The CPU fan plug is meant to control a fan for your CPU cooler. You should be using that one for your cooler.

The Sys fan plug is meant to control a fan that blows air to cool your motherboard.

Your CPU fan will go faster if the motherboard detects that your CPU is getting hotter. So when you plug it into the CPU fan plug, it will be going faster than the Sys fan plug, thus being louder.
