AMD FX-9590 causing freezing issues alongside high idling temperature?

Hello,
For the past week I've been trying to troubleshoot the constant random hanging issue on my custom built PC that only happened after I clean reinstalled W10 onto my system, I built the system about a year and a half ago with absolutely no issues until this point. After running diagnostics on my RAM, SSD and GPU I was able to exclude them from the equitation leaving my motherboard (GIGABYTE 990FXA - UD3 (Rev. 4.0), CPU (AMD FX-9590) and CPU cooler (Cool master Hyper 103) as being the remaining culprits.

When using the Open Hardware Monitor to monitor the CPU's temperature's it is idling at 60c and fluctuating between 60c - 70c which as I have learnt is a much higher idling temperature than it should be. I also have figured out that my current CPU cooler is much weaker than what the AMD 9590 demands but although I cannot figure out why these issues only arose after I reinstalled W10 as I've had no hanging issues at all prior. I'm lost as to why this freezing only occurred after the re-installation and whether my CPU is defective or the CPU cooler no longer meet it's demands. I've underclocked the CPU to 4ghz and lowered the CPU's voltage to 1.25V although it still instantly freezes in Prime95's stress test. Any help would be immensely appreciated, thank you.

Computer specifications:
SSD: Samsung EVO 2.5" 850 250GB
GPU: NVIDIA GeForce GTX 970 4GB Superclocked
CPU cooler: Cooler master Hyper 103
CPU: AMD FX-9590 Black Edition 4.7ghz 8 Core
Motherboard: GIGABYTE 990FXA - UD3 (Rev. 4.0)
RAM: 2 x's (DDR3 8GB Kingston Hyper Fury)
PSU: Cooler master 650W Semi - modular
Case: Graphite Series 230T
Case fans: 3 120mm fans

The first glaring problem is the cooler, the hyper 103 is nowhere near enough to cool the fx 9590. It's a 220w tdp cpu. A hyper 212 evo is a better cooler than the 103 and it's only rated to dissipate 180w of heat max. It's thermal throttling really badly. Recommended cooling for that cpu is a liquid cooler, preferably one with a dual fan 240mm radiator like an h100i.

Do you have bios revision F3 installed? F1 may have been what came with the board and F3 is what's called for when running the 9590.

I'm not sure why these issues didn't occur until just recently. I'd be willing to bet you've been close to thermal throttling most of the time you've had it or never really put the cpu through much stress with that cooler. It can be a real...

It can be a real bear getting that cpu to play nice. Without going through a whole rebuild you might be better off trying to sell off the 9590, getting an fx 8350 and overclocking it. Along with a better cooler regardless. You'll probably find more stability from an oc'd fx 8350 than the 9590 which is essentially just a factory oc'd 8350 pushed to its limits.

Hi VolcanoChip:) Appropriately named too.

You have listed your PSU as the cooler lol. Please list the PSU and your tower case and fans.
The FX-9590 needs an AIO Water Cooler of at least the Corsair H110 or equivalent. You may have been getting away with it if at stock settings but not now.

I recommend you re-apply your Thermal Paste with AS5 and upgrade the cooler.

What version Bios are you on.?

Prime95 is a harsh tester and would Max your temps real quick on Air.
Windows would not be the cause.

Underclocking the CPU would not help without lowering Core voltage. However this is not a solution to your issue.

Hello, thank you for your response and I edited the post including my PSU, case and case fans so thank you for pointing out that error. I have reapplied the thermal paste but I have not used AS5 so I will try to get a hold of it and give it a try, the idle temperature remained at 1 - 20c for around an hour after reapplying the thermal paste then reverted to the original idling temperature. I am running the BIOS on version F2. Is it essential for my CPU to be liquid cooled or could a more powerful fan be a substitute?

Thank you for your response to my post, I currently have the F2 version of the BIOS installed on the machine, I've never updated it since I got the motherboard and I do believe you're spot on with my lack of cooling being a primary factor in the freezing, I'm just amazed my computer managed to survive this far until my problems recently. If I got appropriate liquid cooling for the AMD FX - 9590 do you think my system would be able to manage appropriately or do you think it's essential that I downgrade the CPU to avoid any further problems?

No need to downgrade as the FX8350 and FX9590 are really the same chip except the 9590 is selectively binned as a higher performer.

Also your PSU, if it is G650M is Bronze certified and really barebones minimum for your system.
You should consider an upgrade to a more efficient quality unit that's gold or Platinum certified and at least 850W.

A more powerful fan can help if your case flow is poor and VRMs temps are high from the higher OCs but would not help the CPU temps.

You could start with better cooling and see how it goes. I'm not as familiar with amd cpu's though other sites who have done power consumption tests on the fx 8350 show their core voltage beginning at a baseline of around 1.36v @ 4 to 4.2ghz. As they overclocked the 8350 they went to 1.46 to 1.47v at around 4.6 to 4.7ghz. If looking it at as though the fx 8350 and 9590 are similar, 1.25v may not be enough core voltage to run the 9590 stable at 4ghz as you mentioned when you downclocked and undervolted it. That too could be part of the crashing and instability along with cooling issues especially under stress testing.

Is there a possible chance that my CPU may of been damaged by running at such a hot temperature for I presume a fairly long time as I didn't monitor my temperature until recently? But in the meanwhile I do plan to upgrade my cooling unit which hopefully helps with the cooling situation.

That I'm not sure of, some of it's lifespan may have been shortened though likely a lot of damage was prevented by thermal throttling. Rather than allow a cpu to just meltdown like they used to the newer ones incorporate throttling so they automatically downclock to reduce temps when getting too hot. There's no definitive way to know for certain, it may start having issues a year or two from now or it may work fine for another 4-5yrs. Just about anything is possible I suppose.

Yeah the hanging issue has completely subsided after I underclocked the system but I will try to invest into an upgraded cooling unit so I am able to run it at it's stock speed, thank you both for the help, it's greatly appreciated.
