How to Connect Case Fans to Power Supply
Motherboards have a limited enumerate of fan headers. Sometimes the number of fan headers is way lower than the amount of CPU fans you wear your subject. So, on the nose, 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 dual fans to personify connected to a single fan header or go for a Fan Hub that requires a tell power issue. Be warned, however, that most headers are limited in terms of how much power they can supplying. A fan header typically has a 1 amp military rank.
When using a Y splitter two CPU fans is generally alright for a single rooter header. Three CPU fans can start to drive the limit of the power a single fan header can supply.
It is quite important to check the fans' amperage since it will be the determining factor happening how many fans you sack actually trial off the motherboard and the splitter.
For example, you give notice only bleed 2 0.5A fans while four wouldn't exist an issue for 0.25A fans if your fan head is actually rated at 1 Amp.
A workaround for higher amps CPU fans would be to get a PC lover hub that can draw power directly from the power cater unit (PSU) and thereby, lifting the amperage restrictions.
In the chase text we will explore this topic far.
What is a FAN Header?
Quite an just, Fan Headers are terminals found on your motherboard where you plug your many PC cooling fans. They operate and monitor the fans of your Microcomputer.
Types of Fan Headers
There are triplet types of Fan Headers that you can receive happening the motherboard:
- CPU Fan Coping: For connecting the CPU Fan to.
- System Fan Header: For connecting PC/Case Fans (in-chief for the purpose of this article).
- Power Fan Header: Used for monitoring the Fan of the Power Supply Unit. Your PSU needs to have the monitoring cable for this heading to shape.
The System Fan Header is the ONLY case of coping that is ideal for case fans, splitters and PC fan hubs.

Can You Use CPU Lover Header and King Fan Header for Case Fans
Yes, you can use the CPU Fan Coping by rending it if you are seriously short connected sufficient System Fan Header.
You can also use the Power Fan Head, but this lintel does not provide any electric potential ascendence. The fans connected to this header will run for at full 100% capacity all the time.
3 Pin vs 4 Pin System Fan Headers
Most modern motherboards offer 4 pin system headers.
The difference betwixt a 4 immobilise and 3 pin system header is that the onetime supports PWM Instance Fans, whereas, as the latter only supports DC Case FANs.

Determining the Number of Fan Headers Your Motherboard Has
You can bump KO'd the number of Fan headers and their typewrite aside looking at your motherboard physically or by reading the manual:
The motherboard above only has ii System Devotee Headers. Therefore, you have more 2 case fans that you need to install, you will certainly demand a rail-splitter.

Knowing the Difference Between D.C. and PWM Fans
There are two types of Microcomputer fans that you can purchase:
- DC Fans
- PWM Fans
D.C. fans have 3 pins. These have inferior hasten control. Often low powered CPU fans are DC fans.
PWM (Pulse Width Modulation) fans enjoyment 4 pins. They have a better cannonball along control and are keen for minimizing noise.
While there is a list of aspects differentiating the two, the important points to remember between DC and PWM fans for the purpose of this article is that former requires 3 pin cope, whereas, the last mentioned requires a 4 pin header.

How to Plug in Extra Fans to Motherboard?
At that place are cardinal briny slipway to connect extra fans to your motherboard:
- Using a Y Fan Header Splitter
- Using a PC Fan Hub
1. Using a Y Fan Header Splitter
A winnow header splitter is the simplest and the cheapest way to connect more fans to your motherboard header. The number of fans that can be connected via a rail-splitter is contingent happening the amperage of the fans as fountainhead as that of the motherboard header. A motherboard devotee cope is unremarkably rated at 1 Ampere.
For refuge and performance chokepoint reasons, you should NOT reach the 1 Ampere mark when adding improving the military rank of whol of your fans connecting to a single fan header.
And so for instance if you have 2 x 0.4A fans associated to a 2-way splitter, you should have no issues. However, if you have 3 x 0.4A fans connected to a single motherboard fan header, then that is NOT nonpareil. Information technology is in point of fact a safety concern.
Setting up the Rooter Coping Splitter
The setup is very straight forward. The splitter's female destruction goes into the fan coping 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 and so happening). Needless to state, the pricing scales with the number of ends. But broadly they are super cheap.
All splitters are fashioned to connect to both 4 pin PWM and 3 pin DC fans.
Control on Splitters – NOT Individually Dominated
Splitters frequently have a ace swiftness control only. In other words, the cannonball along one overlord Fan will dictate the hotfoot of the rest of the well-connected PC fans.
You cannot solidification the speed of apiece fan individually. The motherboards sees all the fans connected to the splitter Eastern Samoa a sui generis entity.

2. Using a PC Fan Hub – For a Huge Number of FANs
Another way of life to connect multiple fans to your motherboard WITHOUT having to concern about power draw is to use a PC Buff Hub.
The beauty about PC Sports fan Hubs is that they are not pocket-sized to the 1 Ampere rating of the motherboard rooter headers. They draw power DIRECTLY from the Power Supply Unit exploitation the 15 pin SATA power cables.
American Samoa much, you can set u multiple high powered fans without having to worry about overloading the motherboard buff header.
Stage setting up the Fan Hub
Mount up the Fan Hub is also quite straight forward. It requires one SATA power connection from the PSU and one 3/4 pin connection from the motherboard head to the Sports fan hub.
The female terminate of the Fan Hub connects to the motherboard which then branches into several male headers for you to connect Fans to.
A Fan Hub put up typically connect upto 10 fans both 3 and 4 pin PWM or DC fans.
The PC Fan Hubs are virtually equally cheap as the rooter splitters we saw above. However, they Doctor of Osteopathy require an extra power supply connective. Consequently make a point you have a meagre SATA connective.
More dear offerings come with baked-in RGB accountant, which RGB enthusiasts may actually consider.
You bum place the Fan Hubs inside the case. Most come with adhesive tape operating room magnet that can live accustomed attach these to the case.
Control on Fan Hubs – NOT Individually Controlled
Look-alike the Y rooter head splitters we saw above, the fans connected to the Fan Hubs are also NOT individually controlled.
Essentially, combined Rooter abutting to the master header sets the focal ratio for the rest of the fans.
Molex Version of the Rooter Hub
Just in case if you are victimization old school Power Supply Unit with Molex connectors instead of SATA connecter, you can grow a Molex Fan Hub:
Winnow Hub With Available RGB
If you are a fan of RGB and if you have an Available RGB header on your motherboard, and then you rump find a 2-in-1 Fan+ARGB Hub as well.
Addressable RGB au fon substance that the color of the LED happening the fans can be controlled.
Again, you Doctor of Osteopathy pauperism to have an Addressable RGB header for this hub to work. Essentially, with this header, you can have upto 6 PC cans connected with the ability to change their color.
The colors cannot be changed individually for each fan, though.

Final Words
As farthermost as how to connect extra fans to motherboard goes, there are deuce basic ways that we covered in a higher place.
If this does not fit you, then in that location is a third way to add fans to your PC but that does not involve your motherboard. Essentially, you can use 3 pin to Molex adapters that can link directly to the Power Provision Unit bypassing the motherboard.
Even so, this method gives you no more hold in over the fans and does not provide you with any monitoring capability.
