MacBook – Ridiculously high CPU temperature and fan speeds on MacBook Pro Retina, late 2013

macbook promonitoring

The temperatures on my CPU cores spike up for no reason sometimes. This bumps my fan speeds to run near 6000 rpm, which is extremely loud. I know this is not normal because my previous Retina MacBook Pro, early 2013 never ran at this high fan speed, even when the processor had a greater load to process and more memory was used.

Does anyone else have this problem?

By default iStat Menus reads in Fahrenheit. Those are not unreasonable values for Fahrenheit. Go into the settings and switch to Celsius.
