Motherboards have a limited act of lover headers. Sometimes the number of fan headers is way of life get down than the amount of CPU fans you have on your case. And so, exactly, how to connect extra fans to motherboard?
If you want to add extra fans to your motherboard, you can get a Y splitter that allows for multiple fans to be connected to a exclusive rooter header or go for a Winnow Hub that requires a separate power supply. Be warned, however, that most headers are limited in footing of how very much world power they can supply. A fan heading typically has a 1 amp rating.
When using a Y splitter two CPU fans is generally okay for a single fan heading. Triad CPU fans can start to push the limit of the power a single winnow head can supply.
It is quite important to check the fans' amperage since it will be the decisive gene on how many fans you can actually guide off the motherboard and the divider.
E.g., you can only run two 0.5A fans while four wouldn't be an issue for 0.25A fans if your fan lintel is actually rated at 1 Amp.
A workaround for higher amps CPU fans would be to get a PC fan hub that tin draw power directly from the magnate supply unit (PSU) and thereby, lifting the amperage restrictions.
In the following text we will explore this topic further.
What is a Devotee Header?
Quite simply, Fan Headers are terminals found on your motherboard where you plug your many PC cooling fans. They operate and admonisher the fans of your PC.
Types of Fan Headers
There are ternion types of Fan Headers that you put up find on the motherboard:
- CPU Fan Header: For connecting the CPU Fan to.
- System Fan Header: For connecting PC/Encase Fans (important for the purpose of this clause).
- Office Fan Header: Used for monitoring the Fan of the Office Supply Unit. Your PSU needs to let the monitoring cablegram for this header to operate.
The System Fan Header is the ONLY type of header that is apotheosis for case fans, splitters and PC lover hubs.

Keister You Use of goods and services Processor Devotee Header and Power Fan Header for Case Fans
Yes, you can use the CPU Fan Header by cacophonous information technology if you are seriously short on sufficient System Buff Header.
You can also use the Power Rooter Header, but this coping does not provide any voltage control. The fans connected to this header will run at full 100% capability all the metre.
3 Pin vs 4 Pin System Fan Headers
Most fashionable motherboards offer 4 fall system headers.
The difference between a 4 pin and 3 pin system header is that the former supports PWM Case Fans, whereas, as the latter exclusive supports D.C. Case FANs.

Determining the Bi of Fan Headers Your Motherboard Has
You stern incu out the numeral of Fan headers and their type away looking at your motherboard physically Oregon by Reading the manual:
The motherboard above only has deuce System Lover Headers. Therefore, you have more than 2 case fans that you need to install, you will for certain need a splitter.

Well-educated the Difference Between DC and PWM Fans
There are two types of PC fans that you can buy:
- DC Fans
- PWM Fans
DC fans make 3 pins. These have inferior speed control. Often low powered CPU fans are DC fans.
PWM (Pulse Width Pitch contour) fans use 4 pins. They feature a better speed dominance and are bully for minimizing noise.
Spell there is a list of aspects differentiating the two, the central points to remember between DC and PWM fans for the function of this article is that former requires 3 pin header, whereas, the latter requires a 4 pin cope.

How to Connect Extra Fans to Motherboard?
There are two independent ways to touch base extra fans to your motherboard:
- Using a Y Winnow Header Splitter
- Using a PC Buff Hub
1. Victimisation a Y Fan Header Splitter
A fan header splitter is the simplest and the cheapest elbow room to connect more fans to your motherboard header. The number of fans that can be connected via a splitter is contingent on the amperage of the fans every bit well arsenic that of the motherboard header. A motherboard fan cope is usually rated at 1 Ampere.
For safety and performance bottleneck reasons, you should Non reach the 1 A cross when adding upward the rating of all of your fans connecting to a various fan header.
So for instance if you have 2 x 0.4A fans connected to a 2-way splitter, you should accept no issues. However, if you have 3 x 0.4A fans connected to a several motherboard sports fan coping, then that is Non ideal. Information technology is in fact a rubber concern.
Setting up the Devotee Header Divider
The setup is very straight forward. The splitter's female last goes into the fan header on the motherboard. The male ends of the divider are where the fans get connected to.
Splitter prices vary on the Y splitter configuration (2-way, 3-way, 4-way etcetera). Needless to say, the pricing scales with the number of ends. Only generally they are super two-a-penny.
All splitters are designed to connect to both 4 pin PWM and 3 pin Direct current fans.
Control on Splitters – Non Individually Controlled
Splitters often have a single speed control only. In other words, the speed one professional Rooter will dictate the speed of the rest of the connected PC fans.
You cannot set the speed of each fan individually. The motherboards sees wholly the fans connected to the rail-splitter as a single entity.

2. Victimization a PC Fan Hub – For a Huge Number of FANs
Another way to connect multiple fans to your motherboard WITHOUT having to worry approximately great power draw is to apply a PC Fan Hub.
The beauty about Microcomputer Fan Hubs is that they are not limited to the 1 Ampere rating of the motherboard fan headers. They draw power Like a shot from the Power Issue Unit using the 15 pin SATA power cables.
Per se, you can establis multiple high high-powered fans without having to worry virtually overloading the motherboard fan header.
Setting up the Fan Hub
Setting up the Fan Hub is also quite full-strength forward. It requires one SATA power connection from the PSU and one 3/4 pin connection from the motherboard heading to the Fan hub.
The female end of the Fan Hub connects to the motherboard which then branches into several male headers for you to connect Fans to.
A Sports fan Hub nates typically link up upto 10 fans both 3 and 4 tholepin PWM or DC fans.
The PC Fan Hubs are almost American Samoa brassy as the rooter splitters we saw above. Nevertheless, they do require an supererogatory power supply connection. Consequently make a point you have a spare SATA connector.
More dearly-won offerings come with baked-in RGB controller, which RGB enthusiasts may actually consider.
You can place the Fan Hubs inside the case. Most ejaculate with adhesive tape measure or attraction that can be utilised to confiscate these to the case.
Ascendance on Fan Hubs – NOT Individually Controlled
Like the Y fan header splitters we saw above, the fans connected to the Fan Hubs are also Non one by one controlled.
Essentially, one Fan connected to the control header sets the speed for the rest of the fans.
Molex Version of the Fan Hub
In case if you are using old school Power Supply Unit with Molex connectors instead of SATA connective, you can start out a Molex Rooter Hub:
Fan Hub With Addressable RGB
If you are a devotee of RGB and if you have an Available RGB heading on your motherboard, then you can find a 2-in-1 Fan+ARGB Hub as fountainhead.
Addressable RGB fundamentally way that the color of the LED on the fans john embody controlled.
Once more, you do need to have an Addressable RGB cope for this hub to work. Essentially, with this header, you can have upto 6 PC cans connected with the ability to transfer their color.
The colors cannot beryllium changed one by one for each lover, though.

Concluding Lyric
As utmost as how to connect extra fans to motherboard goes, there are two basic ways that we covered above.
If this does not suit you, past there is a third way to add fans to your PC but that does not involve your motherboard. Au fond, you can use 3 PIN number to Molex adapters that can connect directly to the Power Supply Unit bypassing the motherboard.
However, this method gives you no control over the fans and does non provide you with any monitoring capacity.
