If that is so then in theory that noise will be around 44dB at 1m according to the inverse square law. In practice I'd expect it to be higher than this in a boxed in room so maybe around 50dB at 1m. Thats not a lot but around about the sound of rain and if continuous may be annoying You should measure the noise at 1m and let us know,Haha that is from 1 inch away from the top of the case.
