How To Connect Fans To Motherboard? Simple & Quick

When it comes to cooling your computer, adding additional fans is a great way to help keep things running smoothly. Most computer cases today have ample space for additional fans, so you won’t have to worry about overheating. However, it’s important to make sure that the fans you add are mounted correctly and placed in the right spot, as otherwise, they could actually end up making your system run hotter. 

This can be a tricky process, but it’s definitely doable. In this blog post, we’ll walk you through the process how to connect fans to motherboard step-by-step. So read on to learn more!

Find Out The Right Fan For Your Motherboard:

If you’re looking for the right fan for your motherboard, there are a few things to keep in mind. First, make sure you choose the correct size for your case. Secondly, be aware that cheap fans may not last very long and may produce more noise.

Try to opt for something well-known or that has received good reviews. Thirdly, four-wire fans are easier to control than three-wire fans. And finally, larger fans are better in terms of noise reduction. So don’t be afraid to get a little extra geeky and compare options to find the perfect fit for your needs.

What are some common fan connectors?

There are three common types of motherboard fan connectors: three-pin, four-pin, and Molex. Three-pin connectors are the most basic and are typically used for smaller fans, such as those found in CPU coolers. Four-pin connectors are for larger fans, such as those found in case fans. Molex connectors are for even larger fans, such as those found in industrial applications.

Three Pin Fan Connector:

The three-pin fan connector is the standard for PC case fans and CPU fans. It’s a simple connector that has three pins: ground, +12V, and sense. The +12V pin supplies power to the fan, and the sense pin is used to monitor the speed of the fan.

 It has three pins arranged in a triangle and is used to connect the fan to the motherboard. The three-pin fan connector is also known as the TX3 connector. The three-pin fan connector is used on almost all motherboard models. It is the most common type of fan connector and is compatible with almost all fan types. The three-pin fan connector is easy to use and is very reliable.

Four Pin Fan Connector:

The 4-pin motherboard fan connector is used to connect a CPU or chassis fan to the motherboard. It is typically found near the CPU socket on the motherboard.

The 4-pin fan connector is usually colored black, white, or blue, and will have four pins arranged in two rows. The first two pins are for power, while the last two pins are for ground. To connect a 4-pin fan to the motherboard, align pin 1 of the connector with pin 1 of the header on the motherboard. 

Molex connectors:

The Molex motherboard fan connector is a four-pin power connector used to connect a fan to a motherboard. The Molex connector is a female connector with four pins arranged in two rows two. The Molex connector is typically used to connect case fans and CPU fans. The fan connector can also be used to connect other devices, such as LED strips.

This connector is typically used for CPU or system fans. The motherboard fan connector is also known as a PWM connector.

The four pins on the connector are labeled as follows:

  • pin 1: ground
  • pin 2: +12V
  • pin 3: a tachometer
  • pin 4: PWM control

To connect a fan to the motherboard, you will need to connect the ground and +12V pins to the appropriate header on the motherboard.

How Do I Connect Fans to My Motherboard?

There are a few things you need to do in order to connect your fans to your motherboard. Here are the steps that you need to follow!

1. Research and buy the best motherboard for your computer. You can find this information in your computer’s user manual or by researching online.

2. Find the fan connector port on the motherboard. It will likely be labeled “CPU fan” or “chassis fan.”

3. Plug the fan cable into the correct port. If the fan has a 4-pin connector, make sure to plug it into a 4-pin port.

4. identify the power source for the fans. The vast majority of fans will be powered by either the motherboard or the power supply unit (PSU). If the fan is being powered by the PSU, then it will likely have connected properly.

5. Secure the fan cable to the port with a zip tie or electrical tape. This will prevent the fan from becoming disconnected.

How Can I Tell If My Fan Connector is Working?

There are a few ways to tell if your fan connector is working. The first way is to check the voltage at the connector. If the voltage is correct, then the connector is probably working. Another way to tell is to check the amperage draw of the fan. If the fan is drawing the correct amount of current, then the connector is probably working. Finally, you can check the resistance of the fan. If the resistance is within the normal range, then the connector is probably working.
