Question Ryzen 7 2700X crashes with high temperatures ?

[Vlad24]

I am doing 3D rendering and every time I start rendering of a heavy scene - my computer crashes after roughly after 30-60 minutes. The screen turns off, windows shuts down but the PC indicates that it is on and fan is still working (on regular speed after crash). What is strange is that motherboard indicator has only DRAM blinking. Can only turn it off and start again. I concluded that it is happening because of overheating CPU (Ryzen 7 2700x).

There are 3 reasons to assume that:

- I was paying attention to the temperature through the fan control software. While rendering, I put the fans at full speed and often see temperature reaching 80C and above. I have not seen the temperature go above 88C but I assume it crashes somewhere once it reaches threshold of 90C.

- I did some cleaning and removed old thermal paste, cleaned heat sink, reapplied a new thermal paste and after that crashes stopped for a while, but recently came back again.

- Rendering on GPU doesn't crash.

Now, I was considering 2 things - either buy a new CPU (this one is 3 years old) or a AIO liquid cooling. I am unsure if either will solve my problem as AIO cooling might not be as efficient as manufacturers make it look so (compared to the cooler that came with 2700x) and even though everything points to problems with CPU, it is still weird considering that 2700x meant to work at temps all the way up to 105C. In case I would need to do more troubleshooting - I would love to know how to do it since event viewer doesn't tell me anything useful.

Thanks!

list all parts and use hwinfo to check temp and others i suspect the gpu that overheath and cut off on black screen

Motherboard: ASUS TUF GAMING B550-PLUS
CPU: AMD Ryzen 7 2700X
GPU: GeForce RTX 4070 Ti
RAM: Kingston kf3600c16d4/16gx
OC: Windows 10

As for the temperature of GPU: during render it doesn't matter, as I mentioned I render with CPU, temperature of GPU doesn't change and stays within 35-40C degrees. No problems when rendering on GPU.

What CPU cooler is it?

My old 2700X used to crash when it got up around 80 or so. I only fixed it by using an AIO.

It is the one that came with the cpu. Wraith Prism.

Considering the age and the workload that will only increase would it make sence to buy a new CPU or try to solve this problem with AIO cooler? And do other AMD cpu's have similar problems?

That's probably a chunk of the problem you're having then. If there's decent airflow in your case and clearance you could just get an inexpensive tower cooler and likely be fine. Depending on where you live you could potentially get something like the Thermalright Peerless Assassin dual tower for under $40 USD.

Thanks for the advice. I will check other options. I have one fan in and one fan out, is there a way to know if my airflow in the case is good?

If it's an issue of cooling then go into bios and change the TDP, use eco mode or just decrease the power, if it has PBO (auto overclock) enabled just disable that.
At least do that as a sanity check to see if it is really due to temps.

What case is it? Usually you'd want more than that, but depending on the case there could be other issues.

Thanks for the advice, I will certainly check it out. Is it fair to assume that if the problem is just CPU cooler I will see higher temperatures in CPU parts during the high loads and if the problem is the case airflow the temperatures will rise in all components?

While that design leaves a lot to be desired (unless you're using the side intake) it should be okay for what you have installed. A tower CPU cooler will work much better in that case than the downdraft currently in use.

The CPU will always be much hotter than anything else in a system under load even if everything is perfectly working.
Airflow will just help the CPU cooler and give you a few degrees better temps, or fewer if it's not so good.

Since OP has mentioned being on the stock cooler I think there well may be other solutions that don't involve kneecapping performance.

Mine wasn't a solution but a sanity check to see what solution he might need.
If he lowers power and it still crashes then it's obviously something else right? And he would have spend a buttload of money on cooling or a new CPU without any reason.
It could be from the ram controller if it was running XMP, or the VRMs might have come to the end life.
It's not out of the question for the VRMs to cook themselves.

Ok, to close the topic - problem solved. Thank you all for your input, it turned out to be more trivial than I thought. I had 2 fans oriented to exhaust, and none to intake. I noticed it when I was installing new fans (+2 for intake, and replacing an old exhaust with a new one). So, now that I have 3 intake fans and 1 good exhaust everything works very well, doesn`t go above 77C on high load and, as the result - doesn't crash.
