PSU or Mobo problem? Case fans remain active even when powered off.
PSU or Mobo problem? Case fans remain active even when powered off.
Hello. Recently I've encountered a problem where my case doesn't just stay on after shutdown, but actually speeds up to full capacity. It remains active until I turn the power button on the PSU. After that, everything stops completely once I shut it down. When I restart it through Windows, the issue resumes, returning to normal. I also disassembled the machine to check for obvious faults, cleaned it thoroughly, but the problem persisted. My research suggests a motherboard or power supply might be the culprit. I'm planning to post on a forum for further help.
The first three intake fans pass through a hub linked to the motherboard. The remaining two fans along with the CPU fan connect straight to the motherboard.
