Would anything still in the downloaded files and or updates cause the fan or fans to run really high and a bit (obnoxiously) loud? I've cleared out anything I've downloaded (from updates from the machine) The noise isn't there anymore. The noise I mentioned hasn't happened at a rate where it would be annoying to me or anyone around me. When it gets to the point of being nerve-wracking. I just stop what I am doing and just come back later. I also think that maybe I forgot to install an update for SMC fan control... I am, however, keeping SMC fan control on to keep my MBP cooler in the summertime or when I can get outside. Thank you.
