testing was carried out by using four instances of Prime95 running Small FFTs - with a maximum temperature of 80C deemed as acceptable.
