It's Hot in There.
I use my Dell Inspiron 5150 laptop on the patio in Australia and the ambient temperature is 36ºC. I had the processor temperature as high as 68ºC. It didn't appear to come to any harm. I did ring Dell and they said that the computer will shutdown if it gets too hot.
In the UK the CPU normally runs at 38ºC and H.D at 26ºC.
My desktop Fujitsu Siemens has a CPU temp.of 36ºC and H.D temp. of 44ºC.
