Wrap the soldered wires with electrical tape. Make sure all exposed wires are covered with the tape. Attach a
9-volt battery to the snap connector
to provide power to the fan. You can also wire the end of a USB connector cable to the fan to provide power from your computer’s USB port.
How do I connect my CPU fan to my power supply?
There are two common ways fans connect directly to a power supply. Either using
a standard 4 pin power connector from the power supply
, or by using an adapter board that converts the standard power supply connector to a motherboard style pin header connector.

the fan is clogged with dust
, wires might get stuck in the fan or the fan does not get enough energy supply to spin. Getting rid of these causes might get your CPU fan up and running again.
Does the CPU fan connect to the power supply?
Champion. Like 007agentHP said, connecting the cpu cooler fan
directly to the power supply will just make it run full speed
. There’s no real downside in terms of temps, only in noise maybe.
How long will a computer fan run on a 9V battery?
It will probably run at about 3/4 the speed and draw about 3/4 the current (rough estimate) so around 100mA. Looking at a typical datasheet for an alkaline 9V battery, we can see the capacity will be perhaps 350mAh (down to 4.8V) so it might work for
3-5 hours
, as the current will drop as the battery discharges.
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
.
How long will a computer fan run on a 12v battery?
Your 30 watt fan will draw about 2.5 amps at 12 volts (2.5 times 12 is 30). Assuming 90% efficiency from the inverter means that the inverter will draw 2.5/. 9, or 2.78 amps. A 50 Ahr battery will last
50/2.78 or 18 hours
.
Should radiator fan turn on when AC is on?
Both radiator fans should always run when the AC compressor is engaged. To check the temperature at which the fan comes on, turn the A/C off and keep the engine running until it reaches normal operating temperature. Most fans should come on when the coolant reaches
about 200 to 230 degrees
.
Is an electric fan better than a clutch fan?
When compared to an electric fan,
fan clutches are quite inefficient
. … The benefits of a Thermatic Fan lay in its ability to provide constant air flow, improved fuel economy, better air-conditioning performance, cooler engine running and increased engine power.
Is it OK if my computer gets hot?
Heat is the deadly enemy of electronic components. In
extreme cases the computer will crash if it gets too hot
. Even if it doesn’t crash, overheating drastically shortens the life of components such as processors and hard drives.
