How do I power the fan on my Raspberry Pi 4?
Connect the fan to the Pi Connect the fan’s red wire to GPIO pin 4 (5V) and the black wire to GPIO pin 6 (ground). The fan should receive power automatically when the Pi is booted. If you’d like your fan to only run when needed (based on Pi temperature), check out our Raspberry Pi fan controller guide.

How much power does a Raspberry Pi fan use?
When it’s running, the fan also draws 80 mA of power, continuously, so if you’re counting milliamps when supplying power to the Pi (e.g. when running off solar or battery), keep that in mind!
Does Raspberry Pi 4 need cooling fan?
The firmware update makes it so you don’t need a fan to use a Raspberry Pi 4 in a typical case anymore. The ICE Tower Cooling Fan lives up to its name; it cools the Pi 4 extremely well, but it is massive and requires some thought as to how to encase the Pi if you’re considering using it in the real world.
Does the Raspberry Pi 4 need a fan?
You will need a fan if you’re regularly using the Pi for more extended periods. Regardless of what tasks you perform with the Raspberry Pi 4 or for how long you’re usually using it; it is still best to install a fan considering the tiny board’s upgraded specs.
Can I control DC fan?
If you want to vary the speed of DC fans, the only option is to vary the input DC supply. The DC power supply can be reduced below 12 V for lower speeds. There are still limitations in the percentage decrease in the speed of DC fans.
Does a PI 4 need a fan?
How much power does a Raspberry Pi 4 use a month?
With a more power-hungry processor and the need for at least a 5-volt, 3-amp power adapter, the Pi 4 should be expected to consume more power than its predecessors.At idle, the Pi 4 B draws 3.4 watts, which is just 17% more than the 3 B+.
What happens when a Raspberry Pi overheats?
How Does Pi Deal with Overheating? A reported issue with Raspberry Pi can be overheating, with a resulting loss of performance, when the board is exposed to high temperatures. All electrical devices are qualified to a specific operating temperature range at which the device will work effectively.
Can You Power a fan on a Raspberry Pi 3?
You can not power a fan from the Pi’s GPIO. The GPIO are all 3V3 and only supply a few tens of milliamps at best (you are recommended to draw no more than 16mA from an individual GPIO). You can power a fan from a 5V power rail pin on the expansion header.
Can a GPIO be used to power a fan?
The GPIO are all 3V3 and only supply a few tens of milliamps at best (you are recommended to draw no more than 16mA from an individual GPIO). You can power a fan from a 5V power rail pin on the expansion header. You might be able to power a fan from a 3V3 power rail pin on the expansion header but that will depend on your Pi model.
What kind of pin do I need to power a fan?
You can power a fan from a 5V power rail pin on the expansion header. You might be able to power a fan from a 3V3 power rail pin on the expansion header but that will depend on your Pi model. Early Pis had very limited 3V3 power available.
What kind of fan should I get for my Pi 3?
The safest bet is to get a 5V fan and try it with 3.3V: it will almost certainly rotate at roughly half the RPM, which reduces the noise a lot. If it doesn’t work, or the airflow is not sufficient, you can still power it with 5V. Another option (that I personally use) is to get a 12V fan and power it with 5V.
