I am running a AMD FX-9590 Vishera 8-Core 4.7 GHz with a ASUS Crosshair V Formula AM3+ AMD 990FX. I bought a CORSAIR Hydro Series H75 and I was getting great temps for a couple years. A few months ago my CPU started over heating and freezing my computer. I would clean the radiator and all my fans in my case and it helped for awhile. Last weekend after a good clean I was still over heating while playing games. I replaced the thermal paste on my cpu but that didn't help. I figured the liquid cooler was just dying so I decided to put the stock heat sink back on my cpu. This didn't help either, still running around 70C until my computer freezes. I tried another brand of thermal grease this also made no difference. I went into my BIOS and disabled 4 of the 8 cores and this helped a little. After disabling 4 cores I can play games but I still run around 70C but my computer just doesn't freeze, yet. I am totally out of ideas, can anyone point me in the right direction? Thank you for your help in advanced.
Overheating issues,and I'm out of ideas.

If your Hydro H75 is a few years old, it is possible that a few different things may have happened to it.
1: The coolant may have evaporated over time. Especially with a CPU like a 9590, the coolant can evaporate over time. I have experienced it before, and it usually requires a replacement cooler if the cooler isn't able to be refilled (which the H75 isn't without compromising the integrity of the pipe joins).
2: Your pump could have failed, or the tubes may have become blocked by sediment that builds up in the tubes over time. If you cannot feel vibrations/have no RPM signal on the fan header the H75 is plugged into, a failed pump will be the reason.
3: Do you have a Crosshair V Formula, or a Crosshair V Formula Z? The non-Z Formula technically does not support the FX 9 series of CPU as the VRMs are not able to deliver the required 220 watts of power that the 9590 demands. If you have been running with an unsupported motherboard, the VRMs may have become damaged, leading to odd power delivery, which can cause high temps/shutdowns. This is the least likely cause as a non Z Formula should not even boot with a 9 series CPU installed.
Finally, if the stock cooler that your 9590 came with is an air cooler, rather than the AIO that some of them come with, you will find it completely inadequate as the CPU has a TDP of 220 Watts which means that the 70 degrees while running games is expected with that cooler.
I hope this helps 🙂

It could be the CPU is simply unable to maintain that frequency.
CPU's like all transistor chips slowly degrade over time, which is why you should never overclock one just shy of the failure point.
*Go back to eight cores, but downclock as low as possible to test for stability. 3GHz? Whatever. Then if stable find out where it fails then go at least 200MHz below that point.
Keep the voltage as low as possible to maintain stability. If it is the CPU itself, and not necessarily temperature then it's a combination of frequency and voltage likely that will fix this.
(voltage contributes to heat more than changing the frequency does.)

Did you apply the thermal paste with the "pea method"?
Too much of thermal paste could be problematic.
what´s your ambient temperature?
case fans are all working fine?
improve your air stream inside the case if possible by adding or replacing case fans
any tuning tools installed like speedfan or similar?
reset BIOS

Yes, that motherboard does not support the FX 9590, as the TDP limit on the board is 140. I had one of those boards and it was not able to boot with an FX 9590 installed. I am starting to think your board has been damaged by an unsupported CPU.
I agree with photonboy to an extent. As your CPU has a stock clock of 4.7GHz, I don't think that transistor degrade will have caused problems after three or so years.
The most simple solution is to try replacing the cooler, but it may not work if there is another underlying problem.

With the thermal paste I used the "pea method"
I have 5 sensors and they range from 23C-27C
All case fans are fine.
I have a fan controller for 5 fans and I have it maxed at 2,000 rpm
2 - 120mm fans
5 - 80mm fans
I did reset BIOS
I even tried taking my side panel off and using a box fan to cool my computer. Only helped a little.
