I'm a little concerned about the temperatures my MacBook Pro has been reaching lately. I have only been using a simple note app (Equil) to sort out my lecture notes in preparation for revision. I didn't think the application would be very heavy on the CPU, yesterday it managed to go up to 90 celsius. Today however I thought I'd take a screenshot of my activity monitor at the time the temp was reading at around 75 celsius, it says the application was using 111%. Can anyone give me a second opinion and should I be concerned? Thanks!
