Which cooler is better

Which is better, the thermalright 120 extreme or the titan amanda in terms of temps and noise, especially since I want to overclock as high as possible at as low as possible air cooled temperatures.

Which is the best trade off, as I know about the TT reputation, but the titan's results are quite impressive. I would like to know which is the best fan for noise vs. airflow to go with the TT if you suggest that cooler too please.

Any input?

Bearing in mind my temps are around 50 idle now, what sort of temps would I see with a 3.6 Ghz + o/c with the TT and what would I get with the titan?

Which would be best for a case with little airflow, as my case is under a desk up against the wall in a warm room.
