[8rrowhead]

According to the website:  2

 

1x CPU Fan Header

1x System Fan Header

 

So...  basically you're buying a Fan Hub.

MSI advertises 2 fan headers on that board. Low end motherboards usually have very little when it comes fan connectivity. You can get one of these to connect 2 fans per port.

It'll be in the mobo manual on the product support page.

I bought custom built PC and there are currently 3 system fans and the cpu fan running. how can the 3 system fans be running if there are only 2 fan headers? i know you can also plug them into most other slots but all 3 sys fans are detected as such. i can attach a photo if needed

A splitter that can patch through the information of other fans possibly. Or there are actually more fan headers than msi documented (I doubt it but could be).

follow the fan wires and see where they're plugged in?

 

But according to the website, there are 2 fan headers.

just lookad and it appears that the cpu fan header powers the cpu fan and then splits off to power the 2 front fans while the back fan gets its own header. so yes, they did use a splitter.

So, you can either:

 

1) Verify the fans are low enough power to not fuck with the 1A cap on a header.  (IE:  If they're all ~0.2A each, then 3 fans is fine on a single plug) and get a 3 way splitter.

 

2) Buy a Powered PWM Fan Hub and mount it to the backside of the motherboard tray, and not worry about fan power draw at all.

I have this same board. My issue my case came with 3 pin exhaust fan but there is no option in the bios to change from pwm to DC control. So the fan is just on full power all the time.
