Look up the accepted running temps for your cpu at idle and under full load. Depending on various factors, Intel chips for example run at idle temps between 30 and 50 deg . Anything over 85 can be a problem.
Install CPU-ID and HWMonitor (HWM)
CPUID brings you system & hardware benchmark, monitoring, reporting quality softwares for your Windows & Android devices

Close all apps so the system is at idle and run HWM.
HWM will then show motherboard temperature(s) at idle for the cpu or cores as well as other temps emmanating from the board, like temperatures for memory sticks, graphics card, etc. If the cpu values are within the normal ranges for your processor, then it is not over heating.
If you run that machine hard, called full load or even partial load, the cpu may still overheat . Lets see. Run CPU-Z which shows data for various motherboard functions. The one TAB you are interested in says "Bench": so activate "bench cpu". That runs all cpu/cores at 100%.Look at HWM.Temps under the maximun ?
If the temps run higher than the maximum recommended temps heating is likely a problem
if you run the machine full out-not likely usage of laptop) .
You can leave HWM running as you use the machine to determine temps under regular use. As long as cpu temp stays within normal range, no problem.
Report temps here if you want. Actually there is a forum for just that discussion.
Discussion about CPUs and Microprocessors. Need help with that new CPU? Like to push it to the limits; overclockers welcome here!
