Advanced users • 4-pin GPIO PWM Fan Connect To rpi4

i have a PC fan of foxconn nearly the size of the pi itself... i have been using this as a normal pi fan just makeshifted and adjusted it to put it on the pi

it really does the job well... it has 4-pin outlet as shown in the attachment till now i was powering it with 12-v power supply externally (not connect to pi but it sat on it)
i was not satisfied by this because i was not able to control the speed of the fan as i have overclocked my pi
i will keep powering the fan externally, i just wanted to know that how would i connect PWM wire and Tach wire to the GPIO pins on the pi to control the speed of the fan. and also wanted to know that what i have to change in the Boot config things or whatever...

BTW, I am using DietPi (so, please tell according to that) (and i am also very new to this all things so please help me )
Please give me some suggestions.

Thank you. Sorry for bad english
