One thing you can do for now, is set the Power Options power Plan to High Performance, this keeps the CPU fan running at full speed and should lower temps a bit if not back to normal. It should run down the battery sooner so keep that in mind if you do mobile computing. In Windows 10 ou also have the Battery Saving Mode to control CPU fan speed. These settings can lower CPU clock speed which also lowers the fan speed and cooling efficiency.
And there's also the BIOS power saving settings to consider adjusting for better CPU cooling.
