Download SMCFanControl and keep your MacBook Pro cool that way... me and my son do exactly that. If it begins to overheat we just turn on the FanControl and wala... it's cool again. For some reason the fan stays on default when the laptop works harder. I would think the fan would bump up automatically but it doesn't... so a free download of SMCFanControl did the job. No warranty issue, no visit to the MacStore just a search in YouTube. Good luck and be blessed.
