Sep 27, 2016 9:02 AM in response to danielfromfarehamby Starr.C,Hello danielfromfareham!
Welcome to the Apple Support Communities! Your question about your fans running high after upgrading to macOS Sierra is greatly appreciated. I know if my Mac were to run loudly after upgrading, I'd be concerned too. It's my pleasure to help in any way I can today.
When running into fan issues, you'll first want to try an SMC reset. I have an article that will walk you through the steps:Reset the System Management Controller (SMC) on your Mac
Take care.

I had the same problem with Mail and Safari both using over 200% (not sure how that's possible?) of the CPU. Resetting the SMC has worked perfectly... thank you
