It's been rumored that Intel would offer a liquid-cooling solution instead of a stock cooler with its new Sandy Bridge-E "extreme" processors, and multiple enthusiast sites have indeed snapped photos of the new cooler on the IDF exhibition floor.
From the photos, we can determine that the RTS2011LC cooler has been created in conjunction with Asetek, which had previously announced it was working on a Sandy Bridge-E liquid-cooling solution. According to Legit Reviews, Intel reps said it's similar to the Corsair Hydro H70 kit that Asetek designed, but that parts were updated, including a 120mm fan. The fan even includes blue LED lights. While designed with the LGA2011 socket, it will also work with Intel's 1155, 1156, and 1366 sockets.
Also shown was the new DX79SI motherboard Intel will offer to pair with the Sandy Bridge-E chips. Based on the X79 chipset, it features three PCI Express 3.0 x16 slots, quad-channel DDR3 memory, a pair of USB 3.0 ports, and the skull graphic that Intel has featured on past high-end mobos. (More details here.)
Hopefully, Intel will provide more info about Sandy Bridge-E as IDF continues, but these parts should at least whet your appetite a bit.
