Mine has the top hole 3/4 covered by a piece of plywood stapled from the inside. I understand what this is for, but to go into mine from top i need to remove the baffel. It Might be hard to secure it again
But I have gotten used to it. Just finishing 2 weeks at beach and don't hear it anymore.
Mine was too actually, partially blocked upper vent. I removed that and replaced it with a shorter length of HDPE plastic sheet, 1/16th inch thick that just comes up to the bottom edge of the replacement fans.
Mine really blows.... (pun intended)...
