I have a Mid 2012 Macbook Pro 15" that ran into some thermal throttling issues in Bootcamp, running Windows 7 Ultimate 64bit (Basically FPS drops becoming increasingly frequent as temperature rises) last year, it was seemingly fixed when the logic board got switched. However a few months ago it came back, and I am all out of ideas. SMC and PRAM reset didn't work, and there are virtually no change in terms of settings or temperature before or after the issue came back. And now that I am all out of Applecare, along with the Genius Bar staff being less than useful most of the time, I don't really know what I should do. CPU temperature are always around 80 to 85, while GPU temperature always stay below 80. Any help will be appreciated about how this can be resolved, or just what is happening to my Macbook.
