CPU fan operates at full speed during startup.
Hello, I see you're experiencing some unusual behavior with your Ryzen 2700X setup. It sounds like the fan might be responding to something unexpected during startup. Since you're using stock thermal paste and haven't overclocked, the issue could be related to power delivery or a hardware quirk. The sudden high-speed fan activation upon turning on could indicate a power management event or a loose connection. The Ethernet cable disconnection causing shutdowns might point to a network-related fault. Consider checking the power supply stability, ensuring all cables are securely connected, and monitoring temperatures closely. If the problem persists, a hardware diagnostic might be necessary.
I recommend considering your options carefully. Here are the steps to follow:
1. Gather all necessary information.
2. Evaluate each suggestion based on relevance and feasibility.
3. Implement the best choice while keeping risks in mind.
4. Monitor outcomes and adjust as needed.
Let me know if you'd like more details!
Sorry but I'm facing a similar issue. My Corsair case had DC-controlled fans, not PWM. They would spin up or down without any clear reason. Possibly the motherboard wasn't delivering a stable DC signal, or maybe the fans themselves were faulty. I'm not certain. I swapped them for PWM-compatible ones and they run smoothly now. A steady hum that's easy to ignore is much better than random spinning. The PWM fans are also quieter overall.
I run the stock cooler with my Ryzen 5 3600 without any issues. I checked the BIOS settings, adjusted the fan curve, and enabled PWM control. I set the CPU fan to start at around 30% during startup, ramping up to about 40°C. Regarding the Ethernet cable problem, it seems like a motherboard issue rather than a shutdown or Windows process problem. When the cable is unplugged, the PC shuts down immediately, which suggests the hardware itself is failing.
Thanks a lot, I'll look into the PWM control. Second point: it just turns it off without any notice.
