I have a mid 2007 macbook which for the most part still serves me very well. however, as of late it has been heating up WAY too fast. If i watch a video on youtube, try doing any sort of multi tasking or anything that really shouldn't task the computer too much, the temp spikes to 180+ and the fans run full blast within seconds. I understand under longer heavy loads the computer will heat up but I'm talking literally within seconds of doing things it gets way too hot. what are some solutions to this? I am thinking that over the last 5 years, it has probably collected some dust on the inside.... is this a common thing? I've seen several videos on how to take it apart to get inside so thats what I'm probably going to do but I just wanted to see if this was a common thing that others have dealt with. thanks!
