Is it important?

Most of us know that electronic devices produce a lot of heat when they are in use. It is because of the resistance offered, but this is not what we will discuss today.

So, when the electronic gadgets and CPU are used for a long time, they generate much heat. If the temperature keeps on increasing and a halt is not kept to it, it will surpass the threshold temperature and lead to either shutting down the computer or burning down the computer.

That’s when the cha fan plays their role. The computer fans will pull cool air from the outside and suck it in. It helps in reducing the temperature to a great extent.

How to connect cha fan to Motherboard?

This fan’s wire is usually four holed at one end, while the other end of the wire is connected to the fan. The 4-pin side must be connected to your central processing unit (CPU’s) motherboard or the Power supply unit. The power supply unit (PSU) is inside the CPU.

If you wish to attach this fan to the motherboard, or you do not have a PSU, then read the following steps:

  • Even if your fan’s wire is three pinned, it still can enter in the pin, and leave the first end of the pin vacant.
  • The temperature of the fans which are attached to the motherboard can be altered.

How to connect cha fan to Power supply unit?

Your fans can take power from a PSU directly. This should be done only when you wish your fan needs to be operated at the highest speed every time. Once attached to this unit, you won’t be able to change the rpm (rotation per minute) value, which is the speed of the cha fan.

You will need a Molex cable to connect your fan to the PSU. One end of the Molex cable should be attached to PSU while the other end to the cha fan.
