    Hi

    I think some kind of background processes stress the CPU.
    You could check this in task manager-> processes tab
    Click on CPU column to get the processes ordered and to show all the processes which stress the CPU.

    Closing or disabling such processes can help to reduce the CPU performance.

    Check which processes are running and try to disable all useless stuff running in the background.
    Try also to reduce cooling fan activity changing settings for cooling method.
    This option you can find in advanced power options.

    Which antivirus application do you use?

    Hi

    All the tips and recommendations by previous users are right but you should also check if dust does not affect the cooling performance.
    Since the unit is a little bit older, I guess the dust might be the reason why the fans are running often. The cooling air cannot circulate properly and this might be the reason for the higher temperature.

    I recommend you to clean the cooling fans using compressed air spray. It can helps to get the notebook running more quiet
