Noctua NF-P12 Static Pressure Performance


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!
