Does this motherboard have any connections for case fans other than the cpu fan?

Yes i was able to connect 2 case fans and the CPU fan to this motherboard. I cant remember how many are actually able to be connected to this motherboard though

What is the size of the cpu fan i can put on this motherboard?

I do not know I did not use this like that.

Would this motherboard use the graphics a cpu has??

I used the CPU integrated graphics until I bought a video cards a couple months later.
