I have a ryzen 9 3900x and the case is a fractal design meshify C

I'm using a corsair h115i rgp platinum I remounted but used the X formation for the thermal paste this time and it's a tad better. If i have discord running or something and just step away from the computer and do nothing itll drop down to around 43 C, with occasional random spikes to around 53 C. Some weird things like starting a download in steam will cause me to reach temps of like 67 C, and with cinebench it spikes at 74 C. Random things can cause it to spike up to loke 65 C if i have a lot of programs open at once. If i stress test using prime95, the very max it seems to get to (i only ran it for a few minutes) is around 80 C but mostly stays around 57-61 C. Are these acceptable temps? Is it safe to leave it and forget about this?

Running doom eternal on highest settings i seem to be getting between 52 and 62 C. 55 C still seems a little high for idle with few things open. Even something as simple as opening steam caused it to jump up to 67 C for a few moments. Maybe I did the thermal paste wrong or mounted incorrectly? What application method is best? I did the dot in the center. How tight do I need to screw the cooler in over the CPU? Should I press it down on the CPU for a bit and spread it around before screwing it in or something?

None of it is overclocked. Ok so I went out and bought some new thermal paste and isopropyl alcohol to wipe off the old thermal paste, i reapplied it, remounted the pump, and now it seems to be working. It's hovering under normal load (with very few applications open, just what opens at startup) around 55 C. Is that normal?

The pump (if that's the part attached to the cpu) feels like it's vibrating, as do the tubes connected to it. The mount seemed secure but im gonna go out and get some thermal paste to reapply and remount. Could it being improperly mounted, even if some part if it is still in contact with the cpu, cause it to reach those temps? Because it feels like the pump is working and it felt mounted properly.

How do i make sure the pump is running

Keep in mind throughout this thing that im not super knowledgeable when it comes to hardware. I built my current computer with help from a friend who is much more knowledgeable about this stuff than I am. I recently shipped my computer across the country. I drove it myself. I thought I had padded it in the box pretty well, it was flat on its back, and the graphics card was aligned in the car's direction. Now that I've arrived, I turn it on, and the fans are on overdrive, and after I type my login information, and get the little loading icon, it shuts off abruptly. After that I restart it and the boot screen tells me "CPU Over Temperature" and when I go to see more options, it tells me the CPU is currently hovering around 99-100 degrees Celsius. This time when I boot the screen has this weird split down the very middle at the login screen. It abruptly shuts down mid login again. I have a corsair aio 280mm liquid cooler. The part that attaches to the CPU was still secure when I checked. So is everything else. So I guess my question is, how do i know what's causing the problem? The CPU, the cooler, or both? I'd rather not go out and buy a replacement part until I know definitively what needs to be replaced. Or if i can somehow just fix it. Could the CPU being damaged somehow cause it to reach those temperatures even with proper cooling? Should a CPU under normal circumstances be able to reach those temps with no cooling? Also im worried i may have caused damage by even letting it reach those temps when testing.

So I just finished building my first PC. The parts are listed here: https://pcpartpicker.com/user/PCRevolt/saved/P7PwhM Everything about this rig is working very well. The performance seems to be really good, and I got great benchmark scores. The one thing that is bothering me is that the graphics card will make this really loud buzzing sound under high load which I can only assume is coil whine (it's not the fans). I feel like at this point I should state that I only have a barely surface-level understanding of how most of the stuff in this PC works, so I have no idea what's going on or how to fix it, assuming it even can be fixed at all. This doesn't happen all the time. Certain games don't cause it to do this, like if I'm playing Dark Souls 3 at max settings. But if I start up the new Call of Duty: Modern Warfare, it almost immediately jumps to intolerable levels of noise, even when positioned a considerable distance away. Could the card be faulty or something? Because there's no way this is supposed to be an acceptable level of noise. Also I've heard that the coil whine can come from the PSU? How can I determine if it's coming from the graphics card or the CPU? There are so many factors involved with this that I don't know what exactly the problem could be. I'm just trying to determine if getting this one replaced would have a reasonable chance of fixing the issue.
