Being consistently loud and annoying are indications that this person doesn't adapt well to his surroundings, especially if everyone around him seems displeased. It may be a sign of poor overall judgement.

It may also be that this person was nervous when you interviewed him, and didn't have the forethought to say "I get loud and annoying when I'm really nervous, it will pass."

My advice: test him out. If he is truly great, and you really need a truly great developer, and the annoying bits don't go away: isolate him from your team, manage him closely, and keep him happy.
