FPS drops then crashing

[Zapapi]

Recently bought this computer (spec: rtx 3070, r7 5800x, 32gb 3200mhz ram, b550 plus AC-HES, 800w psu) that was a prebuilt I tinkered with for upgrades I already had. Had it for about 3 weeks and its had its kinks I've more or less worked out but the large one is that recently, when playing a game the FPS dropped to about 20-30 for about a minute or so before crashing. I associated the crash with being some thermal throttling since I had the settings cranked and the issue resolved itself since from lowering settings. Then as of today, I turned on my pc from idle, was just watching a stream on twitch (discord, spotify and steam were open but not in use) and the fans ramped up, my fps started dropping before it crashed, twice. If anyone knows what might be causing this I'd  be super grateful ! If you need more info just ask, and I know my way around a computer, not so much bios tho, if I need to work on hardware issues.

Are you monitoring temperatures?

[Zapapi]

This was just after turning on the pc and having it at idle. First crash today I wasn't looking at temps, it crashed when I tried opening task manager/ my temp read app. Second time around I was checking and nothing seemed off, after a few minutes it just randomly started fps dropping then crashed.

 

Edit: As of about 30 minutes from the crashes, I've been monitoring temps and usage%. Everything has been fine and no crashing has occured.

Just to be clear are the computers temps usually good?

[Zapapi]

My current temps at idle as they've usually been at are as follows: CPU: ~40°c, MoBo: 52°c, GPU: ~45°C, CPU hotspot: 56°c).

 

[Mandom]

For idle they look fine as expected, although fans ramping up for twitch and discord is not normal. Can you run some Cinebench runs back to back and post temps ?

[Zapapi]

So, trying to download cinebench led to a crash. Looking at the temps, it shot up very quickly to 80, 90 then shut off at 99. 

[Mandom]

Well that's pretty decisive, you probably have cooling issues with your cpu(here are some reasons that might be the cause:someone might have forgotten the plastic sticker in the cpu cooler during installation, thermal paste application might be bad, cpu cooler fan is broken but you said it ramps up). Now you can either get some thermal paste and repaste it yourself or get someone you trust or a technician to do it for you. 

[Mandom]

Oh wait you said trying to download did this damn, i thought it would at least do this when running Cinebench. One more thing, since this is a prebuild this behavior is their problem and they should have to fix it under warranty since the computer is pretty much unusable.

[Zapapi]

I just redid th e cooling application, it looked a little thin so I'm hoping that was it. It's an AIO tho which I haven't used before. I'll hope this works, if not then I'll have to give them a call. It's just strange that nothing has happened before now.

You can retest with cinebench. Throttling is very easy to spot, install msi afterburner and monitor temps and core clocks when running intensive programs like cinebench, if the temps continue to rise and the core clocks decrease then the cpu is throttling.

[Zapapi]

For anyone still here, after changing the thermal paste. The current idle temp that its hanging at is ~32°c which is an improvement from the 40°c before. When I started the pc up, the temp and fans were ramping up (CPU topped at 70°c) for a few seconds then dropped back down which from google, it says I shouldnt worry about it? I'll update if I can download/ run cinebench!

 

[Zapapi]

Ok so after running Cinebench (it downloaded just fine haha). Through the test the top temp my cpu hit was 83°c on the fourth back to back run. Usage was at 100% and the fans ramped up nice and the score was 5593 (idk how the ranks work). Not a crash since the reapplication of trhermal paste/ retightening.

Any thoughts about this?

 

[Mandom]

i see online scores for the r7 5800x be around ~6000cb, so yours is a bit low( you might not be running your ram at full speed in bios), and the 5800x seems like a hot chip so a peak of 83c is not unreasonable, at least now the computer is stable and working as expected?

probably this. what brand/model is the psu?
