mazooni :
Ok. Thanks. I have a Noctua NH-D14 SE2011 that I do not use anymore. Are there any mounting kits I can purchase that would make it compatible with a AM3 Socket so that I can use it on a FX-6300 cpu?
If a mounting kit exist that i don't know, but if you go with the 212 and your notcua has a 120mm square fan on it, you would defenetly be able to re-use this fan on the 212 it comes with plastic clips so you can mount just about any 120mm fans you want on it...you could use both fans and have it in a push pull..
EDIT: Here is what is said on newegg about the noctua NH-D14
Compatibility
Intel LGA1366 / 1156 / 1155 / 775
AMD Socket AM2 / AM2+ / AM3 / AM3+ (backplate required)
So yes there should be a backplate to mount it for AMD board, is it exactly this one that you have?

EDIT 2 (LOL)
It is said on another website that the noctua NH-D14 use the standard AMD backplate, would you check in your motherboard box if you would have this plate? there should be one...i think you should be able to just bolt that thing onto your new mobo man...
EDIT 3: (LOL LOL)
I think it should look something like that :
