But, in practice it may not be. Also, inspect the space around the socket. It can be blackened, which indicates burnout. Try changing the thermal paste. Remember that it is impossible to cover the details of the thick layer paste. It needs to be thin and uniform. Then assemble the CPU and turn on the computer.
