It's possible, although sleeve bearing fans are typically happier mounted vertically, and fluid-dynamic and ball-bearing fans don't generally care much about orientation. Does it quieten down if you tip it slightly back from vertical?The fan was close to silent initially, but now is quite noisy. It sounds like the fans are rubbing against something.
It looks like I can take it apart, I just wondered if it might be because I have the Pi mounted vertically that the fan is not very happy?
