Korean company Zalman, known more for its innovative PC air cooling solutions, PSUs, and cases, entered the graphics card business. The company is now an AMD Radeon add-in board (AIB) partner, and started its lineup off with some upper-mainstream models. It makes perfect sense for Zalman to enter this business, as it holds some expertise with high-end graphics card cooling solutions. Zalman can source PCBs from any of the major foundries such as PC Partner, Hightech Information Systems, or TUL, and assemble its coolers on top of them. Zalman's first three graphics cards are based on Radeon HD 6870, HD 6850, and HD 6770, with AMD reference clock speeds. What markets Zalman will target its new graphics card lineup with, is not known.
