Is there any way to make an external alarm go off if your CPU reaches a certain temperature using your serial port? I over-clocked my processor and I get warnings if it reaches a certain temperature, but that would only be useful if I am on my computer.

I suppose so, but serial port? where does serial port come into it? –  barlop May 18 '13 at 16:26
    
If you have overclocked your CPU and its overheating then your overclock is unstable. What you want is not possible. –  Ramhound May 18 '13 at 17:02
