Anyone else notice the fans of their Mac spin up more frequently since updating to macOS 10.2.1 (build 16B2657)? On my retina iMac (see attached image for specs), even browsing/scrolling on Facebook (using Safari) can make the fans spin noticeably louder from time to time. This *never* happened before this particular update.
It also happens when I bring up "About this Mac -> Storage -> Manage" when I have a couple of other apps open as well.
I found an old installer of one of the GM builds and installed it on an external HDD. Fans stay much quieter throughout usage there. Updated that copy to 16B2657, and much more audible fans...
I have reset SMC and PRAM, to no avail.
