I'm going to recommend the Arctic Cooler Freezer A30 mostly due to the review of the I30 (Intel unit) found here http://www.bit-tech.net/hardware/2012/04/03/arctic-freezer-i30-review/3
Hope it helps
Also I just searched its dimensions and i am not sure if it will fit in my case i have a atx mid-tower
dimensions of it are 18 x 8 x 19 LxWxH
but i will also lose some width because of the mother board.
