Your Ryzen 9950X3D is experiencing high temperatures when not in use - (New Build)
Hey there! I just completed setting up my first PC, but I'm seeing some weird behavior. When idle, my CPU stays around 55°C, but during a Cinebench test it spikes to 95°C right away. I have a Corsair iCUE LINK TITAN 360 RX AIO. Could this be the issue? I noticed the coolant temperature stays steady near 33°C at high temps. My other machine has an Asus ROG Strix X870f with its AI tuner on auto, and it seems similar. Also, I made sure to remove any plastic contacts between the AIO and CPU—no problems there. Let me know what you think! Thanks!
Ai Overclock is garbage; it's probably pumping too much voltage into the CPU. That 360mm AIO should be able to handle a 9950X3D, unless it's faulty. Check the pump and fan speeds. PBO enabled? Since it's a brand new build. I'd disable any overclock and just run the system at stock for now. Enable EXPO and make sure then entire system works properly first, temperatures are okay, etc, before jumping into overclocking anything.
It's quite surprising that 95 degrees is anticipated with a 360mm AIO. In one of the most recent videos, Linus tested a new threadripper using a comparable AIO. It rarely reached those temperatures and only approached them after pushing it to its limits. For troubleshooting, I’d verify there’s sufficient thermal paste on the CPU, ensure the screws holding the copper plate are tight, and confirm the pump is running smoothly with heat dissipating through the radiator.
