I'm just going to start by saying that my Macbook is not in the best of health, it has a cracked trackpad, dents on the sides next to the trackpad, multiple screws have come loose and fallen off down the bottom. However, the computer was still chugging through its daily tasks with no real issues. Until one night I opened up the lid after about half an hour and the fans were going crazy and I thought there was a game running that I forgot to close, this was not the case as nothing was running, I have done multiple resets of the computer and nothing has changed. I installed MacFanControl and saw that when nothing at all was open the system fans would run at 6300rpm, the computer doesn't get hot at all from what I can see and I have been using it to limit the rpm to 3500. Is there any fix to what has happened? And is there a problem with manually controlling the fans and is there any tips when controlling the fans manually? Any help is much appreciated
