Check Ryzen 3900x overheating issues. Find solutions to manage heat effectively.
Hey there, newcomers! Just starting here, so don’t worry too much. You’re using an Asus ROG Strix B550-I motherboard in a NZXT H1 case with the 140mm AIO and a 650W PSU. Your temps seem to spike during both idle and gaming—max around 76°C while gaming, and idle temps between 44-53°C. You’ve tried adjusting CPU voltage, setting it to 3.8GHz, disabling PBO, using a full fan curve, and even lowering voltage, but still can’t bring things down. Others suggest aiming for 32°C idle and 55°C gaming with this rig. You mentioned checking the Jayztwocents 3900x overclocking guide and that you’re worried about long-term CPU health from overheating. The UEFI bios update looks different now, which might affect settings. Your DOCP is enabled for normal RAM usage (3466MHz), but you’re concerned it could wear out the CPU faster. A screenshot of your HWinfo data showing idle temps over an hour is attached. Any tips or adjustments would be super helpful!
your temperatures are acceptable. the jayz2cent video claiming it runs at high voltages is incorrect; it actually operates with low current. this setup can cause higher voltage when under load. clearing the CMOS and adjusting the voltage limits won’t harm your CPU.
Consider testing with a demanding workload such as continuous Cinebench R20 for extended periods. Observe how temperatures rise. A tougher benchmark like prime95 can help gauge maximum heat output. If it stays below 95°C during the test, it’s acceptable. Running at 76°C for several minutes seems manageable, but lowering the voltage might be necessary to reach higher speeds safely. (*Note 4.2 might be too high; 4.1 should suffice.) The actual performance will depend on the chip's characteristics. Don’t rush to adjust settings without confirming stability first. A short initial run (about 10 minutes) of Cinebench is a good start to check for stability and performance trends before committing to higher frequencies.*
I performed a BIOS update focusing only on RAM configurations, adjusting the memory settings to 3466 and configuring the CPU voltage and ratio. No other changes were made. Should I run another flash? I’m not an expert, but it doesn’t seem essential. Regarding the undervolt reset, what adjustments would you suggest? Your concern about others achieving lower idle temps is understandable.
Adjust the undervoltage by eliminating it. Reset the CMOS since your CPU is functioning perfectly.
Hi j0nnicage, I have the same setup as yours and the same issue. What bothers me most is the temperatures—I did everything correctly, but I can't bring them down. I just ordered a rear fan bracket mod from Artesian Builds (https://artesianbuilds.com/case-mods-par.../222208020). I hope it helps. As you mentioned, other builds reach around 39°C in idle, but mine stays between 52-60°C. When I play games like The Tomb, it climbs to 65-69°C, which is great, but in idle it's not that good at all. Could you suggest a solution?
