The cooler you pick depends on the case, motherboard and the number of ram dimms you have in your dimm-slots. If you've got a moderately spacious mid-tower case with a standard ATX board, you shold be fine as long as you dont use the dimm-slot thats right next to the processor.
Since you have just 2 dimms, and will be placing them in the alternate slots further apart from the processor, You're all set for any basic 120mm width and 160mm tall cpu air cooler.
But is there a lot of difference in performance? Because I can get the 212+ in Mexico, more expensive, but it would be covered by a warranty. But if there is a big difference I'm going to the US soon and I may take the EVO, even though I would not have a proper warranty.
