I have a Xigmatek Dark Knight Night Hawk II, I really disliked the stock fan, so I replaced it with a Corsair SP120 High Performance Edition(3-pin), I'm planning to put another one, should I? if yes, should it be PWM or 3-pin also? (for Push PWM and Pull 3-pin or 3-pin for both Push and Pull)

Thank you in advance.

It depends on what sort of temperatures you're getting, and whether you are happy with them. If you think your CPU is running a bit hot, or you wish to overclock, adding another fan for push/pull is a good idea.

If you use a PWM, then it must be connected to a PWM connector on the motherboard, which will change its speed depending on the temperature of the entire system, instead of just the CPU. If you use a 3-pin, the fan will always run a maximum speed, and you will have no control over it. A 3-pin will give you the best temperatures because it will always be moving the most air, so if you're looking for performance over noise I would go with another 3-pin.

If you're looking for quieter operation, a PWM will allow you to adjust the...

If you're looking for quieter operation, a PWM will allow you to adjust the speed to suit the noise level you wish.

If you choose the first option, I would recommend the 3-pin in the pull position and the PWM in the push.

Hope this helps
