Anyone tried memory cooling on the 9700 series cards yet? If so, what did you use and were the improvements worthwhile. I basically want to run a 9700 at 9700 Pro clock speeds, the card is a UK Sapphire (red pcb) with Samsung memory. I'm not really thinking of pushing the stock 9700 Pro settings any further but I also want to ensure the card is cooled properly so that it's life isn't shortened too much. Has anyone tried a Zalman heatpipe?
