I have for my dual Westmere and before them Nehalem the Dedicated Noctuas for 1366 - no mounting bracket just mount, screw down and go. Is there one like like for 2011-3 - just a single fan and single tower, and dedicated for 2011-3. The only one i can find that's specific for 2011-3 is the big one dual tower design. I know there's that work with the mounting brackets But i really the once for 1366 and not having to mess with the bracket.
