If your aim is to use the car fan (Running on DC (Direct Current)), to the house electricity (Which runs AC(Alternating Current)), you can achieve it by using a Power Converter. Since an AC power supply sends voltage in alternating waves, DC voltage will be lower once you convert it. As the components in your computer operate, they build up heat, which can lower performance and eventually damage the hardware if it goes unchecked. They are for use with the PC. Abbreviated as PS or P/S, a power supply or PSU (power supply unit) is a hardware component of a computer that supplies all other components with power.

The image shows an Antec True 330, a … Image of energy, electronics, adapter - 125235582 ex.) Use a small sharp knife, such as hobby knife, to cut the wire free of the plastic casing. I already figured out the necessary AC/DC Adapter to use to power two 80mm case fans- A 12V AC Adapter at 1000ma. The difference between 2-wire fans and 3-wire fans is the availability of feedback from the fan for closed-loop speed control. Older drives or fans may use a 4-pin Molex connector, with larger pins and a trapezoidal plug. If you see all possible combinations there would be exactly 27 combinations for you to try. 80mm computer fan that is thermally controlled. I learned that the white wire to the inner side of the cylindrical shaft is solely for the power adapter's use: it measures the voltage drop between the 19VDC, feeding this info back to the adapter.
