What system temperature (SYStemp with hwdoctor) do you have with your DFI G5M100-N mobo? Where is this sensor located?

I find my system temperatur to be high, 46-50 Cels, and is sometimes trigging the alarm. I'm using the Travla C138 case with 3 fans and the temperature inside feels ok. My CPU temp is 35-42 cels.
