I bought it in January 2009. 15" 2.53Ghz, model A1286 with the removable battery cover on the bottom. Used to be my MBP's fans would only kick in when something really CPU intensive was going on or if I had it in bed with me resting on sheets, creating suboptimal thermal dissipation conditions. See the first screenshot for what it's usually like now. I just read http://forums.macrumors.com/showthread.php?t=338864 and http://forums.macrumors.com/showthread.php?t=469904&page=2 and figure that my best bet would be to clean out my MBP's fans. I searched iFixit trying to find a guide specifically for cleaning dust out of an MBP but did not find one. Does anyone know if they have such a guide? If not, which of their guides should I use? Lastly, do you agree that I should try this? As I type this, my MBP's temperatures have stayed basically the same and the CPU is barely being used. All I'm doing is creating this post! Thanks in advance! By the way, recently THIS has also started happening once in a while: http://gallery.me.com/eeljazz#100050/Macbook Pro Feeling Sick Can't be good. And no, I don't have AppleCare. Will have it next time, though.
