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.
