After showing to the world its Radeon HD 7970 PCB with all components placed, Yeston disclosed pictures of exactly what it's going to use to cool the beast. Yeston's cooling solution uses two big (probably 120 mm) fans inspired by the design of aircraft turbofans, with 18 blades on its impeller. Such impellers with PC cooling fans aren't new, and have been used in case fans designed by the likes of Cooler Master. However, this could be the first time such fans have been used in a VGA cooler.

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.

Amusing to see such a ginormous heatsink for such a tiny die. Put this on Fermi and it will make more sense.

I think this Yeston would cool better. Bigger heatsink and bigger fans.

Doesn't appear to cover VRM and memory.

on a side-note, CaseLabs orders have risen by 25% since this announcement

DAM, shudder to think the weight that puts on the PCI-E slot, that will sag like hell after a week or 2.

Can you imagine someone with this and a D14? Anyone wanna get in with me on inventing a motherboard backplate?

Slimmer? Who cares?! This looks like this will be real quiet. Plus it screams overclocking...

Who cares if no MB supports 4 slots spacing for Crosffire.
I have your answer: PCIe riser cables! inside a CaseLabs or TJ12.

This ^^

I feel GPU core temps are secondary to proper VRM and assorted power circuitry cooling.

You would think that but the Accelero Xtreme barely cools better than the Zalman VF3000F. The latter of which only totes two smaller fans and is considerably smaller in size, yet manages 95% of the performance of the former while being a good $15 cheaper.
