Thanks for your reply, but I don’t believe it’s foam or debris, doesn’t sound like same.

I tried playing around, adjusting the settings to localize the problem and I realized that when the red / blue thumb wheels by the center vents are fully red, I don’t hear the noise, but when they’re centered between red and blue, the noise resurfaces.

Not sure what that indicates, however. :|
