All the fans ive been looking at are 3 pin connector but my motherboard is a 4 pin, Can i still just plug it into the 4 pin?
Yes, it should. But you might want to look through the BIOS for 3-pin/4-pin fan options. The fourth pin is for extra speedcontrol (PWM I think) of Intels stock HS/F. Try your motherboard manual also. My board has a single 4pin and 2 3 pins, so I'd just put it on one of the 3 pins.
