So I use iStatPro (widget) that tells me pretty much everything going on with my computer from network activity, fan speed, memory usage, and temperature on the CPU, Memory, and Battery. I have been using it for about 6 months now, and my temp on my CPU is usually about 105-115 degrees F. However, the past 2 days, it has been at the least 140... and even all the way up to 165. I have also noticed that my performance has been much less than normal. I havent installed or changed anything recently, and I have restarted a few times. I checked activity monitor, and nothing seems weird. Any ideas on what is causing this, and what to do about it? Right now my iBook is hot to the touch over the hard drive, almost like its been sitting on my lap or on a bed or something while doing something processor intensive, but Im not really. Usually just mail, adium and safari. Also, i use an iCurve all the time so it gets good air flow. Thanks.... and it really is hot.
