The first thing that comes to mind is that you have removed the heat sink and fan assembly from the CPU which means that you will need to clean the surface of the heat spreader of the CPU and the heat sink and then reapply the thermal compound which was installed between the two.
The thermal compound is important as it provides a molecular bond between the CPU and the heat sink which enhances the thermal convection increasing the cooling of the CPU.
The second thought is did you bend any of the pins of the CPU when you plugged it back in?
Family and loved ones will always be a priority in my daily life. You never know when one will leave you.
