Hey guys, I purchased a macbook pro 13 inch completely loaded on november of 2015. Now every time I am playing a game or watching videos for a while and the fan kicks in it lags really bad. Normally on my game i get around 50 fps and it drops to 13 or 15 max 20. Now I contacted apple support and they ask me to restart my computer and it worked fine but all i just need to do is record a moment when it happens. Now I do have extra apple care and i am still under the 1 year warranty either way. I was thinking about maybe if i can show that there is something wrong with this laptop i could exchange it but for a 15 inch one and pay the difference or something (maybe just get the one with a similar or lower value). If this possible? Under what circumstances do they approve this? thank you.
