Does the PD 820 have a onboard sensor because hwmonitor or coretemp will not show a temp, the intel data sheet shows the processor has tcontrol and the thermtrip signal, so i am guessing there is a sensor? This is just an old computer that im a practicing oc'ing so any tips on that will also be helpful, i dont want to overclock it without knowing the temps. the cooler is a dell stock with 6 heatpipes and a 120 mm fan.
