Thanks, sorry for all the questions.
The NB is cooled with icy water. CPU temp is -87C. There are so many fans cooling the memory etc. that the whole thing would fly out of the window if it wasn't held in place by a 100- pound cascade... I can imagine the headlines if it would land on someone's head!
