Purchased a 3600XT... Operates smoothly at 50°C idle, but experiences temperature jumps to 65°C every few seconds.
I've experienced some major issues with my new CPU. It arrived three days ago, and since then it's been running hot even when idle, with the fan working erratically—speeding up and slowing down constantly. I checked the temperatures, and the core clock is fluctuating wildly: jumping to 4.5Ghz every 10-20 seconds, then dropping back to 3.5-36Ghz. At full speed it reaches 65°C, while at lower speeds it drops to 50°C. This is happening during idle loads with only 1-4% usage. It doesn't make sense to me. I searched online for solutions but found no answers. Many people have given up, saying it's normal or suggesting a quieter fan to mask the noise. I don’t want this to continue.
I understand the cooler is installed correctly. I also experience typical temperatures during games. However, this doesn’t explain the connection to periodic and steady temperature increases.
The surrounding temperature plays a role too. What device were you employing to gauge the heat?
Examine closely using Ryzen Master. The 4.5Ghz boost applies only to individual or a few cores, while the rest remain idle. The elevated temperature mainly affects those specific cores. The temperature rise is completely typical. Indeed, this reflects Zen 2's characteristics. If you wish to avoid the fan continuously accelerating and decelerating, set up a custom fan profile—keeping the speed idle until temperatures reach 55-60°C. This ensures the fan activates only when the CPU is genuinely under stress.
Thanks! I'll modify the fan curve. Just got a higher-quality cooler: 😊
Start by running hwinfo64 to verify the temperatures. Then confirm whether the monitor's Ryzen readings are precise. Next, ask about your load temperatures—if they're within range, you can relax as idle temps aren't critical, only load temps matter.
