It has been widely mentioned in reviews and by users themselves that ATI's HD 4800 series cards can get pretty toasty when used on stock cooling (largely down to issues with fan speed settings). Diamond's latest 4800 series cards should have no such issues, seeing as they ship equipped with water cooling blocks courtesy of Danger Den. HD 4850, HD 4870 and HD 4870 X2 cards under Neptune Edition branding are available in the line up, with each coming overclocked out of the box (though what those speeds will be aren't specified). Apart from the improved cooling, Diamond has also been tweaking with the firmware on the cards which it claims will allow users to push beyond normal overclocked speeds for extra performance. All three of the Neptune Edition cards should be available through System Builder Smoothcreations, NCIX, TigerDirect and Newegg starting today.
