Hey there Barryhart1, and welcome to pchelpforum.
hi my fan is working over time because my friend changed the setings then went on holiday i dont know how to put it right
Are you talking about your
CPU fan?
Do you have any motherboard monitoring programs installed in your system?
Do you know which program your mate used to change the settings?
And lastly you say your fan is working overtime, what makes you think this?
