Add the new fan, link it to the fan header, and confirm completion.

No, the fans do not run or light up at all.

No, it does not power up when you disconnect the fans.

Did you verify every link? It’s possible you disconnected another connector from the MB during installation of the fan.

The CPU indicator is blinking and the power supply is toggling on and off. Everything appears intact.

Did you insert the connector into the right slot? Some motherboards have similar connectors, leading to a feedback loop that may halt the boot sequence. If needed, reposition the CPU.

No, the battery was inserted correctly. The CPU_FAN header is not blank.
