I don't think that there will be any noticeable difference in the temperature regardless of the position of specific water cooling part. The coolant will be moving so fast it wouldn't really matter. If you had more components being water cooled then maybe there could be a difference, but it would be more because of the fact that the flow will more restricted. The more radiators, blocks and fittings you have the lesser the flow will be. This is also why some people opt to have separate loops for CPU and GPU or if these are under the same loop, do add a second pump.

That's fine, see the second paragraph in my previous post about the temperatures. If those are fine as well, next thing to rule out would be the power supply. Usually random power downs and restarts under a high load are either temperature related or power related.

User benchmark is not a "benchmark." Don't use and don't look at it, it's complete garbage. There should be a special circle in hell reserved for whoever invented it and all of its derivates that have popped out.

Is the BIOS updated to the latest one? Have you overclocked anything? Do you have XMP / DOCP enabled for the system memory? If you do, disabled it, as that is essentially overclocking as well. Run the memory at 2133MHz or 2400MHz and see if the computer will exhibit the same issues. Another thing to check are temperatures of the processor and graphics card. What are the temps at idle and under load? You can use HWiNFO64 to get the readings. Download 3D Mark and do a couple of runs of the Timespy and Timespy Stress Test. See how that goes and if the same reboots will be present.

By wiping the computer do you mean doing a fresh Windows installation, not that refresh thing? if you are reusing an old Windows install this may very will be the cause of the issue.

If the speakers short out they will most likely damage the particular USB port where they are plugged in. So yes, technically speaking the motherboard can get damaged. However, why do you believe that the speakers will short out. If they work fine now and you are not manhandling them like crazy or messing with the circuitry inside of them there really isn't a reason for them to do so.

If your overclocks are too aggressive, sometimes you will see a regression in scores. This is why you always need to make a reference bench run with the card at stock. Only then you start messing with it and evaluating the scores. if you see a regression this means you have gone too far. Another thing, the 6800XT reference cards do get hot so overclocking on them is a bit limited because of temperature issues. Try reverting everything back to stock. See how the scores are. Then enable rage mode and see again.

Upgraded the system from what to what? Was it a software upgrade or a hardware one. What are the specs of this system?

Should be fine. If they are USB speakers then should work.

Looks like a good well-balanced rig. That being said, if you are after high frames with good visuals on 1440p, 6800XT would be the way to go. Power supply should be enough as well, even for a 6800XT. These cards are quite a bit more efficient than the nVidia equivalents. Like it has already been said earlier, reference AMD cards are "reference" regardless if they come directly from AMD or from a board partner. It is essentially the exact same card, only difference is the branding on the box itself. The cooler and pcb will be an exact match. Therefore, it wouldn't make any differen

Are the processor or system memory overclocked in any way (including XMP)? You have 4 sticks of 16GB each? What is the speed the memory is running at? Try removing two of the sticks and running the computer like that. If it works fine it could be that the memory controller on the processor is just a bit week.

Your temps look just fine. In fact they are very good. 73-75C is well within the normal operating temperatures of your graphics card. Thermal throttling happens usually above 100C. Warzone is notorious for being badly optimized and some updates of the game do negatively impact the performance.

I don't really understand the question you have. Why do you want to change the power plan to power saving mode when gaming? You want your computer to perform worse and for you to get lower FPS? Where are you getting this 0.8V from? Are you sure that is CPU voltage? Which software are you suing to get that number? Sharing screenshots and explaining your issue in better would go along way in order for anyone to be actually able to help you. What are the full system specs of your computer?

Graphics cards don't usually cause no POST or power-cycling issues. What system memory are you using? What speed? Are you running XMP/DOCP? From the symptoms you are describing sounds like the motherboard is failing to train the memory when first booting up. That being said, if you are getting a CPU debug LED to light up, there might be something going on with the motherboard itself. Try reseating the CPU and updating the BIOS if you have not done that already.

You have already done quite a bit of troubleshooting so the only thing that I can think of are memory and primary drive issues. You you said your memory is 3200MHz, but you where running it at 3400MHz, but since you had issues you put it back to "stock." This 3200MHz is it XMP or JEDEC? If it is XMP, disable it and run them at the standard JEDEC specified speed for these modules (2133MHz or 2400MHz). See how it the system will be performing then. Most often than not XMP doesn't really work properly, as the motherboard is left with too many values to figure out by itself, and not al
