Sapphire has been showing off its new Liquid Metal Cooling graphics card, which uses Gallium to cool the card.

The working prototype, based on an ATI X850XT, was on show at Computex and still needs a lot of development work, but the company said it wanted to show the card in action during the exhibition. Gallium is 65 times more conductive than water, and the pipe was only just warm to the touch, even though it had been running for some hours.

The system on show needed two fans and was pretty noisy, but these are the issues Sapphire is ironing out before the card's launch in the fourth quarter. It takes hot air from the card and fans draw the heat out, keeping a constant ambient temperature.

If liquid metal doesn't attract you, there were also plenty of water cooling systems on show, which will be available in the UK over the coming few months.
