    [Misc] Exhaust fan noise

    Customers have recently complained about Sharp MX-4140's fan noise being louder than previous models. I noticed the LSU intake fan has a small aperture that the fan forces air into since it's quiet as hell when I pull it out. Has anyone else had complaints and/or discover any reasons for this?
    Also, MX-2640's have a louder whining noise then the MX-2610's when the polygon motor is running. Anyone else come across this one?

    Haven't had complaints about the fans but the polygon motors are louder. Sharp had bearing style polygons then switched to air ride bearing style. The last training I was at they said they went back to bearings again.
