Thread hijack alert: Could someone either pm me so I don't cause too much of a disturbance or just reply below for me...the definition of static pressure, and what it is good for? Thank you!
So higher CFM and higher Static Pressure with lower dBA if you're worried about sound is best.
Would you want fans with higher static pressure just in general,
or would you want fans with higher static pressure for different tasks like for I'm guessing radiators? Thanks again!
Does the static pressure change along with the RPM? Say the fan has 2.09 inH2O / 520 Pa, is that at a specific RPM? Or is it somewhat the same throughout a certain RPM range?
Arn't Noctua fans suppose to have pretty high static pressure for relatively low noise ratio? Are they pretty good? i hope so cause i ordered one to put on the heatsync im getting
Not sure which fan you ordered. I checked Noctua's PWM fan (NF-F12 PWM) and the spec sheet has it at 1500 RPM with 93.4 mm^3/h of airflow (~55CFM) and 2.61 mm of H20 of static pressure (25 PA).
So to answer your question... Yes; Noctua fans offer good airflow/static pressure to noise ratio. Having said that; I'd take any of the fans listed by bing on his post over the Noctua fan. I own two of the models he lists and either fan, when ran at 1500 rpm is whisper quiet while offering much higher figures in CFM and static pressure... Plus I like knowing that if I ever need to crank the speed up; they have the horsepower to push really hard; whereas the Noctua is maxed out at 1500 rpm.
These are the highest static pressure PWM 120mm fans with 12 volt working voltage that I'm aware of, the current static pressure champion is Servo G1238B12BBZP-00 while the highest CFM is 9CR1212P0G03.

Now, pick your ownpoisonears buster.
Wow thanks guys, but yeah I'd be staying around 1000-2000RPM.. don't want to fry my motherboard
OMG but that fans a so sexy!
The fans in my sig work rather well. I find at minimal (1,550RPMs) they put out a low pitched whine which I grew used to quite quickly. The controller on my Corsair H100 never ramps them up except when I turn the computer on so its always pushing the minimal 71CFM. Because these fans have a separate plug for power, which plugs straight into the PSU you don't have to worry about damage to your mainboard or fan controller. 1 plug goes into the PWM fan controller, the other into the PSU.
