Need help with mobo pins and fans

[TichiWTF]

Hi, i'm posting here because I tried to answer to my question by myself but I couldn'd so I need some help.

The question is: What type of pins does the motherboard I'm willing to buy has? ( Gygabyte ga ab350 )

Because I have ordered a set of fans ( corsair air series af120 ) that have a 3pin connector. I know that you can connect a 3pin connector to a 4pin header or a 4pin connector to a 3pin header but i want to know if my motherboard supports pwm or voltage control ( the last one is pretty important because i want to control the fans )

Anyway, thank you for your time and I hope I made myself clear.

There are 5 fan headers: cpu_fan/opt, and sys_fan1/2/3. They're all 4pin headers and support a pwm/dc mode. You can find this info in the motherboard manual. http://www.gigabyte.us/Motherboard/GA-AB350-Gaming-3-rev-10#support-manual

That being said, their recent generations of motherboards have had more limited fan control options in the bios and you might have to use their SIV software in Windows instead.
