Computer Fan Header

The fan connector will have two guides 1 and these will need to line up with the tab 2 that is on the motherboard fan header.

Blower fan hose. There is no fan control. The three wire connectors are for small chassis fans with lower power consumption. Most fans have 3 wirespins.

Both axial and sometimes centrifugal blowersquirrel cage fans are used in computers. Next press down until the fan connector is fully connected to the motherboard header. Fan has a 3 pin power connector.

Chassis fan hub cpu cooling 10 port 12 v sata to fan header with 4 pin pwm controller efficient chassis adhesive computer cooling system dedicated supply from psu to link multiple points. Fans and on board fan headers are backwards compatible. A computer fan is any fan inside or attached to a computer case used for active coolingfans are used to draw cooler air into the case from the outside expel warm air from inside and move air across a heat sink to cool a particular component.

The fan will function normally no matter type of fan header is used. Computer fans commonly come in standard sizes and are powered. The port that the fan connects onto the motherboard is known as the fan header.

When using a 3 pin power connector with a 4 pin fan header the fan will always be on. Its recommended that the pump be connected to an alternative fan header on the motherboard such as system fan 1 chassisfan 1 or for newer motherboards a dedicated pump. Connect one adapter to cpu fan 1 and the other adapter to cpu fan 2.

Your cpu fan will likely have an option for a target temperature in degrees celsius and a minimum speed either in percentage or rpm. The cpu fan is usually supplied with a 3v or 5v from the psu power supply unit on laptops and 12v on desktops. Installing a 4 pin fan to the motherboard.

Four radiator fans via y splitters. The four wire connectors are for processor fans with higher power consumption. Then check the cpu cooler to ensure it is properly secured to the motherboard.

Basically this allows you to say keep my fan at x speed until the cpu reaches y degreesthen intelligently ramp up the fan to cool it down the hotter your cpu gets the faster your fan will spin. Get it as soon as thu sep 24. Connect the fan power lead on the cpu cooler to the cpu fan header on the motherboard.

Proper fan connector placement is shown in the figures below. One to supply the voltage red another is neutral black and the other is used to control the fan speed yellow. Connect one fan to cpu fan 1 and the other to cpu fan 2 opt.

A three wire fan connecting to a four pin fan header. If the cpu cooler has rgb led connect the bundled rgb cable to cpu cooler and the rgb header on the motherboard. There is no fan control.

When connecting a three wire fan to a four pin fan header the fan is always on. Refer to your motherboard user manual for the cpu fan header location.
