AMD FX-4170 Overheating recently

[Leprechaun003]

Specs
Mobo: SABERTOOTH 990FX R2.0
RAM: Corsair Vengeance 8GB DDR3
PSU: Thermaltake W0382RU Modular Power Supply - 750 Watt
PCU: AMD FX-4170
GPU: AMD Radeon R7 200 Series
HS/F: Thermaltake TR2-R1

Problem:
Within the last week or so, I have been noticing my PC was running slowly, and decided to open up my Taskmanager. I was really only running Chrome at the time, might have had a youtube video open or something, but was almost at 100% cpu usage. Even after shutting down chrome, and ending processes it was still running extremely high for essentially being idling.
Long story short, I restored PC to about a week earlier, and it seemed to run okay for a day.

After that, I decided to play some actual games, and within minutes my PC had apparently overheated and shut itself off. I have since thrown every extra fan I had into my PC (4 total 110mm I think), purchased a new HS/F (Thermaltake TR2-R1) put it in this afternoon (had thermal already applied).

It's certainly running better, but still will freak out and overheat if I try to play something like Smite on ~medium settings, something it used to be able to do on High, no problems.

Here's a CPUID HWMonitor Screenshot of what it's doing right now, with only Firefox, Skype, and some other monitoring programs running.

I have to assume I've done something wrong, or something in my PC has decided to die on me (it's all around ~2 years old) I would guess maybe CPU or PSU, but not really sure.

If I need to add any more info, please be specific

Any help solving this would be greatly appreciated!
Thank you!

Sounds like it could be a voltage control issue either with the PSU or the Mobo. I would buy some decent thermal paste and not use factory thermal paste, then perform more testing. Another thing I saw based on your setup the Thermaltake TR2-R1 per their website is designed to support up to 95W. Your CPU is 125W.

Were you using the stock HS/F before this one? Another thing, what kind of case are you using? I doubt the issue is airflow based on you adding 4 fans in as long as they are setup best for that case.

Cheapest testing off hand would be to get some good thermal paste and see what happens and possibly a different HS/F imo, but I do not know if a bigger one will fit your case really. Best of luck.
