I have the same issue with heat since my mac is on Sierra. It heats up as I log in and my mouse becomes very jumpy and erratic. I has nothing to do with heat sink. It has to with Sierra OS. I think Apple has concentrated on iPhone business too much where money is and they ignore the OS. Simply SIERRA is terrible. The new comer HIGH SIERRA would be the same if they continue ignoring it. MS Windows welcome back!
