Recently my laptop cooling fan has started this thing where it makes a sound much like if a CPU fan was rubbing up against a wire, which worries me. I am not sure how serious it is or what I should do about it but it is starting to make me nuts. I think the fan is running more than it used to but I really don't know as I wasn't able to hear it in the past! I guess my options are to either take my laptop in and have it looked at or (if I am brave) open it up myself. I know that taking it in will cost 80 dollars for an overall checkup and thne they will credit that towards anything that needs to be done. What should I do? I have a Toshiba Satellite Pro M15-S405. Has anyone taken one of these apart before? I just don't know how serious this is.
