I am really sorry about that . maybe you have played for long hours again and again , I personally would not play more than 3 hours with my 360 even though I have attached Nyko 's Inter-cooler  to my console .   also after playing I give the console nearly 2 hours to rest . so far I have not encountered any problem

BTW : I loved the part in which you said : might be putting words into my 360's now-silent mouth
