for modest overclocking and if the cost is the same (C$75) which of these 2 is best in terms of:
a. cooling performance (cooling/lowering the most degrees Celsius)
b. noise level.
c. with how low rpm?

Would the airflow with 2 fans be the 140mm pushing towards the tubing while the 120mm pulls away from the tubing?? In other words both fans moving airflow in the same direction?

Thank you

The U14S is quieter, without a doubt. And it performs excellent. I use the NH-U14S on a FX-8320 overclocked to 4.5Ghz, on a 990FX Sabertooth board, which is a full Ghz overclock, and I have great temps, no issues. The only time I even hear the PSU fan is after it's been at full load for longer than 30 sec and even then it's not bad. And chances are you'll rarely have the CPU at full load on all cores for long periods of time unless you're stress testing or running some serious apps. In which case, you'll expect there to be some noise. It's also physically smaller than the D14, so that's a plus.
