@djreej, it's not MSI afterburner. The problem is your CPU cooling. When you installed your cooler, did you use thermal paste? Whether you did or not, I suspect it wasn't applied properly. Please let me know and I'll be happy to talk you through it, or you can search thermal compound on YouTube and view for yourself.
You need to clear the old paste (if there is any) from the top of your CPU and the bottom of the CPU cooler with isopropyl alcohol. You need to apply paste to the top of the CPU. It should be about the size of a long single grain of rice. Even though you're using the stock cooler, and I agree it's a great idea to upgrade it, even the stock cooler shouldn't reach 100 C if it was installed correctly with thermal paste.
