How many cfm, or cubic feet per minute?

Google says "120,2 cubic meters per hour to cubic feet per minute = 70,747049 (cubic feet) per minute." I can type that in with the best of them.

Is this an airflow fan or a static pressure fan?

The fan blades are shaped for static pressure. https://www.amazon.com/dp/B00KF7PPY4/ref=psdc_11036291_t1_B07CG2PGY6 are shaped for airflow. These are static optimized fans

If I want to only use two wires on this fan for max speed, which leads should I use green / black ?

Here's some info that might help you, and should answer that question giving you some confidence... that extra pin on a 4 pin fan is the digital speed control -- this is why the fan goes at max speed if plugged into a 3 pin connector (letting the 4th pin just hang over the side), rather than a a 4 pin connector. Pin number 3 is what tells your motherboard the rotations per minute (RPM) of the fan. So, all that you are left with is the first two pins. The first pin is ground (almost always black) and the second pin is the power (it's 12 volts, but you can get 5 volts from the a custom connector from the power supply instead of the 4 pin motherboard connector if you want to have a slower fan). Here's a chart: For 4-Wire Pulse Width Modulation (PWM) Controlled Fans Pin Name Description Wire color(usual) 1 GND Ground black 2 +12V Fan Power yellow 3 SIGNAL Fan RPM green 4 PWM Digital Control blue So to answer your question, yes it is possible to just use the first two pins (regardless of color, although the first one is almost always black, but the color of the second one is not always the same).

Will the pwm control on this fan stop it completely even with power to +12v/gnd?

On my motherboard (ASUS X99-E WS), can't speak for any other motherboards, any percentage below 50% results in no movement, giving you only really adjustment between 50-100%. I found this somewhat frustrating, but I do prefer this to them never coming to a complete stop.

風量がありますので助かっております！！

高回転だと結構うるさくなりますが、風量がありますので助かっております！！

騒音が静かです

以前使用していたケースファンはメーカー不明ですが、うるさく感じた為買い替えました最大回転数の騒音を比較し、体感ですが明らかに静かでした！満足しています光る機能は無いですが、機能性重視の方にオススメです

簡易水冷の吸引ファンとして

iCUE H150i RGBの付属ファンと交換しました。静音性が高くなりつつ冷えてます。グレーで落ち着いた音で流石です。

とにかく安定している

静かで安定して稼働しています。グレー色のため、PCケース内部が見えるユーザーはそこだけ注意です。

防振ゴムは別売り

四隅の防振カラーゴムは別売りでした。付属かと勘違いしていましたので購入を検討されている方はご注意ください。

えー、正直買いです

パソコンパーツを新しく買い替えたこともあり、排熱が心配になったため既存のケースに付いていたファンに追加するために購入しました。グラボは3080ti、CPUも新しくCore i9 12900Kにしましたが静音性も素晴らしく排熱も問題ない状態です。今後ケースの全てのファンをこちらに交換する予定です。

直進性の高いファン

内排気グラボだと、グラボの排熱をCPUクーラーが吸う問題があります。いくらかは吸うかもしれませんが、高い風圧（静圧）でCPUクーラーとグラボの間を通過させてリアに排気させる力業で、NF-F12 IPPC2000とNF-P12 redux1700の2種類購入しました。IPPC2000の方は静圧121.8㎥/hとredux1700より若干静圧も高く、2000回転と期待していましたが、低〜中回転数域においての直進性が低いです。対してredux1700は静圧120.2㎥/hとIPPC2000より若干低く最高回転数も300rpm低くあまり期待していませんでしたが良い意味で裏切られました。低回転時でもしっかりとケース後部まで風が届きます。直進性の高いファンなのでフロントファンにオススメです。IPPC2000や3000ファンは静音とはかけ離れているので、あまりうるさくしたくないが静圧重視ならCPUクーラーや水冷ラジエーターファン等にもオススメです。NH-U12A等のCPUクーラーにも付いているNF-A12と比べてもNF-P12redux1700の方が上です。はっきり言ってredux1700と比べるとNF-A12なんて全然使えません。それぐらいのレベル。ちなみに排気ファンはNF-A14 IPPC3000PWMで排気しています。
