my mobo:gigabyte GA-H61M-DS2 (rev. 3.0)

i got problem when installing system fan and usb

first,my system fan cable cant plugged to my mobo,because the cable hole for my preinstalled fan so big,so how to fix this?

seconde,my usb also got into problem....my mobo only support front usb 2.0 and my case usb is 3.0,so how to fix this?

beside that i want to ask,can i install my case fan to my psu using molex cable from psu?
