Yes, it works with the 1155's. I built a i7 2600K rig this past weekend using the Megahalem. The back-plate was modified to work with the 1155, as well as the 775,1156, and 1366.
I had two CM Excalibur's lying around and mounted them on; they seem to be working OK. I running the 2600 @4.7 using 1.33 volts and the Prime95 temps are running between 64' and 68'. I read later the Excalibur's don't really excel as heat-sink fans, so I may think about replacing them later.
