    Anyone else get high fan speeds with Sierra? Like constantly running?

    I've reseted the SMC and PRAM, but to no avail.

    Thanks for that.

    I've done that a few times and still the same issue.

    I don't really want to do a reinstall of El capitan in hopes Apple will fix this.

    It's an upgrade from El Capitan and haven't changed anything in the system in terms of apps.

    el Cap was pretty good/stable and didn't kick in the fans.

    Same here. Quitting Sierra and using Firefox quieted things down.

    I use Chrome, that may be the issue (even though I use tab suspenders which makes Chrome not eat too much RAM).

    I'll try FF until this is fixed.

    Am now back on Safari and the fan issue has mysteriously gone away!!! Though MBP can run fairly warm.
