I am currently working with a MacBook Pro 15 mid 2010, Core i5 2.4ghz, upgraded to 8gb RAM and 240gb SSD. It is working perfectly for my current needs, but the heat on the left side is bothering me. I already tried to clean the fans and change the termal paste (which was horribly applied) but I did not see any improvements. I use SmcFanControl to check the average temperature and it is normally 60c70c at normal usage and 90c with intense tasks. I think the CPU is warmer than normal, but the topcase temperature is what bothers me. It feels a little uncomfortable when I rest my wrist on it after about a half an hour of usage. What can I do to solve it?
