I think the hole PCD's are the same across the two platforms so you should be fine.
Yes will work fine, you might wanna think about changing the fans on the cooler though ( unless you love noise )
Mine was fine in quiet mode and good cooling.
yeah those fans really do let the whole thing down, can get so much more performance with less noise. seems like most do that though with exception to EK who basically through in some vardar F4's but that's more of a premium AIOC.
