HIS has been working on a new cooler for the pretty hot Radeon HD 4850 and 4870 products. They are almost ready with the ICEQ4 model. The new ICEQ4 model has a two copper heatpipes based cooling system. As always the design is dual-slot (two slots) even features gold plated DVI connectors.
HIS expects the products to the market in August. Would be great to see some custom 3rd party cooled Radeon HD 4000 series products. This by the way is the Radeon HD 4850.
