Hi, guys! So within the last couple of weeks I've noticed my fan becoming much more audible. I'm not sure if it's always been this loud and I haven't noticed or if this is new, but I suspect it's new, because it seems to coincide with me resuming regular playing of World of Warcraft (on my Macbook Pro, 13" mid-2010, running Mountain Lion). A few weeks before Christmas, my hard drive failed and I replaced it. I haven't had any problems with the new one, and when I had the MBP open while I was replacing it, I would have noticed if the fan was overly dirty, unless the fan is hidden away somewhere I couldn't see. I didn't go digging through the inside of my poor MBP or anything. I'm not a computer wizard, I'm just competent enough to replace a hard drive when I need to. iStats is informing me that my CPU temp is currently at 80° and my fan is running between 4600 and 5500 rpm, and the only programs I have running right now are Mail, Pages, and Chrome, and I'm not using Chrome to do anything but read (no video or in-browser games). I always make sure my MBP is on a platform so the vents don't get blocked, so I don't understand why it would be heating up this much, especially when I'm not running anything particularly heavy duty. Help?
