It might be a bad power supply that only sends the correct voltage type to run a fan but not a mother Bord or hard drive.
You cannot, the CPU automatically runs when it needs to be cooled down or is processing large data. You can however buy another fan, install it to your computer, and make it run whenever the computer is on.

Check the fuse and the connections first. If the fuse and connections are good, then turn on the A/C. If the fan does not run, then apply 12 volts directly to the fan. If it still does not run it is defective. If it runs then the thermal relay is defective and needs replacing.
the computer will freeze or the fan will run automatically!
If the fan does not run, that is probably why it overheats.
If the relay is good and the fan is getting power and groun, then the fan motor is bad.
With many cars now days, the fan may continue to run after the car is shut off, or they may even start and run for a while after the car is shut off. An engine will actually get hotter for a short time after being shut off. Sometimes that will trigger a sensor to turn on the cooling fan. If it continually runs after being shut off, it could be a faulty temperature sensor, or a faulty fan relay, or even a bad computer.
No If the computer runs faster then it runs faster not slower
the let the engines run hoter to get better gas millage. i put a toggle switch on the fan so i can cool it down cause i dont really like it running too hot
It may run cooler, but this depends on if your radiator fan has a thermostat controlled temperature gauge or if your fan is mechanical. A mechanical fan has a fan belt attached and runs when the engine runs.
Yes
The most common reason for and electric fan not to run is a disconnected wire. Make sure all of the wires are connected and not corroded.
