2 Pin Fan to 4 Pin Motherboard | Can You Make It Work?
A cooling device with 2 exposed electrical terminals or pins is known as 2 pin fan. The 4 pins of a 4-pin motherboard connector are utilized to power the fan from the motherboard. A 4-pin CPU connector is included on some motherboards and is used to supply controlled voltage to the CPU fan.
A 3-pin to 4-pin converter can be used if your computer doesn’t have a 4-pin CPU connector. Either a 3-pin or 4-pin connector can be used to connect a 2 fan to the motherboard. There are three wires on a 3-pin connector and four on a 4-pin connector. Check before buying a fan to see if it comes with both connectors.

What Does 2 Pin Fan Mean?
A male 4-pin Molex connector is typically found at the end of a 2-pin fan’s wires, but only two pins are used. This connects directly to the PSU’s power supply connector. It always runs at full speed if you do it that way.
What Does 4 Pin Connector Mean?
The 4-pin connector is a 12V power supply cable that is used with Intel Pentium 4 and later CPU motherboards. The connector is now a common power connector for Intel and AMD motherboards.
Things You Need to Connect 2 Pin Fan to 4 Pin Motherboard
There are a few things you’ll need to connect a 2-pin fan to a 4-pin motherboard.
- A 2-pin fan
- A 4-pin motherboard header
- A 3-pin fan
- A soldering iron
- Solder
- Wire cutters
Things You Need to Keep in Mind
When connecting a 2-pin fan to a 4-pin motherboard, there are a few things to keep in mind.
- To begin, determine which of the four pins on the motherboard is the ground pin.
- Then, connect the two wires from the fan to the motherboard’s ground pin and one of the other pins.
- Last but not least, make sure the fan is connected to a power source.
The Procedure of Setting 2 Pin Fan to 4 Pin Motherboard
It’s not as challenging as it may seem to connect a 2-pin fan to a 4-pin motherboard. It’s a quick and easy process.
This is how to connect a 2 fan to a 4 motherboard.
- The first step is to locate the four pins that will be used to power the fan on the motherboard. These pins are commonly called “PWR FAN”, “CPU FAN”, “CHA FAN1”, and “CHA FAN2” and are normally positioned near the CPU socket.
- Cut the wires on the 2-pin fan as close as possible to the fan. Only the black and red wires will be used.
- Look for the 2 fan’s wires. Black and red are most likely to be used.
- Match the color of the wire on the fan to the motherboard connector’s color.
- The wire should be pushed into the connector until it snaps into position.
Different Ways of Connection
A 2-pin fan can be connected to a 4-pin motherboard in a few different ways. You can use a fan splitter to connect the fan to one of the motherboard’s 4-pin headers and then split the signal into two 2-pin connectors. This is the simplest method, but it can also be the most costly.
Using a 4-pin to 2-pin adaptor is another option. This will allow you to connect the fan to the motherboard‘s 4-pin header and then use the adapter.
Features of 4 Pin Motherboard Connector
The 4-pin connector is larger and more rectangular than the 2-pin connector. This 4-pin connector is seen on greater power supplies, such as those used by graphics cards. Some power supply has both connectors, while others only have the 4-pin.
A black wire, a yellow wire, a red wire, and a blue wire make up the 4-pin connector. The black wire serves as a ground wire, while the yellow wire serves as a 12V power line, the red wire serves as a 5V power wire, and the blue wire serves as a 3.3V power wire.
What Are the Benefits of a 2-Pin Fan?
The 2-pin fan’s key advantage is that it can be controlled by the motherboard, allowing the fan’s speed to be modified according to the system’s requirements. This provides for improved cooling and noise reduction. Another benefit of employing a 2-pin fan is that it allows users additional alternatives for fan installation.
Last Words
A 2-pin fan connector is a type of power supply connector that connects a fan to a motherboard. A 4-pin motherboard connector is a connector that connects a motherboard to a 4-pin power supply. The conclusion of this article is that a 2-pin fan may be connected to a 4-pin motherboard, however, an adapter is recommended.
