Several issues arose after upgrading my PC.
Hope everyone's doing well. I've been reminding myself to seek input on a few issues related to the recent PC upgrades. Previously, I had a Ryzen 7 3700X paired with an RTX 3060, and now I'm looking to boost performance further. Recently, I bought a RTX 3080, a Ryzen 9 5900X, and a new 1050W PSU for balanced power usage. My motherboard is a B450 Tomahawk (non-MAX), originally designed for older models, but after some research, they released a BIOS update that supports the newer 5000-series chips. We managed to install it, flash the BIOS, and the system started up without problems. Windows launched smoothly, and I ran some games to check stability. The biggest issue I faced was with the CPU. When powering on, the CPU light appears briefly, and we often see a black screen before booting. It's frustrating because I can't shut it down without using the PSU. I usually have to restart 2-3 times until it loads properly. Another point raised was the CPU temperatures. They would spike to around 70°C during idle with light loads (around 5-8% usage), then drop back to a normal range. During gaming, it stayed in the 70s, maxing out at about 80°C. I know this chipset is high-end and my board's VRMs can get hot, but that shouldn't be a problem. I think the main reason for poor performance might be the CPU handling the boot process—my AIO block made good contact, but I reapplied thermal paste. I'm also aware that my case has some airflow limitations (tempered glass in front of intake fans with a gap). Removing it and using a ceiling fan helped a bit, though it still affects cooling. I'm worried about whether the case design is limiting airflow enough for this setup, especially since my current specs are listed as R7 3700X. I'm considering downgrading to a cooler CPU like the Ryzen 7 5700X, applying an early-access BIOS update, or improving airflow by tweaking fan curves or swapping out fans. Regarding Windows updates, the PC still works, but it's quite annoying to have to restart for posting and experience random fan speeds at idle (1.5-2K RPM). Before updating the BIOS, I tested the GPU with the new PSU and got no issues, though I only booted once before. After the update, the CPU light came back up. My main goal is to avoid replacing the motherboard after it's been damaged from overheating. Your thoughts would really help ease my concerns.
NVIDIA suggests a power of 750W. The 3080s were recognized for their significant voltage fluctuations.
Initial experience with these tools. 10 cores used. R9 5900X tested on Cinebench.CSV.
It’s actually quite unusual how I’ve seen Hwinfo. The only thing I can mention is 85°C on the VRMs after just 10 minutes in Cinebench. It seems there might be more powerful programs than Cinebench, and your GPU isn’t overheating the case. Your build has limited airflow, a glass panel between the fans, and average cooling fans—so you likely have some VRM cooling, though it doesn’t fully explain why the PC doesn’t power on right away. Try running a game next; that will test both CPU and GPU and show you the real temps. Then share the hardware info screenshots.
More sensors would help if you reach the bottom buttons, but from what I see here it seems okay.
Updated here recently. A couple of days ago, after returning to work and editing photos with Photoshop, my computer crashed, showing a black screen and CPU light. After rebooting, everything worked normally. Recently, I’ve been putting my PC into sleep mode, and it starts up perfectly without any issues.
I've been using my 5800x3D on a B350 board for a while now and everything is working smoothly... the chipsets aren't really limiting performance unless they're poorly made. It's more about having extra features, higher specs, and better value—kind of like RAM handling its role well on Ryzen systems, but sometimes things can get unstable!
