Product review (4 stars): cool little item
noise level: right now it is 3 feet from my bed so I hear it! it doesn't keep me from falling asleep or waking me up but I hear it.

cold level: I have it at a 5 and half out of 7 and its holding at 45 degrees at the class so it would be a little better in the back.

downside: there really isn't one. the noise level maybe a little more silent would be nice I have some sound absorbing foam behind it to try catch some of the noise since it is right next to my bed but other then that its cool item
