From our usual source of information, third party heatsink makers might not be able to ship their heatsinks in time for the launch of Sandy bridge E.
As the new processors has a larger footprint and occupies almost 1/4 of the motherboard, heatsink manufacturers have to factor in design considerations to ensure that it doesn’t block the surrounding DIMM slots and other peripherals.
Although these heatsinks might be in shortage, the OEM heatsinks should be sufficient to handle the heat dissipation from the Sandy bridge operating at room temperatures.
We are also aware that some designs of motherboards might be able to adapt older generation of heatsinks, perhaps with 2 sets of mounting screws on the PCB.
So if you intend to do some overclocking, you might have to hang on a while for the better heatsink to go retail.
