Cpu suddenly much higher temp

[Remikp04]

While playing rdr2, my cpu was usually around 60 degrees Celsius sometimes getting up to 65 at the max. Now it averages around 70 and reaches 80 even sometimes. I have a ryzen 5 1600 with the stock cooler.

 

Now it used to be on 3.9 GHZ with 2x4gb of 2800mhz ram, then I upgraded to 2x8gb 3200mhz ram and it crashed on 3.9 so it's now on 3.8GHZ and stable. 

 

Now the cpu as I said reaches much higher temps and the GPU, I feel like it's being utilized less and now only goes to 60 max at 99% load when it went to 65-67 before. I guess that's a positive but I feel like that's got something to do with the cpu. 

 

Any ideas on what happened and if I can get the temps back down?
