you're running a belt driven compressor of course it's going to make noise. can you elaborate more of what the noise is from? did you check your bypass valve? maybe that is making the noise because it's too loose. does yours sound anything like this?

What was that constant knocking noise in that vid?

it sure does sound like a engine knock of some sort but it's not. it's the bypass valve that's fluttering during idle.
