According to a flash banner on the Sapphire's Atomic Web site, the Atomic version of the Radeon HD 3850 will end up with Zerotherm cooling. This one isn't strange if you know that Zerotherm is listed as one of the partners on the Atomic Web site.
As you can see from the pictures below, the Atomic HD 3850 will use some kind of variation of the APACK Zerotherm Hurricane HC92 Cu 8800. We said variation because the current HC92 Cu 8800 doesn't support HD 3850 cards, at least not according to the specs on Zerotherm's web site. Inno3D has used this cooler to cool down the 8800GT so this cooler will definitely do a great job with the HD 3850.
Zerotherm's HC92 Cu 8800 has four pure copper heatpipes and a 92mm fan. It also comes with fan speed control via a small bundled fan speed controller. Will the Atomic HD 3850 use the same H92 CU 8800 or a variation of the same, if this will take a toll on cooler specifications it is still unknown, but time will tell what the final solution will be.
