Hey there, welcome to Ryzen! I’m new here and just got my 5800X and Rog Strix B550. I previously owned an i9 10900 and a B560-E, and I’ve had around 80°C temps in Warzone with the 10900 before. Now, my 5800X is running at about 80-83°C in the same game while D.O.C.P. is on, PBO limits are off, and Curve optimizer is enabled for all cores with a negative number of 10. I tried 30 and 25°C but faced crashes and dropped FPS. When the PC starts up, I notice a brief spike to around 80°C. That’s a bit concerning since it feels hotter than a 14nm 10-core i9. I’m also worried about the water pump speed—my BIOS shows it’s at 4500 RPM. I have a Corsair H100i Pro XT RGB 240mm liquid cooler, and the case door is open. My other specs include a 1080p monitor (EVGA XC3 Ultra, 3070, 16GB DDR4, 3600Mhz, CL18 dual), and I use Deepcool Z10 thermal paste. What’s your take?
Compact transistor arrangement positions it among the most sought-after chips today. Be cautious if performance drops at high temperatures—this device is quite sensitive. For optimal results, invest in the highest-end AIO available or design a tailored loop solution.
Everything looks fine in the long run. But I usually only notice 80s performance during an all-core stress test or benchmark. It’s uncommon to see over 65c under gaming conditions at 3840x1600. Can you clarify what you’re observing about temperature and all core clock speeds while running Cinebench R23? Also, what score appears for the multicore test? That should give us a quick indication if there’s an issue. I use an EK 360 AIO and perform per-core undervolting with the curve optimizer, though it can be time-consuming with corecycler. A Corsair 240 is fine for that setup, but I wouldn’t recommend it with a 5800x. Running one CCX with all eight cores active generates significant heat, as mentioned by @Guest 5150.
This conversation with Robert Hallock (Technical Marketing at AMD) can also ease some worries. When switching from an old Intel chip to a Ryzen 5000, it's important to adjust your mindset about what is considered "too hot." You can find more insights at the provided link.
Zen 3 offers significant thermal resistance, meaning even with modest power usage around 100W, the processor tends to overheat compared to a modern 10th gen Intel CPU drawing 200W. PBO typically forces the CPU to operate near 80-85°C under most workloads, adjusting voltage and frequency to stay within safe limits. This explains why Ryzen benchmark tests often focus on clock speed rather than actual temperatures.
If this matches the setup from the 80s when Windows loads, I’d think thermal paste between the pump plate and CPU might be the problem. My 5900X uses air cooling with six 120W fans plus a Scythe Mugen 5 and an extra 120W. Temperatures range from 38°C to 42°C idle, 57°C to 65°C under moderate load, peaking at 70°C–72°C during heavy use, and up to 76°C when PBO is off or 87°C with PBO on. The safe limit for 5800X, 5900X, and 5950X is 90°C. If you’re reaching 80°C just during Windows load, something’s off. My system stays around 40–42°C after a cold start. I doubt liquid cooling works here, but checking with an IR thermometer or feeling the loop could reveal air gaps blocking coolant flow. Edited June 11, 2022 by An0maly_76
I have two intake fans and three exhausts, which include water cooler fans. Also, as mentioned earlier, my case's door is open.
