The Inq writes the ATI R600 graphics card will feature a new less noisy cooler:
ATI sort of listens to the market and so it plans to redesign the R600 cooler. We don't yet have details how this new stuff is supposed to look like but if you know that R600 should be the biggest and warmest chip ever, we expect a very efficient cooler.
It has to be better from the current R580 cooler as the present one has reached its limits with the current hardware. The upcoming one will just get hotter.
