I had recently updated my MBP to the new OS. at first glance, I did not see any issues. until I was in an environment that I could hear my fan. When I entered the command keys to start up Siri, my fan's rpm's would drop back to factory settings and then resume to the entered settings. I wanted to get in contact with someone from Crystalidea to inform of this "interruption" of software. I also wonder if there are others that are aware of this as well. the new update did not help my situation as multiple uses of Siri at once brought the fan back down to 2000 rpm.
