Today while I was using my MacBook Air the temperature jumped really high for no apparent reason it reached 204 Degrees Celsius (CPU). Im not even sure how this is possible, I was just browsing Twitter on chrome with no other tabs open or any other programs. In iStat Menus the CPU was jumping really high, Finder was taking 140% of my CPU somehow. This kept on going for 10 minutes until Finder suddenly stopped sucking up the CPU usage should I do a clean reinstall of Mac OS Mavericks? This isn't the first time that this happened, this happened a couple days ago too.
