I am building my first pc and the case I have ordered will fit 5 120mm fans. It only comes with one so I want to buy 3-4 more fans for it. The mother board is an gigabyte b450m ds3h and only has one fan header. When it comes to fans do I need to get a pwm fan and if so I have seen multiple that say 3 pin motherboard or 4 pin power supply. Are these the type of fans I am looking for or do I need a 4 pin straight to the motherboard?
