Q: CPU usage and Mail Web Content

I have had a problem with macOS Sierra and Safari 10 where the CPU load for any tab was around 140% and the fans whizzing away, this has been resolved by disabling Trusteer Rapport. However I still have a process running "Web Mail Content" running at 199% and the fans loading up every so often. Is this normal (seems a little high) or is there something else I should disable/enable?

Thanks

MacBook Pro with Retina display, macOS Sierra (10.12), Early 2013

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.
