Fan noise

Depending on where it is.. You can mount inside the tent if you have space to make it quieter.. You can put it in a box and cover the box with blankets. Just check on it in a few hours to make sure it doesn't get too hot. Ear plugs are awesome too. You can also just try the ole get use to it method ha ha. Eventually your brain will learn to drown out the noise..... eventually being a key word there.

If you hang it with ropes or something the ropes will normally take most of the the vibration noise... I built a small wooden box for mine and hung it inside that.. Seems to have quietened it down some bit
