Hello,
I'm trying to make a DIY Wind simulation setup but I have absolutely no prior experience with Arduinos and electric circuits and I'm a little confused.
So the datasheet for the 2 fans that I'll be using is below:

I also bought an Arduino Uno R3, an Arduino Motor Shield, and a 12V 2A power supply.
The fans have 4 pins and I'm a little bit lost on how to connect them to the Arduino or the Motor Shield. Any help would be appreciated.
Edit: The link has been removed. The fans are "Arctic P12 Max", they have a 4 pin PWM connection.
To connect your Arctic P12 Max fans to the Arduino Uno R3 using the Motor Shield, connect the ground pin of the fan to GND. The VCC pin to the 12V power supply. Tthe PWM control pin to a PWM-capable pin on the Arduino (like pin 9). The he tachometer pin can be left unconnected for basic use. then, use analogWrite() in your code to control the fan speed. slope
