Overheating of motherboard can be caused by few faults.
My previous laptop was a dell inspiron.
If the thermal pads below the heatsinks are causing bad thermal conductivity then only this video. These applications check computer system sensors like temperature, fan speed, voltage, and give you precise information. What Causes High Temperatures and How to Prevent Them.
