Why don't they provide the backplate? One reviewer on that link bought the cooler and forgot to order the backplate. Makes no sense to buy a product that states LGA 1156 compatible but yet it comes w/o the most important part.
I never understood why manufacturers are taking so long to release affordable coolers for the 1156 socket. One would think that they would be in-stock before the mobo's came out....
I agree, if a heatsink lists sockets it covers all the necessary pieces of the puzzle should be packaged with the heatsink, you should not have to purchase anything separately.
