PWM Controller for 120mm fan S4

[krivis]

Hi guys,
please help me with my fan that i pulled from the mining machine Antminer S4.
So the fan is working in the Antminer but i can not start him with external power 12V5A and external PWM controller that i bought from ebay. I tried every possible wire connection but nothing happens. Once just spinned only one circle . I dont know the pinouts but here are the specs from this fan.

You need a logic level PWM driver.

Can i build one? Can you please point me to some schematics for that logic level PWM driver?
