How to connect extra fans to Motherboard

Cooling is very important in our PCs, whether it is the choice of heat sink for CPU as well as various wing connectors or the choice of radiator pumping motors for liquid cooling. In any case, it is relevant to distinguish between the fan connector on the motherboard.

In this article, we are discussing how to connect extra fans to Motherboard.

In fact, every 3 or 4-pin connector used to connect a fan or radiator to our PC’s motherboard had a specific function, each of which depended on the correct functioning of the system.

Nowadays, however, everything is more automated, with advanced telemetry and control systems that allow a greater number of configurations and, therefore, more possibilities for each connector. People are also curious about what driver we need for the motherboard.

In addition, each board includes a series of connectors, which are common in many cases, but in others, they may be specific to the model by adding a large number of them or copying others, so they are interesting to know more closely. :

Which fan connector to use?

The first element that cools the computer or computer is its central processing unit, which performs all the programs and integrates the various components and peripherals in an organized manner. Today we have processors that can go beyond 100W consumption and produce higher temperatures, which is why when assembling a PC it is important to know the ports from which the heat sink or radiator can cool the core processor. It is as much as the importance of bent pins on the motherboard.

The majority of boards already allow some well-named UPPER and LOWER configurations, where we can adjust the parameters in its range based on temperature, and even we want to know how the board fan or pump Control, whether from 3 pins or PWM

CPU_FAN, a connector for CPU fan

This fan connector was already in the PC, however, it has been updated over time to support PWM and range control. Its name tells us that this is the connector where we should connect the fan to the heat sink for the processor or, if we have an AIO system installed on our PC, to connect the radiator fan. This is because of the CPU temperature measurement system.

Note that when you reach the clock speed, the heat generated by the central processing unit increases and therefore it is important that the system can turn on the AIO radiator or heat sink fan, so that Hot air can be taken out. Get out and keep your CPU cooling system cool, let’s see which one we use. This query is as important as people curious about the best motherboard for Ryzen 9 5900x

CPU_OPT (optional)

Some motherboards have an additional connector from the CPU_FAN, however, they do not have the ability to control the temperature of the CPU, as they later share the voltage. This is somewhat controversial in some models of motherboards, as many BIOS for both connectors allow temperature regulation in the range, especially in the upper range. So it is used to connect AIO fans or radiators that use two fans instead of one.


These are the connectors that are used to connect the rest of the wings distributed throughout the box, and therefore, they are used to connect the upper, rear or front wings. Initially they could only be regulated by voltage, but today they are designed to suit the capabilities of CPU_FAN connectors, but they lack a temperature control system. Since we are going to be able to have many fans on our PC, we will find many of them on any motherboard.


To end with the fan connectors, we have H_AMP, which is designed to power the high power fan, as it can triple the energy of a normal connector. The problem with this is that it does not match the standard PC maintenance, a peripheral used to control the speed of different fans in the PC.

Ports designated for water pumps.

If you have a liquid cooling system, you should know that it requires a water pump to circulate the coolant in a closed circuit. Not all motherboards are designed to have this type of cooling, so you should check to see if they are detailed in their technical features.


As the name suggests, this is where the AIO water block pump should be connected. If we use an air cooling system, we can connect it to a common fan. In fact, it is not much different from fan connectors, however, with one important difference and that is that many motherboards include a system that stops the pump and with it prevents the temperature from rising. Allows for minimal revolutions. . Depending on the motherboard model we have, we can adjust the curves from the BIOS or, on the other hand, to adjust the voltage jump via RPM.


Most modern and advanced motherboards usually have this connector, which can give more power to the water pump. However, care must be taken when using this connector, as it can triple the power and energy supplied, so there may be a reading error and we may burn out the fan on duty. This is because it is a high performance pump for custom liquid cooling.

SATA adapter for fans

Yes, as you read: Use the SATA port to connect multiple fans. We rarely use more than 2 SATA 6Gb / s ports because we don’t usually install many SSDs. Even less so with the advent of M.2 SSDs, which have an assigned slot.

In the end, the utility is the same: power multiple fans with one connector. That way, we can power up to 4 extra fans with just one connector. Of course, this can cause problems when reprogramming later because SATA connections are unusual for these purposes.

HUB to control all fans

The user is usually focused on connecting and running all the fans on the PC, but how are you going to control them? Well, Noctua or Corsair have their own HUBs, which act as a switchboard where all the fans are connected and thus, able to control them all without any hassle.

We believe that if you have different fans of the same brand, such as Corsair, it is highly recommended to buy these HUBs. The American brand stimulates its ecosystem with its HUB, able to harmonize the light of all Corsair fans through HUB.

Additional Material


So if what you are looking for is to build a computer with a highly cooling system that exceeds the capabilities of the classic AIO radiator that allows you, then this is the option you should choose, because Its greater power will allow you to use it. Maintain a more powerful water pump and longer clock speeds.

  1. People who follow your social media accounts and website will become your fans. They are interested in what you have to say. You will reach out to them.
  2. The key is consistency. Do not let it go unattended. The more fans you have the more traffic you will receive. More fans mean more followers. The more followers you have, the more fans you will receive.
  3. Make sure to keep your fans updated with information that is useful to them. Use email campaigns, Facebook posts, or other social media campaigns to keep in touch with your fans.
  4. Finally, make sure to have fun. It’s hard work running a business. No matter how hard you work,


Is it possible to install more fans on my PC?

Yes, it’s possible to install more fans on your PC. But it will depend on the type of PC you have, the size of the fans, and how well you manage to fit them in. The best option is to check with an expert and ask him/her about the maximum fan capacity of your PC, and how much you can install.

What is the maximum Ampere a motherboard fan header delivers?

Most motherboards have one or more fan headers, which are used to control the speed of a motherboard’s fan. These headers deliver anywhere between 10 and 80 Amps, depending on the motherboard model. You should use the appropriate fan header for your motherboard, and ensure that you do not overload it with too much current.

How many fans are supported by a motherboard?

A motherboard can support a maximum of 2 fans. The number of fans supported depends on the motherboard’s specification. You should check the motherboard’s manual to get the correct fan count.

Is there a difference between Case Fans and CPU Coolers?

There is a difference between case fans and CPU coolers. Case fans cool your PC case by blowing air across the exterior. They can be placed in different locations to keep the interior of the case cool. On the other hand, CPU coolers cool the CPU inside your PC. They can be mounted inside the case, attached to the bottom or side, or attached to the front or rear of the case.
