Can you plug a fan into a USB header?
Can you plug a fan into a USB header?
CPU cooling fans should ALWAYS be plugged into the header that is specifically labeled “CPU Fan” and not “CPU Optional” or any other header.
What are the 3 pins on a computer fan?
A three pin connector is basically power (5/12 volt), ground, and signal. The signal wire measures how fast the fan is moving without any controls for the fan’s speed. With this type, fan speed is typically controlled by increasing or decreasing the voltage over the power wire.
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.
How do you power a 12V DC fan?
To power a DC fan, we feed the fan its rated voltage. For example, to power a 12VDC fan, we need to feed it 12 volts DC. This power can come from any DC voltage source, such as a DC power supply or even batteries. If using batteries, in order to get 12V output, you would have to place 8 ‘AA’ batteries in series.

Will a 4 pin fan work with a 3 pin connector?
Yes! PWM fans come with a 4-pin connectors for fully automatic speed control via your mainboard’s 4-pin PWM fan headers. Please note that 4-pin fans can also be connected to your mainboard’s 3-pin fan headers though.
Can you plug 3 pin fan into 4 pin?
Please Note: You can connect a 3 Pin Fan to a 3 Pin or 4 Pin header on the motherboard. The fan will function normally no matter type of fan header is used.
What is a 3 pin fan connector used for?
01 Mar 1998 3 Pin Fan connector used on the ATX Motherboard. 3 PIN IDC FEMALE at the fan and 3 PIN IDC MALE header at the motherboard. Pin Name Color 1 GND black 2 +12VDC or +5VDC red 3 Tachometric Signal yellow Notes Not all fans or motherboards control or power the fan assemblies the same way. Fans may be either 5 Volt DC or 12 Volt DC fans.
What type of power connector do I need for a fan?
Chassis and CPU fans may use either 3-pin or 4-pin power connectors. 3-pin connectors are usually used for the smaller chassis fans with lower power consumption. 4-pin connectors are usually used by CPU fans with higher power consumption. Fans and on-board fan headers are backwards compatible.
What is the correct fan connector placement for my Motherboard?
Proper fan connector placement is shown in the figures below: Fan has a 3-pin power connector; desktop board has a 4-pin fan header: Note: when using a 3-pin power connector with a 4-pin fan header, the fan will always be on; there is no fan control. Fan has a 4-pin power connector; desktop board has a 3-pin fan header:
How many pin IDC do I need for the fan?
3 PIN IDC FEMALE at the fan and 3 PIN IDC MALE header at the motherboard. Pin Name Color 1 GND black 2 +12VDC or +5VDC
