Need some help (mid build)

post #1 of 5
Thread Starter 
Your help would be hugely appreciated.

1) I've got a Fractal Midi Arc 2 with 3 case fans, but only 2 3-pin fan connectors on my motherboard. Can I plug the fan into a 4 pin connector (it fits)? Or how should I fix tihs.

2) my motherboard's input-output shield had these terrible metal bits next to the inputs. As the ignorant computer builder I am I removed some of them. I spoke with a computer-builder friend and he said I'm fine. Is it alright? I hear they help "ground" the input-ouput shield. I kept maybe 20% of them on, so there is some grounding. Not even going to use the shield anyway---got my own video card, wireless, etc.

THANK YOU

1. Yes you can plug a three pin into a four-pin header. Also the opposite works, as long as it fits.

2. Nope you should be fine. The whole motherboard is grounded to your case anyways. If we needed the I/O shield to be on for the computer to work then scratch builds wouldn't be so fun, would they?

I have an integrated fan control with this case. I'm not sure how to set it up. I've also read that putting a 3 pin in a 4pin messes with that.
