Control Case Fans Speed When Connected to Power Supply
Motherboards have a limited number of fan headers. Sometimes the number of winnow headers is way lower than the amount of CPU fans you have connected your case. Thusly, exactly, how to connect extra fans to motherboard?
If you wish to attention deficit disorder extra fans to your motherboard, you can get on a Y divider that allows for multiple fans to be connected to a single buff header or hope a Rooter Hub that requires a isolated power append. Embody warned, however, that most headers are limited in price of how much power they arse supply. A sports fan header typically has a 1 amp rating.
When using a Y splitter two CPU fans is generally okay for a single fan header. Three C.P.U. fans can outset to push the limit of the power a single fan header can supply.
Information technology is quite an important to impediment the fans' amperage since it will be the determining factor out on how many fans you can really run off the motherboard and the divider.
For instance, you can only run two 0.5A fans while four wouldn't be an issue for 0.25A fans if your fan header is actually rated at 1 A.
A workaround for higher amps CPU fans would represent to capture a PC fan hub that terminate get out power directly from the power supply unit (PSU) and thereby, lifting the amperage restrictions.
In the pursuit text we will explore this topic further.
What is a Sports fan Header?
Quite simply, Fan Headers are terminals found on your motherboard where you punch your numerous PC cooling fans. They control and monitor the fans of your PC.
Types of Fan Headers
At that place are three types of Fan Headers that you can observe on the motherboard:
- CPU Sports fan Header: For connecting the CPU Devotee to.
- System Fan Header: For conjunctive PC/Suit Fans (noteworthy for the purpose of this article).
- Power Buff Header: Secondhand for monitoring the Fan of the Major power Supply Building block. Your PSU needs to have the monitoring cable for this header to work.
The System Rooter Header is the ONLY type of header that is ideal for casing fans, splitters and PC winnow hubs.

Fundament You Use CPU Fan Header and Power Fan Header for Case Fans
Yes, you can use of goods and services the CPU Fan Heading by rending IT if you are in earnest short on decent System Fan Coping.
You can also use the Power Buff Header, merely this header does non provide any voltage control. The fans connected to this header will function at weighed down 100% capacitance all the time.
3 Pin vs 4 Pin System Winnow Headers
All but modern motherboards offer 4 pin system headers.
The difference between a 4 PIN number and 3 pin organization header is that the former supports PWM Case Fans, whereas, as the latter only supports DC Case FANs.

Determining the Number of Fan Headers Your Motherboard Has
You can discover out the number of Fan headers and their type by looking at at your motherboard physically or past reading the manual:
The motherboard above only has two System Rooter Headers. Consequently, you possess more than 2 suit fans that you necessitate to install, you will sure need a splitter.

Knowing the Difference 'tween DC and PWM Fans
There are two types of PC fans that you can buy out:
- DC Fans
- PWM Fans
DC fans have 3 pins. These have inferior speed control. Often low powered CPU fans are DC fans.
PWM (Pulse Width Inflection) fans use 4 pins. They have a improve hurry hold and are great 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 header, whereas, the latter requires a 4 pin coping.

How to Touch base Extra Fans to Motherboard?
There are two independent slipway to connect extra fans to your motherboard:
- Exploitation a Y Lover Cope Splitter
- Using a PC Buff Hub
1. Using a Y Fan Header Splitter
A winnow header splitter is the simplest and the cheapest way to connect many fans to your motherboard header. The number of fans that can be connected via a splitter is conditional the amperage of the fans as easily as that of the motherboard header. A motherboard rooter header is usually rated at 1 International ampere.
For safety and performance constriction reasons, you should NOT reach the 1 Ampere mark when adding up the rating of all of your fans connecting to a single fan header.
So for example if you birth 2 x 0.4A fans connected to a 2-way splitter, you should have no issues. However, if you experience 3 x 0.4A fans related to a exclusive motherboard fan coping, then that is NOT ideal. It is in fact a prophylactic concern.
Setting heavenward the Buff Coping Rail-splitter
The setup is very straight onwards. The splitter's female end goes into the fan lintel along the motherboard. The male ends of the splitter are where the fans get connected to.
Splitter prices motley on the Y divider configuration (2-way, 3-way, 4-manner etc.). Needless to say, the pricing scales with the number of ends. But generally they are super cheap.
All splitters are planned to connect to both 4 tholepin PWM and 3 pin DC fans.
Control happening Splitters – NOT Individually Dominated
Splitters often have a single speed control only. In other words, the speed one get over Fan volition dictate the speed of the rest of the connected PC fans.
You cannot set the speed of each fan severally. The motherboards sees all the fans connected to the splitter as a single entity.

2. Victimisation a PC Buff Hub – For a Huge Number of FANs
Another way to relate multiple fans to your motherboard WITHOUT having to vexation about power depict is to use a Personal computer Fan Hub.
The beauty about PC Lover Hubs is that they are not limited to the 1 Ampere rating of the motherboard fan headers. They draw index DIRECTLY from the Major power Supply Unit victimization the 15 trap SATA power cables.
Intrinsically, you can install multiple high powered fans without having to worry about overloading the motherboard fan header.
Setting up the Fan Hub
Setting improving the Fan Hub is also quite straight forward. IT requires one SATA tycoo connectedness from the PSU and incomparable 3/4 pin connection from the motherboard cope to the Fan hub.
The female last of the Buff Hub connects to the motherboard which and then branches into single virile headers for you to connect Fans to.
A Fan Hub can typically connect upto 10 fans both 3 and 4 pin PWM Oregon DC fans.
The Microcomputer Fan Hubs are almost as cheap as the buff splitters we saw above. However, they do require an extra ability supply connection. Thence take a leak sure you birth a spare SATA connector.
To a greater extent expensive offerings come with baked-in RGB restrainer, which RGB enthusiasts English hawthorn actually moot.
You can place the Devotee Hubs inside the case. Most come with adhesive record or magnet that can be used to seize these to the case.
Control on Fan Hubs – NOT Severally Priest-ridden
Wish the Y fan header splitters we power saw above, the fans wired to the Sports fan Hubs are also NOT individually controlled.
Au fond, one Winnow connected to the passe-partout header sets the swiftness for the rest on of the fans.
Molex Version of the Lover Hub
In case if you are exploitation old school Power Issue Unit with Molex connectors instead of SATA connector, you can get a Molex Fan Hub:
Fan Hub With Addressable RGB
If you are a fan of RGB and if you have an Addressable RGB header along your motherboard, then you buns find a 2-in-1 Sports fan+ARGB Hub as well.
Available RGB basically means that the color of the LED happening the fans give the sack be controlled.
Again, you coiffure need to have an Available RGB header for this hub to work. Fundamentally, with this header, you can have upto 6 PC cans wired with the power to change their color.
The colors cannot constitute changed individually for to each one fan, though.

Final Actor's line
As far as how to connect extra fans to motherboard goes, there are two basic ways that we covered above.
If this does not suit you, then thither is a third way to add fans to your PC but that does non involve your motherboard. Essentially, you can use 3 pin to Molex adapters that can connect directly to the Power Supply Unit bypassing the motherboard.
However, this method acting gives you no keep in line over the fans and does not provide you with any monitoring capability.
