http://www.hexus.net/content/item.php?item=5158This heatpipe seems to move heat from appromately 2cm away from the GPU die, and transfer it to a location... 2cm at the other side of the GPU die, give or take a few millimetres. It's a PCIe card too, so there's no bridge chip under the lower part of the pipe. There's no mention of the heatpipe in the press release. In that case then, given that we can't see how it helps cooling, our guess it's for use as a carry handle.
