Yeah, wow, that's pretty hot.
Mine runs at 42ºC (107.6 ºF) under a full load, streaming audio and playing a game. 32ºC (89.6 ºF) is the average temp.
I have five fans in my system though, a necessity for the kind of loads that I place on the system.
If your fan is not operational, then you need to look into a software (or hardware) fix.
If it happened at the *exact* moment of the upgrade, then it points to software.
Did you make changes in the BIOS at all? Some control the fan speed, like mine.
Have you checked your process table for runaway processes?
Lappys can't live without the fan. Consider an external fan blowing into the system until you can get this fixed as a temporary measure, or a cooling mat, or both.
