Are per title.
I have just installed Ubuntu Mate 16.04 latest beta. A fair number of times, I will boot up and log in and immediately find the cores are running around 70c with the fans spinning up high to compensate. It doesn’t help to wait for the system to calm down as this high temperature will persist well into a minute or so.
I find if I then log out and back in again, the temperature will immediately drop down to a more usual operating temperature of around 38c and will be okay for the rest of the session.
Anybody else experiencing this and do the devs have any answers as to what might be going on?
Also, just as an aside, I recently played around with the latest version of Debian Jessie and it also has this issue with core temp at initial bootup and was also fixed by logging out and then back in again.
