You're dealing with a serious cooling issue on your Ryzen 9 3900X. It's definitely frustrating when the system struggles to stay cool under load. Based on what you've shared, it sounds like the BIOS might be corrupted or there could be a hardware fault. The temperature readings are rising quickly, and the shutdown after reaching high temps is concerning. You mentioned a recent BIOS corruption during an update, which could explain the problem. It might help to try a factory reset or reinstalling the BIOS from the manufacturer's website. Also, ensure your cooling solution (like the Corsair H115i) is functioning properly and not overheating under load. If the issue persists after these steps, consider reaching out to ASUS support for further diagnosis.
It seems like the pump isn't functioning properly or is misaligned. The key factors to evaluate are if the pump is missing, improperly positioned, or if the filter is blocked by debris. Verify proper alignment and clean the filter. If problems persist, the pump likely needs replacement. Also confirm the pump cable connects to the CPU fan or AIO PUMP header on the motherboard, not an arbitrary fan port.
Your voltage settings tend to be lower than ideal. The latest Ryzen models prefer moderate voltages, and your motherboard might already be optimized for them. My Ssus board even reached 1.4V on my CPU, which isn’t suitable for Zen 2 chips. Skip iCue for temperature readings—use HardwareInfo instead.
I just changed my whole setup from an i7 6700k and didn’t run into any issues with that setup. The radiator is clean and the thermal paste is applied. It could still be the pump, since the Ryzen tends to generate more heat compared to the Intel CPU. I plan to install the standard Wraith Prism cooler. If it helps lower the temperature further, that would confirm my guess.
The voltages are fluctuating a lot. I recall it rising from around .9 to 1.4, which is definitely unusual. I’m not sure how to explain it, but it looks off. I’ll need to look up instructions on how to configure it and what settings to apply. I was also checking the iCue software to see if it can provide liquid temperature data. Meanwhile, both HWMonitor and the BIOS reported temperatures above 85 degrees. Also, I can’t boot atm because it’s showing a CPU overheat warning. Warning.
Feel the pipes on the AIO. The line leading from my CPU (a 3900x) feels warm, whereas the pipe going to the CPU remains cool—this helps confirm if liquid is moving between the AIO and the CPU. It might not be enough paste or it could be improper seating if the pump isn’t working well. I own an H100i and my temperatures are around 74°C even when the pump is on. Keep in mind that it’s running at full power with all 24 cores active during folding... I also noticed this CPU generates a lot of heat, so Ryzen Master would spike to over 70°C just by launching a program—then drop back down to 40-45°C when idle. Running anything heavy causes a big temperature rise.
Avoid using hwmonitor first. Instead, run hwinfo64. This processor has double the density compared to your previous setup. It will generate more heat. If it had the same number of threads, it would be significantly cooler. H10xx series are okay (i) they're just not up to the job, though there are air coolers that perform similarly. Finally, this machine should be throttled to 95°C, but everything needs to run at auto. The optimal temperature is around 115°C. Try not to stress test it until you resolve the cooling problem. Good luck and have fun!
Thank you. No need to worry about stress testing it at the moment. It reaches 95°C in one minute, which prevents booting. I’ll keep going and do my best.
Make sure the cooler is securely fastened. If the water block slides easily with little effort, the mount isn’t tight enough. It’s fine—just verify the cooler pump and pressure settings.
