So after 5 hrs, my "overclocked" cub has climbed to 33.9 gh/s (87.21% efficiency), while my standard/low clocked cube is operating at 31.6 gh/s (96.14% efficiency).

Huh

Any idea why it won't get anywhere near the 38 gh/s?? voltages all test out correctly too. Can Cubes be too cold? the outer case is cold, and the air exiting it is pretty cool as well (feeding it freezing air from a window).

I'm also unable to break 95% efficiency on the cube, any tips??

Take it out of its case and put another fan on it. I run over 38.2gh/s on both of my 2 cubes.

The air exiting the Cube is already cold... what would adding more airflow do? The cube already feels like a cold plate. It's 36F ambient outside, from which the air blown at my Cubes are from. I don't think heat is an issue. (yes, all the heatsinks have been property tightened).
