... but I'm not sure. Anyway, A few days ago, it was making a nociable fan noise. So bad I almost considered making an appointment with the 'geek squad' to either come over to my house (They make house-calls) or to bring it in to BB. I ran SMC fan control as high as it would go for a few minutes a few times (when the noise was really bad) could it just have been some kind of blockage (dust particles probably) and the extra fan power blew it out. I had also used a vacuum to clean the back out, too. Just wondering. It's running fine now and no 'wierd' noises at the moment. I am kind of thinking it's just because the heat that got to it and when that happens just set it on a hard surface for the duration of use?(Of course, AFTER a 'cool off' period for a few hours.) It's now back to being so quiet that I have to put my ear close to the keyboard to hear if the fan(s) are actually running. I actually now think my own body temperature contributed to it. The reason I think this is because I have a 'speck' case on it, and after using my MBP for a prolonged time, I get a 'skin design' from the bottom half of the speck case. (I am wondering if I 'blocked' off' the air circulation with my own legs because I usually have them propped up for more comfortable usage. (I also have a fan on wherever I am, so the fans in the MBP and fan on the outside will help keep it cool and noiseless.) I'm sitting here at a table and the fan(s) is/are registering at upper 40*C's to mid 50*C's. Thanks. PS. When I can or get arround to it, I am going to buy an 'X pad'. Which brings me to anouther question... will a cooling pad that was used on an old HP laptop work with a MAC notebook. (Would the slots that you can plug things in be too big/small? I am not sure if it was specifically designed for laptops that weren't MAC's or not.
