How do I know what voltage my fan is?
You can first test for 5V and then 9V. Visually observe the fan and if it is not running fast then go for 12V. Do not exceed the 12V limit as most PC fans are rated for max 12V.
What voltage is a fan?
Voltage, Current, and Wattage
| AC FANS | FANS |
|---|---|
| Voltage Range: Higher voltage ratings above 100. Common | Voltage Range: Lower voltage ratings below 100. |
| AC voltages include 110, 115, 120, 220, 230, 240 | Common DC voltages include 3,5,12,24,48 |
How do you test a fan with a multimeter?
Test the first set of wires: The white wire is called the run wire. Take your multimeter and set it to ohms. Take the black multimeter standard test lead and touch the white wire with it. Touch and continue touching the white – brown wire with the red multimeter probe.

How can I check if my fan is working?
Look and Listen The fastest way to tell if your computer’s fan has stopped working is to visually inspect it. If it’s a desktop computer, you can usually see the fan rotating on the back of the case. If the fan is not moving, you must replace it immediately, before using your computer further.
How do you check a fan without a CPU?
Splendid. The power button on your case connects two pins on the motherboard, which then causes your power supply to come on. The motherboard won’t respond to the power button if there is no CPU installed. If you want to test a fan, any DC 12V supply can power it for you.
Are CPU fans 5v or 12v?
Case fans use 12v. The 5v is just for harddrives and optical drives. 4-pin Molex = yellow 12v power, red 5v power, both black are grounds. 3-pin fan connector = 12v power, RPM, ground (seen them use different color schemes, but only 12v power, no 5v).
