I agree with everyone else.
Chances are great one of the pins pulled loose a bit on the CPU heatsink.
By putting in a new PSU and GPU, essentially rewiring everything, makes it quite likely you've pulled one or more of those pins loose a bit releasing the pressure on the CPU. An very easy mistake to make and overlook in such a situation.
Keep in mind, a pin may feel snug to the touch, yet not be seated fully causing temprature problems.
Double check those fins are fully seated AND, the fan is working properly. Also, if you have some compressed air, blow out the heatsink fins and make sure its good and clean.
--EDIT-- Should TJMax be around 105 for that CPU? That will throw temps off.
Im not certain, so do not take for fact. Someone familair with this CPU confirm please?
