Your Tower fan, depending upon which brand you purchased, shouldn’t be noisy no. Some are entirely without noise whereas others emit a low noise, like white noise, that some people find soothing and relaxing as it helps to minimize other external noises which can be distracting. Most of the Tower fans more commonly available will emit around 60-70 decibels so check the reported output first before investing. Just to put that into perspective, a whisper measures in at 20 decibels and a library at 40 decibels so really an average fan is pretty low on the disturbing noise front!\r
