If your asking how you work a fan, that's why they have manuals for them.
FAn works by current
Yes, if the fan is designed to work on DC voltage, otherwise no.
The motor of a fan works because of electromagnets, and electromagnets do work in vaccum so the fan will also work in vaccum.But, the fan will not cause any flow of anything because there is nothing to flow.
The fan motor has failed and will need replaced.
radiator fan relay
check the fan switch.
No. A fan needs to be plugged into electricity to work, but it does not have a charger.
Of course the electric fan will work.
The fan will work - but it will spin constantly - as it would have no data to rely on to regulate the temperature of the CPU.
Check your radiator fan switch and your fan switch coolant sensor .
A fan helps people cool down from a hot day.
