Review your previous query about fan curve ideas for the Ryzen 9 9950X3D with the NH-D15 G2.
Hey there, I'm setting up a Ryzen 9 9950X3D with a Noctua NH-D15 G2 cooler. The case uses six fans—three intake and three exhaust—to manage heat. Under load temps are good, but when idle it gets warm (around 55°C). I'm experimenting with fan curves to balance performance and noise. Some advice suggests starting case fans at about 40% until the CPU reaches around 80°C, then increasing quickly to 90%. That’s a common idea, but I’m not sure if it’s optimal with so many fans running. Would you prefer a smooth ramp from 30–40% up to about 60°C, then gradual increases? Or keep fans low until the CPU is really hot and then crank them up? Any tips from others who have similar configurations? I’d love to avoid overheating while keeping things quiet. Thanks for any curves or experiences you can share!
The CPU isn't concerned with temperature extremes—whether it's 55°C or 90°C. For each AM5 setup I own or use, I run the fans at their maximum speed without any audible noise. At 94°C, I hit a sharp 100% fan speed. My overclocked 9800X3D only reaches +94°C during full loads and stays below 90°C in regular gaming or heavy tasks. All case fans are set to operate as quickly as possible while remaining quiet. That gives ample airflow without disturbance. I’ll sacrifice a bit of cooling capacity to maintain lower noise levels.
At 55°C idle or browsing, the AM5 My 7950X3D runs smoothly with minimal activity, even in 23°C conditions using an Arctic LF3 360 AIO.
It's a simple flat shape with no noticeable sound. It varies based on fan preferences. My CPU cooler runs at full speed at 94°C, while my case fans stay at 25% continuously.
You can design a tailored fan curve to extend its life. Keep the fan running at low speeds when it's quiet—like idling or browsing—and increase the speed during heavy use or gaming for better performance.
I mainly rely on my stock case fans: two 180mm fronts, three 140mm bottoms, and one 140mm rear, paired with an AK620 Digital CPU cooler. It’s not necessary to complicate things. This is the specific curve for my rear fan—it’s set high but doesn’t produce noticeable noise, making it a solid choice.
