Temperature changes during operation Issue with overheating in Ryzen 3000
The readings from your Smart Fan 5 Software by Gigabyte can indeed display rapid CPU temperature changes, fluctuating up and down by roughly 10°C within seconds. This behavior might be normal for your setup. Many users report similar issues, yet no clear solution appears. Your experience sounds frustrating because the fan speeds spike temporarily to maintain cooling, leading to noise and potentially higher temperatures during those brief bursts. Since your system runs at a stable idle temperature of 50°C–65°C and the default fan curves become much more aggressive, it could affect performance. You're right to be cautious about pushing fans too hard without knowing the long-term impact on your CPU health. With a high-performance air cooler and a case rated for good thermal efficiency, you might be able to manage this without drastic adjustments.
Ah ok like that. Sorry, but you souldve put that in there. Now i look silly.
They operate better at lower temperatures. My system is now at 56°C with background games running, but it still reaches around 70°C during heavy stress tests. I adjusted the fan settings to increase speed gradually above 71°C and kept it steady between 650-700rpm when cooler.
Based on what I've observed and learned, the temperature changes are linked to the boosting technology. Keeping an eye on your cores reveals they keep fluctuating repeatedly. The spikes happen when the processor switches from idle to maximum boost mode. But once you apply any workload, the temperatures tend to settle quickly.
I've checked everything mentioned and agree with the observations. I adjusted my fan curve according to Jeppes' recommendations, but it might not be ideal. At low loads, the CPU tends to run hotter than expected, even when idle with light software. When I tried to see the throttling point, turning off the fans didn't stop the temperature drop. It seems the readings could be off or the fan speed isn't that important until heavy loads are applied. The temps are still unusual, especially with a 3800X processor.
