Temps and power consumption
The massive Arctic Cooling heatsink comes into its own in the temperature tests, beating the reference GTX 480 heatsink by a whopping 31°C in the real-world Crysis test. The reference card's fan needs to spin-up significantly to keep the card from hitting 100°C in the taxing FurMark test, to the tune of an ear-splitting 3,500rpm, whereas the KFA's fans spin at a steady 2,500rpm and produces the lowest under-load temps of the lot. Impressive stuff.
The Anarchy consumes a few more watts than the HD 5970 when rendering Crysis. Tap into FurMark and the positions change. Bottom line here is that all high-end combinations - be they single cards or multi-GPU - don't go easy on the PSU. We'd recommend users look towards a quality 750W PSU at a minimum.
