ASUS’s exclusive SilentCool technology deals with the heat generated by the graphics processor and memory. This technology has been implemented in some earlier graphics card models from ASUS to animated applause as well as to deserved criticism. Our tests are going to show how the passive cooling handles a Top-class graphics card and how it differs from the previous versions of the technology. The cooling system works like this:
The SilentCool is a heatsink with a large ribbing area that covers the GPU and memory chips. It also has additional heat-spreading plates fastened on a moving joint. To minimize weight, the heatsink is made of aluminum and the heat-spreader is made of copper; the components are connected via a heat pipe. For better heat transfer, you should turn the joint in such a way that the CPU fan blew at it. It means that the CPU fan cannot be over 11cm tall. If you’ve got a taller one, you may need to provide additional air cooling for the card to prevent overheat.
We made sure the stock cooling system of this card did its job well. The GPU temperature wasn’t higher than 51°C in idle mode and not higher than 72°C under 3DMark05’s load.
Noise, Overclocking and 2D Quality
Lacking a fan, the card is completely noiseless. As for overclocking, the card already comes pre-overclocked and further increase of its frequencies will certainly call for additional cooling, negating the card’s main advantage over its competitors.
Expectably from a device of this class, it provides an immaculate-quality 2D image. At least we could see nothing wrong in 1800x1440@75Hz display mode.
