I have noticed the same problem with my newly purchased 3b1 also. However, the problem has recently gone away. I'm sure it is not because I have got use to it. It really bothered me to the point where I had to compare the sond of my fan to several other 3b1's to make sure everything was okay. Be that as it may, even now if I tap on the fan's grille it causes the fan to run at a noticeably slower speed. After a few minutes the fan returns to it's (I suppose) normal speed. Unless the air leaving your fan is REALY hot, I do not think there is anything wrong with your machine. However if your machine reaches a specified high temperature, it will automatically do a shutdown. Best wishes Amir-
