A couple of option dependant on cost. The Corsair H150i Pro 360mm is very solid and very quiet due to the Mag Lev fans though it is a bit on the costly side but high quality all around and great cooling,
Second, the Arctic Freezer II 360mm has just been launched at a really good price and well under a $100. Though it does not have RGB it is just stellar on the cooling front with a much thicker radiator at 38mm versus all others at 28mm. This AIO is well worth a look...
Here is the Tom's review of the 280mm version.
