Threadripper 1920x Clocks at 0.52GHz and Overheats

This morning I updated to the latest version of Windows (likely not relevant) as well as my Adobe Creative Cloud suite (also likely not relevant) and turned my computer off. After a few hours I returned home and started my computer up. It ran for roughly 5 minutes before starting to slow right down and eventually turning off. At first I thought it was a power issue so continued turning it on although it continued to turn off. 

After some inspection it appears that on startup the CPU begins at 60C but then makes it way up to 90C+ before the PC shuts off completely. There's only 1% utilisation on the CPU and hardly any on the RAM either. I bought some thermal paste and reapplied to the CPU although it didn't make a difference.

My only thought is that the Corsair H100i V2 is running fairly hot but I hadn't noticed any corrosion or damage where the thermal paste was. The PC has run for 5 years without any issues. Is there anything else that could be causing this or do I just have a dodgy Threadripper CPU?

 

PC Specs:

AMD Ryzen Threaripper 1920x

Corsair H100i V2

4 x 8GB Corsair DDR4 Vengeance 3000MHz

Gigabyte X399 AORUS Gaming 7 TR4 ATX Gaming Motherboard

Seasonic Prime 750W 80PLUS

Some screenshots before the CPU completely overheats and the computer shuts off:

Instead of saying you have a dodgy threadripper, go buy a new cpu cooler!

 

All your information indicates a faulty cpu cooler or incorrect installation of the cooler, yet you think its the cpu

Thanks for your reply. What makes you think that it's the cooler?

Is there something that I can do to test this?

That is a clear indication, that the cpu cooler has no, or little to none contact to the cpu to transfer heat away from it

 

Easiest way to be sure would be to check with a new cooler, since you already changed the thermal compound

Did you check for leaks of the corsair cooler?

Yes I have checked for leaks but found nothing! The computer is cleaned regularly, roughly every 1-2 months so not a dust issue either. On startup the CPU is only running at 0.5MHz (usually sits at 3.5GHz+) which is why I'm leaning towards CPU failure. 

As I mentioned previously, the entire build has been untouched and running for the past 5 years without failure - this is why there shouldn't be a contact issue between the cooler and CPU.

Re: Threadripper 1920x Clocks at 0.52GHz and Overheats

Your CPU is thermal throttling.

 

If you have been running a AIO Watercooler for 5 years, it definitely looks like a cooler problem.

AIOs tend to leak after some years.

My first AIO (Corsair H60) leaked after almost 2 years.

 

Anyway, if you want to lower your temperatures and prevent thermal throttling you either have to check for contact between cpu and cooler plate, thermal compound, leaks, or just get a new cooler, to save time and hassle

Thanks for your response.

Is it not odd that the CPU was running at 0.5GHz? It usually sits closer to the 3.5GHz mark so I assumed that this meant it was on the way out.

iCue was giving me readings for the cooler's temperature, pump speed and fan speed so I would have assumed this would be enough to say that it's working properly. Regardless of that I have submitted an RMA under warranty to Corsair as it's just under 5 years old. 

I'll let you know how I go.

The CPU Downclocks to 0.5Ghz to lower the heat output and protect itself

Lower Clockspeeds->lower temperature
