LOL, yup

At 4mm H20 static pressure it is still putting out about 190CFM. As a point of comparison, a Y.S. Tech 120mmx38mm 3000RPM fan has already dropped to 1/3rd of it's zero pressure rating.
But that monster of yours has a 59dBa noise level. In comparison the high end Delta 80mm is "only" 52dBa. You better not only have ear muffs, but lots of room too, lol.
