During Racing Sims, Inexplicable Crashes / CMOS Reset

[Alex1]

Thanks @phillpower2. My case: Rosewill Line-M MicroATX. I think your idea of moving up in size is solid.

Quick question before posting my data, are temps after longer idle periods useful or should I run a demanding program first?

[phillpower2]

Your case at least has one front fan so am a bit surprised that your temps are so high tbh.

Run the programs on boot if you like as that will give us an idea of the general temps.

[Alex1]

I started up Assetto Corsa Competizione so these readings will reflect a short time with that heat load on my components. (that’s run the hottest as of late). These were also taken with case open and desk fan running at gpu.

[phillpower2]

Did you do those screenshots as per the steps in my reply #60.

We can see a couple of high temps there + one of the cores on your CPU is spiking.

NB: One of the high temps is for AUXTIN which is the power supply temp sensor when there is one.

[Alex1]

Apologies, no.

Since those readings were taken with the the case open, it makes me wonder how much a larger case would do for my build’s temperatures.

When you say “spiking” are we looking at dangerous temps?

[phillpower2]

Can you redo the HWMonitor ones again using the steps provided and be sure to check that the info starts at the top of the page.

The spike in the CPU is not regarding the temperature but that particular core or thread being busy as in processing data, it could be an anomalous reading but it does look odd.

[Alex1]

Gotcha.

Hope these shots are better.

[phillpower2]

Better (y)

Same couple of high temps, some missing voltages and a couple of high voltages.

The high temps could be the chipset and the high voltages either the RAM or mosfets on the MB.

Please restart your computer and check the temperatures/voltages in the BIOS, no screenshot is required just make a note of the temperatures, the DRAM voltage, the +3.3V, +5V and the +12V rails on the PSU and post them with your next reply.

NB: BIOS voltage readings.

The readings are not conclusive in the BIOS as the computer is under the least amount of load, if they are higher or lower than what they should be though it most often suggests a PSU problem.

[Alex1]

DRAM voltage: 1.200
+3.3V: 3.328v
+5V: 5.016v
+12V: 12.144v

[phillpower2]

They are all spot on so that leaves an overheating chipset which ties in with the improvement when you directed the fan into the insides of the case.

[Alex1]

I’m gathering it would be safe to say that when running system-taxing racing simulators, don’t use a micro ATX build and make sure to create more airflow than would be usually required.

Hoping my hardware has not sustained any damage from the consistent high temps.

[phillpower2]

Any high end build needs better cooling, cheaper cases that are mostly made out of plastic are even worse than a steel chassis.

[Alex1]

As a conclusion, I posted a week ago regarding consistent unexpected shutdowns during racing simulators known for taxing systems and after multiple diagnostics, chipset driver updates and an OS update, we determined heat was most likely the cause of my system’s failures as the 87-88c GPU temperatures were not isolated spikes but “normal” operating temps during these sessions.

As a very temporary solution, I have been running my PC with the case open and a fan pointed directly at the GPU. It seems to be helping as my GPU has rarely gone above 86c since. (24 hour period)

It has been recommended I upgrade my case to allow for increased cooling of the system.

Thanks very much to @phillpower2 for walking me through multiple steps in updating and monitoring my system.

[phillpower2]

Almost 100% correct but the idea of the fan was and is to blow cool clean air across all of your internal hardware and for cooler cleaner air to be drawn into the PSU as well.

You are welcome
