I have already bought a case that supports 4 fans and has 3 pre-installed fans in it

I'm not sure how many fans my motherboard supports and I might not be able to use the full potential of all 3 fans that came with it, and a spare fan I have lying around.

I'm not sure how many pins a fan needs and if the motherboard I am thinking of getting will be able to power them all. Will it be okay? If not, what motherboard do you suggest me getting? I use CAD, not USD and my budget is under $400, preferably $350. This is the current build I was thinking of :

If it doesn't reach over $400, it should be fine.

I'd also like to know if all fans are 4 pin or not. I'm still fairly new to pc building and have done at least 2 hour of research every day for the past month or so. I'd like some nawledge from some more experienced people.

The 3x 120mm stock fans you'll get with your Rosewill case are most likely DC controlled fans and either a 3-pin or 2-pin fans. DC fans need only 2 pins to work, the +12V and ground. The 3rd pin on DC fan is meant to send RPM data back to the MoBo for BIOS and/or software to read it but it isn't vital for normal operation of the fan itself.
As far as stock fans go, i have yet to see a case that comes with stock 4-pin PWM fans.

The MoBo you're planning to go with has 1x CPU fan header (4-pin), 1x case fan header (4-pin) and 1x power fan header (3-pin). Since CPU fan header is needed for CPU cooling, it leaves you 2x fan headers for your case fans.
Your MoBo manual, page 18 covers the fan headers pinout,

Commonly, the standard case fan header supports 1 A at 12V, while power fan headers have higher amperage support at 12V. How much your MoBo power fan header actually can support, that i don't know since it isn't written in MoBo manual. While most fans operate under the 0.5A at 12V, you can connect 2 fans to one single MoBo fan header without issues. To do that, you'll need to use the Y-spiltter,

You'll need 2 of such connectors to connect two of your case fans into one single MoBo fan header. That solves your fan connection issue since with 2x fan headers and 2x Y-splitters, you can connect all your 4x case fans to your MoBo.
