we're sorry to hear about the noise and vibration concern being reported when the fan is running and would love to assist. Please review our article here to assist https://www.samsung.com/us/support/troubleshooting/TSG01001942/. We do like to advise the fans are not completely silent, but they are generally quiet. If a fan is making an abnormal sound (such as squealing, grinding, or squeaking, especially when it stops or starts), visit https://www.samsung.com/us/support/service/ to request a service repair.
