Explanation

A CPU fan RPM of 0 means the fan is completely stopped and not spinning. Without active airflow from the CPU fan, the processor will overheat rapidly, and the motherboard's thermal protection will trigger an automatic shutdown to prevent hardware damage - which directly explains the random shutdowns. A hard drive temperature of 30°C is within the normal safe range. A power supply providing +12V and +5V rails is operating correctly. One physical processor is the standard configuration for most desktop systems. The only anomaly indicating a problem is the non-functional CPU fan.
