Overheating problem

http://ubuntuforums.org – Ok, I don't know if this is the right place to post this. If it isn't, please move. Up until a moment ago, my computer was working fine. Then, I restarted it, and noticed my cpu's were working at close to 100%, and the temperature was getting over 80 degrees C, when it's normally hovering around 50-60. Here's a pic: What's wrong? I'm running Ubuntu 12.04, on a Dell inspiron 1525. Thanks in advance. :) Attached Images Screenshot from 2013-06-15 23:29:39.jpg (102.0 KB) (Hardware)
