TPU noticed Yeston has created a new Radeon HD 7970 design that incorporates a massive dual-fan cooler. Exact details aren't available, but it looks like the company is using 120mm impeller-style fans with 18 blades, and that the bundle takes up four expansion slots.
Underneath the frame holding the two fans is a large aluminum fin stack-type heatsink that spans almost the entire area of the PCB. A copper base makes contact with the GPU, from it, six copper heat pipes originate, conveying heat to two aluminum fin stacks, which are then ventilated by the two fans. When fully assembled, the cooler is so large that it appears to span across almost four expansion slots. Yeston is reportedly still working on improving the design. Let's hope it gets a lot slimmer than that.
