Testing
After running both the 800 and 1200 RPM versions of the Noctua NF-S12 120mm fans through our ghetto static pressure tester, we can see that they didn't fare very well. Please bear in mind that although the chart shows 0 cm/H2O of static pressure, it does in fact fall somewhere between 0 and 0.099 cm/H2O.
Now this is looking better...the new Noctua NF-P12 shows a marked improvement in static pressure. Once again the static pressure shows 0.1 cm/H2O on our chart, but in reality would fall somewhere between 0.1 and 0.199 cm/H2O.
We can see the increase in air flow of the Noctua NF-P12 over the older NF-S12 series.
And again once we try and measure the air flow through the radiator, the NF-P12 is the only fan that has enough static pressure to force the air through the radiator fins to register air flow on the Anemometer.
Utilising both the NF-S12 and NF-P12 120mm fans on the radiator for our cooling tests yielded some interesting results. I have included some Scythe S-FLEX results in the chart to help make a comparison. The NF-S12 800 gets left behind at 7v, but the NF-P12 performs better than the Scythe S-FLEX's thanks to its increased static pressure. The NF-P12 certainly has the goods and it performs well whilst being almost totally quiet. Excellent effort Noctua!

Brilliant work PV as usual 
No, thank you mate. I've only added the info that we couldn't get done for your review. But I'm glad you liked it I'll put a link in your review now as I'm about to head off to bed.
