In this regard, what is the function of system fan?
The role of the computer fan is to pull cooler air into the computer to cool the hot circuitry, particularly the CPU. In a desktop the fan is typically a part of the power supply and draws air through it, helping to keep that part of the computer cool.
Beside above, what is the difference between a case fan and a CPU fan? There is a difference in case fans and cooler fans and that's static pressure. A case fan doesn't have to fight much resistance since its pushing thru a thin case grill while a CPU cooler family has to push thru a heatsink.
Keeping this in view, do you need a system fan?
Since the power put into a computer is pretty much all converted to heat, it means older computers run cooler / need less air flow. This is why your newer computer requires a system fan, but your older computer does not. It simply doesn't need as much cooling.
What is System fan failure?
A “System Fan Failure, System Fan 1 Failure, or Error: CPU Fan Failed” message and boot-up screen means that a computer is having issues connecting to or monitoring a system fan. ERROR: CPU Fan Has Failed! PC will automatically power down in a few seconds. Service the PC immediately to prevent damage to the PC.
