i'm using the fatality cpu cooler atm(just popped off the Tt typhoon yesterday)...no clearance issues on either DFI...SLi or rdx. i've tried 4 boards and 3 cpu's...all in all i'm a bit upset becasue this was the most expensive ram there is locally, but it does as advertized, so no complaints from me. running the 180 divider would been nice tho...
