How to connect fans to motherboard

When it comes to computer technology, there are a lot of small parts which need to work together perfectly. Cooling air is circulated around the components by CPU fans, which are an essential part of the processor.

Whether you need to replace the previous fan or your computer is overheating, putting in a new one can help cool and even calm it down.

First Method: Buy a fan.

1. Verify the cabinet’s dimensions.

80mm and 120mm are the most common sizes of desktop fans, but you may need a fan in a different size, like 60mm or 140mm. For those who aren’t sure, you can remove the existing one and take it to a local hardware store where you can buy a new one with the same size and ask again for size or a way of measuring it yourself.

2. You’ll notice that 120 mm fans are the norm in modern cases.

As an alternative to simply trying to replace the burned fan, you should check to see if the new fan will be able to circulate air to the necessary components. You are out of our reach.

This piece of writing. Video cards and processors, for example, require their own dedicated cooling fans to draw air over the exchangers or heat sinks connected to each individual device. ۔

In the cabinet, take a look.

Place fans in strategic locations. As a general rule, there is a fan on each side of each tower. Bear in mind that the maximum number of supporters that can be installed in each case model varies.

3. Choose the larger fans if you can, if at all possible.

If your case can accommodate a variety of fan sizes, the larger ones are almost always the best option. Fans with 120 mm diameters are noticeably quieter and more efficient than those with smaller diameters.

4. Make a comparison of different fan models.

If you want to compare fans, read the product descriptions and customer reviews. Take advantage of a quieter setting that’s also more reliable. In general, fans are inexpensive, and buying four at once can save you a lot of money. A few notable manufacturers include:

The master is cool.

  • Invariably cool
  • Intensely frigid
  • Corsair
  • Thermaltake

5. LED and basic fan options are available.

Fans with Light bulbs can be used if you want to give your case a little flair. Please remember that they’ll brighten up one’s cabinets in a variety of colors, but they’re a little more pricey.

6. It is important to choose a fan that has the correct power plug for your system.

Open your PC case and check the power cords coming out of it and see what kind of power cable your fan (fan) should have if you plan to connect it to the power supply. ۔ Molex, three-pin, and four-pin connectors are the most common.

To be safe, some power supplies have different types of plugs that allow you to buy any kind of fan you want. Connecting the fan to your motherboard will allow you to adjust

its speed (unless you have a special feature on your computer that allows you to control the speed without the motherboard). Allow) Fans can be connected to motherboards using 3-pin or 4-pin connectors.

Method 2: Opening the cabinet

1. Disconnect the computer from the wall.

This is a straightforward step.

2. Disconnect your computer from the power source. 

For a minimum of ten seconds, keep the power button pressed.

3. Removing the side panel is necessary for this step.

You will have to delete the side panel in front of the motherboard in order to access the interior of your computer. Remove the grip from the rest of your computer system by removing the side panels. Side panels may protrude in some cases.

The motherboard’s other side panel is typically on the left.

In addition to the patches mentioned in the panel configurations, there are a variety of other configurations, including ones that have reverse leeches and those that require you to press them to unlock the panel.

4. Clean up any static that has built up.

When working on a computer, always put your feet on the floor first. Components can be severely damaged by electrostatic discharge. An anti-static forearm strap or a metal faucet can be used.

When working on the computer, keep the band on the ground and don’t download frequently so that you can start releasing the static that you’ve accumulated.

5. Ventilate the entire space. 

Fans can be managed to install in any of the cabinet’s vents. Depending on the case model, you can find people just on the back, front, sides, or even the top of your computer.

6. Locate the motherboard’s electrical connectors. 

They can be strewn across the floor or just one pair. System and CHA FAN# fan connectors can be identified by their numbers. Check your motherboard’s manual if you’re having trouble locating connectors.

Using the Molex adapter, if you have more fans than plugs, you can connect them all.

Method 3 Installation of fans

Method 3: Installation of fans

  • Comprehend how an efficient air-conditioning system functions. Keep in mind that the most efficient way to slow down the CPU is to not blow a small amount of air on the elements for the fan’s operation. The most efficient way to cool a computer is to move the air around the entire system.
  • Verify the fan. One of the fans’ functions is to circulate air, as indicated by an arrow just on top of the supporter cover. This tells you where the wind is coming from the fan. If you don’t see any printed arrows, look for the fan method’s label. In most cases, the air enters from the side with the label.
  • Create a wind tunnel by arranging the wings in this manner.
  • Exhaust fan and air injection are used to create a wind tunnel. In most cases, an exhaust fan should be installed over the case instead of an injection fan. All cupboard slots and tiny holes will sketch cool air into the cabinet when a void effect occurs.
  • A fan at the rear of your computer’s power supply called the rear blows air out the back (exhaust). Make sure the air is pushed out of the case by putting in a few more fans on the backside.
  • The front end Front-load your computer with an air-sucking injector fan. Depending on the case, you may be able to add a second fan to the hard drive harbor.
  • Set one’s side fans to circulate air from the sides. Support for side fans is common.
  • In order to remove the heat from the very top of the case, you’ll want to use the upper fan’s exhaust setting, but please remember that this will also produce more feed air.

Installed fan. 

Using the four included screws, affix the fan firmly to the wall. To avoid vibration, make sure the fan is properly adjusted. If you need to eliminate or consider replacing the fan in the future, be careful not to overtighten the screws.

Do not let any of your electrical wiring get tangled up in any of your ceiling fan’s blades. Use cable ties if necessary to keep them in place.

While screwing, if you find it difficult to keep the fan in place, use a few strips of tape to help keep it in place. Keep the tape from adhering to any parts or circuits. “


Turn the fans on. Connect the fans to the motherboard’s power ports. If you have too many fans or the connections are too short, use a Molex adapter to connect them directly to the power supply.

As a result, if you connect the fans directly to the power source, you won’t be able to alter the fan speed in the BIOS. It’s time to close the cabinet. Before testing the fans, make sure the case is closed.

You won’t get sufficient cooling if you leave the casing or fan open, which is why they’re designed that way. The cooling efficiency of open cabinets is significantly lower than that of closed cabinets.
