Would using the stock overhead 775 socket motherboard with Q6600 CPU fit on a 1156 socket motherboard with i5 760 CPU as my H50 I was given didn't have backplate and lots of other bit to mount it! So I will run CPU at default speeds if that fan fits as I don't want to uninstall it as its got those awful spring bolts and push pins. I'm building a game rig atm and plan on keeping the mb, CPU & stock cooler combo for a HTPC so I don't want to uninstall unless it will fit the other mb and i5.
