idle times don't really matter much—they depend more on your overall setup and fan configuration than precise measurements. My 5800x running at 40°C because I wasn't motivated to adjust the fan curve for my case fans; back then it was about 50% idle. Regarding load temperatures, they seem okay.
Operating around the mid-60s on an AM5 board is typical; these processors maintain higher voltage during light loads to remain responsive, which means temperatures don’t drop as much compared to older systems. Focus on maintaining stable temperatures across all cores—you’re well within safe limits. Adjusting the fan curve notably reduced idle temps to 30–40°C, a significant improvement for airflow. For even better efficiency, consider Eco mode or Curve Optimizer undervolt, which can cut another 5–10°C without affecting performance. Ensure your cooler is properly mounted and paste application is optimal; with NT-H2 + D15 you’re in good shape. Evaluate stability using sustained load tests via Cinebench or OCCT—keeping temps below 90°C is ideal. Your airflow adjustments have already positioned you at the optimal range for the 9950X3D.
You recently ran Talos Principle 2 for roughly an hour at full resolution, maintaining steady 90 fps. Your GPU handled the workload smoothly, peaking around 65°C, while your CPU remained stable near 75°C, suggesting a load between 60-75%.
The figures really support the performance. A 75C CPU handling 60–75% load fits perfectly with a 9950X3D, especially when matched with a 3080. GPU temperatures around 65°C are impressive. Maintaining 90 fps at 3440×1440 ultra shows both components are operating efficiently. It looks like your setup is optimized, with the fan curve and airflow adjustments making a difference.
Hello, I see you're revisiting an old discussion. I'm using a similar rig (9950X3D with NH-D15 G2 LBC) and sticking to stock configurations—around 50°C idle, 80°C load. Even though reviews claim these are standard temps, I suspect it's a bit too hot. I adjusted the Curve Optimizer to -25 and tweaked PBO, PPT to 170W, TDC to 120A, EDC to 180A. On workload, it's now around 70°C. Performance dropped slightly from ~200W to ~150W. In Cinebench, stock gave 41,478 points; after changes, I'm seeing 40,774. I'm not sure if these numbers are optimal, but it seems like a small improvement without major loss.
It mainly comes down to the room temperature. At around 20°C outside, I think 50 is quite high. Here, during midday, my room stays in the low 30s, which isn't uncommon for higher temperatures compared to others.
Hey, I’d feel like a big fat polar bear all the time, but I’m not one either. At work they keep the temperature above 75°F, and if I could just wear some underwear, I’d be fine. Now that it’s cooler outside, they turn up the heat. To be honest, most of the people I work with aren’t from here, so I get it a bit. It really hurts.
