Can I run fan without capacitor?
You can enjoy your fan without a capacitor if you give your fan a little more pushed with your hand when it starts. It will work normally. The capacitor is needed to start the fan creating a phase change in the electric motor field. It is not practical to remove the fan capacitor in motion, so we leave it there.
Can I run a 12v DC motor on 18v?
Since 12V lead batteries were originally designed for cars, there are many things that work that way. 18V would be risky, I wouldn't try to connect a 12V device on an 18V battery. But if you have 18V for any reason, you can still use a DC-DC converter.
Can I use a 19v power supply on a 12v?
19V is usually going to fry any device that has been designed to work at 12V (especially consumer products). And although it is not very likely that it might even catch fire. For an AC adapter to work, you will need one with exact voltage (12V) and a current rating equal to or higher (1.5A or more).
Can I connect chassis fan to AIO pump?
See more Will a housing fan be connected to the AIOPUMP connector? The AIO pump is designed for a water cooling system, probably with the EXT-FAN (sensors). CHASIS-FAN should be sufficient. You can also use fans operating at 12V at a continuous (high) speed.
Can I use a 12v coil on a 6v system?
You can run a 12 volt 1.5 ohm coil in a 6 volt car without ballast resistance and it will work very well. About 12 12 rolls of 12 volts read about 3 ohms and actually can only be used in a 12 volt car. The spark of this 12 volt coil when used in a 6 volt car will be very low.
