Summary:When I'm doing some simple stuff, the fan quickly gets to full speed and my CPU temp gets to over 90°C. Hello After some browsing, which didn't heat up my computer, I opened up Chess. My fan quickly got to full speed and my CPU temp got to over 90°C. Is this by any means normal? At the activity monitor I see Chess consuming between %95 and over %100. (It sometimes shows a process using more than %100, like iPhoto %160 or sth when first importing pics) Extra infos: i7, 8GB Ram 13" 2013 model Macbook Air with all the updates etc. Update: Just now the fan slowed down to normal but activity monitor still shows same level of CPU usage. Basically my CPU randomly heats up without any heavy load and then cools again. Should I be worried?
