Powering 12V fans via a wall socket:
To power our 12V fans via a wall socket, the Noctua NV-PS1 power supply can be used. This compact power supply supports both 230V and 115V input and comes with connectors for EU, US, and UK type sockets. Fans can easily be connected as the power supply comes with a NA-AC10 barrel to fan connector.
Powering 5V fans via a wall socket:
To power our 5V fans using a regular power outlet, you will need a customary USB power supply or power bank (or any other 5V DC power source with a USB port, such as laptops etc.).
We include an NA-AC7 USB power cable with some 5V fans, and you will only need an additional power supply to power one of these fans via USB. Please check the fan's scope of delivery to verify that a USB cable is included.
When powering a 5V fan via USB, the fan will run at maximum speed, and it will not be possible to adjust the fan speed.
If you would like to adjust the fan speed, we would recommend combining a 5V PWM fan with an NA-FC1 fan controller. (Please ensure that you have selected a PWM fan model, as non-PWM fans cannot be controlled with the NA-FC1.) This way, you can take advantage of the fan's full RPM range by adjusting the knob on the controller. The setup is very straight-forward: To enable speed control, simply connect the NA-FC1 between the fan(s) and your power source.
USB 5V PWM fans with NA-AC7:
200mm: NF-A20 5V PWM
140mm: NF-A14 5V PWM
120mm: NF-A12x25 5V PWM, NF-F12 5V PWM
92mm: NF-A9 5V PWM
80mm: NF-A8 5V PWM
40mm: NF-A4x10 5V PWM
We don't recommend running a 24 Volt fan via your power outlet, as you could potentially need several adaptors to be able to connect fans properly to the 24V power supply. Therefore, we would recommend using a 5V fan via a 5V USB power supply or a 12V fan with an NV-PS1 power supply instead.
