A/C is loud

2006 Acura MDX with 91K miles on it. A/C blows cold and seems to work it’s just loud when you turn up the fan speed. It’s so loud anyone that rides with me mentions it. I’ve looked in ducts on don’t see anything obvious that it could be. Makes a roaring sound like something is stuck or maybe a bearing somewhere needs lubricating. Not good at describing noises, any ideas? thanks in advance

If you turn the AC off does the fan make the same noise. In other words is the noise from the fan or the AC (as you state it) ?
