As shown on the picture above, we see the following:
• The NF-S12 generates less noise than the NF-P12, especially at low speeds. At 1100rpm and above, the difference gets smaller. • The NF-P12 produces more airflow than the NF-S12 at 1100 rpm and higher, and the other way round at 1000 rpm and less. • The NF-P12 produces a bigger static pressure at all speeds.
While the NF-S12 delivers less static pressure, it delivers a better airflow/noise ratio at lower speeds. Therefore it’s perfect as a case fan where a high static pressure isn’t required, but a low noise level is. As a result the NF-P12 should be the first choice when running at 1200+ rpm, and also when using units that requires a high static pressure.
The test: I’ve chosen to compare the fan with one of Noctua’s older products, the NF-S12-1200 which is mounted on a Thermalright Ultra-120 cooling a Q6600 Kentsfield 2.4 GHz. As many of you probably know, this kind of CPU gets pretty hot. It will be tested in a very well organized Zalman Z-Machine GT1000 case, which has 2x 80mm fans in the front and a 120mm at the back.
I started off by reading the temperatures with my current NF-S12-1200
Conclusion: As you can see the cooler performs the best at full speed, which is at 1300rpm and that makes perfect sense. When talking about noise level, I must admit that when I sit in front of my screen, I can’t hear any difference in the noise levels, only if I move closer. If you compare the “old” NF-S12-1200 model with the NF-P12, the NF-P12 performs worse which is disappointing. With that said, I still think it’s a great cooler when comparing it to the standard cooler that came bundled with the CPU, that cooled about 8-10 degrees worse and made a lot more noise.
The fan price will be around 150kr, which some people might find a bit pricy, but some say you get what you pay for, and I think this fan lives up to that standard, although I doubt that people will spend that amount of money on a fan.
Moves a lot of air Mounting possibilities Low noise Nice and different design (depends on each persons taste) 6 year warranty!
