How to connect extra fans to motherboard

How to connect extra fans to motherboard

When your processor starts to overheat, it threatens to frequently “hang” from system processes. How to solve the problem? Of course, you can buy a new cooler and install it instead of the old one. But here’s the rub: If you have an old computer, it’s not that easy to find exactly your type of CPU cooler. And it is that a new cooler, even if it fits your processor, does not always have enough power (even if it is new and a higher number of revolutions per minute is indicated on the label). Also, if the user does not live in the city, but somewhere on the outskirts, then it may not be impossible for him to buy a new cooler. Yes, that’s the way it is! However, this is not a reason to hang your nose – there is always a way out! We look. Let’s start with the old power supply that failed. You, of course, replace it with a new one and throw the old, broken one in the trash. So: don’t rush to do this, because the old power supply can serve you well. More precisely, not a block, but it’s cooler.

And now in more detail. 

Then! If you disassemble the power supply and take a closer look at the cooler, you will see exactly how it is connected to the power supply board: there is a complete wiring harness, and there are also two separate thin wires – red and black. Now carefully remove the cooler (unscrew the four fixing bolts), and also carefully unsolder these two wires – red and black. Now the cooler is in your hands. But this is half the battle – now it remains to connect it correctly. Remove the wall from the system unit and look at its power supply (working of course). Each power supply has two types of connectors: flat input and round input. Are you interested in the round ones? In turn, round connectors are divided into “father” and “mother”. You are interested in the “mother” entry. A colored wire is connected to each “socket” on the round connector. 

You are only interested in two: black and yellow.

 You connect the black wire from the cooler to the “jack” with the black wire, and the red wire to the “jack” with the yellow wire (that’s right). Secure the wires with a piece of electrical tape. Turn on the computer; the cooler should spin immediately. If everything is in order, it remains to fix the cooler. Depending on the purpose, you can solve this problem yourself. For example, if you need to connect a cooler to the processor, you can do it with a common copper cable. It is enough to pass the cable under the points of adhesion of the radiator to the processor platform, pass the cooler holes through the cable “antennas” (there are only four of them), and simply twist the cable several turns, after pressing the cooler against the radiator. In short, you will immediately understand everything – just look at the cooler and the four holes. By the way, with the video card, the same algorithm

Everything is extremely simple if only show a little ingenuity and care. Good luck! 5 Honest Online Earning Services Summer comes all year. Everyone gets hot, including computers. Only, unlike a person, it is permissible to install additional cooling on a computer, in particular, to install one or more coolers. They provide an additional intake of cold air into the system unit and the result is burned air. Will need Computer, correct size cooler, basic computer assembly skills 


 1. First you need to determine where and which fans need to be installed. 

To do this, remove the case covers and inspect the case for ventilation holes. Most often, they are located on the front and back panels of the case. Measure the distance between two adjacent holes for fixing the cooler (they are located on a “square”, you need to measure its side). With the measurement results, go to the store and buy the necessary fan.

 2.Three-pin fan connector on the motherboard 

Please pay attention if there is a free three-pin fan connector on the motherboard.You can find out where it is located in the instructions for the motherboard, in the diagram, as usual, it is called “System Fan”. Depending on the board model, these connectors can be from one to five. If there is no free connector, you must purchase a fan with direct connection to the power supply or equipped with a suitable adapter.

 3. Rotation of the blades and the air flow

On the side surface of the cooler there is a mark indicating the direction of rotation of the blades and the air flow. Coolers are installed on the front panel “to blow” and on the back – “to blow”. Attach the cooler into place from inside the box and secure it with the self-tapping screws it comes with. Occasionally silicone “pins” are included instead of screws, making the fastening procedure even easier and preventing the transfer of cooler vibrations to the case.

4. Connect the cooler cable to the power connector

 Connect the cooler cable to the power connector (on the motherboard or casually to the power supply). Power on the computer and check to see if the new coolers are spinning and if so, in which direction. To do this, bring them a thin strip of paper, it should not be climbed on a working fan with your fingers. Carefully close and secure the case covers. Throughout the year, the computing power of the devices grows at a rapid rate, at the same time, the power consumption also increases. And when there is not enough power supply with standard connectors on the motherboard, they resort to using additional conductors along a separate power supply line.
