My iMac is more noisy than when I bought it years ago.
it is because of the probable dust inside? would it be help to open it and make a good clean? (last week when I put at max speed the fans of the computer with a fan controller software, I saw dust coming out from the inferior part of the iMac)
I was thinking to bring it to a friend of mine who has computer shop. He would be much more experienced than me. He can also put some thermal paste if its needed. Would it help that make it more silent?
PS: it becomes noisy after some hours of working, not at the restart. But I usually never restart the iMac
Is this a good question?
