The CPU cooler isn't functioning correctly, which causes the computer to shut down.
I'm new to assembling a PC and everything seems fine except the CPU fan which switches on and off. The system boots but can't install Windows yet, and it shuts down after a short time due to overheating. Everything else works, except for this issue. Removing the CPU from the power supply on the motherboard makes the fan operate normally, which suggests the problem lies elsewhere. I'm using the original fan that came with the CPU. My setup includes: CPU – Ryzen 5 5600X, GPU – Nvidia GTX 1650, RAM – 2x8GB Kingston Fury DDR4, Storage – 256GB M.2 SSD (Patriot P300 1TB), M.2 SSD – Kingston NV2, Case – Antec C5 ARGB.
The CPU cooler is connected to the CPU fan header properly. Test another fan to see if it also stops, indicating a potential issue. If only the stock cooler spins normally, the one you have is faulty and needs replacement. Avoid powering up the system using the CPU power connector while it's unplugged from the board.
The CPU fan is properly linked to the cpu_fan header. I tested another fan and it performed fine, but I remain unsure why it worked without the PSU connected to the CPU. I haven’t tried it again as suggested. I own a Peerless Assassin 120 ES that I haven’t opened yet since I planned to return it, but I’m curious about trying it out. Would you recommend it? Also, if you have alternative options without using that additional heat sink, please share them, as it seems the stock fan is functioning well.
If a different fan functions properly while the stock cooler does not, the issue likely lies with that specific fan. I've encountered this repeatedly before—it's usually a defective fan in the AMD stock cooler, and you should replace the cooler. I recommend trying the Thermalright model, especially if you already own one. You can return it even if it's opened; the worst outcome is repeating the same problem, pushing us further into troubleshooting. In the best scenario, it works and you can safely use it. It's still a superior cooler compared to the stock version. Also, avoid running the system without connecting the CPU power connector—it shouldn't have been a known issue that you hadn't verified.
Everything functioned perfectly, thank you very much for your assistance! The image setup below is ready.
