When we first reviewed the HD6990 we found it to be a phenomenally impressive card. A total powerhouse. However the main issue was, as it is with most of the current range of Radeon cards, heat and noise. The perfect solution to any heat problem is to go from air-cooling to water-cooling. Modern CPU coolers are of such high-quality that water-cooling isn't such a desperately important thing for the heart of our machines, but graphics technology has continued apace and almost outstripped the capabilities of standard air-cooling to keep the cards cool. So water-cooling is ideal for our power-hungry, eye-candy providing behemoths. Enter PowerColor with their take upon the HD6990 with a factory fitted EK Waterblock. A perfect opportunity to get a system built we think.
