What is the interface of cha fan? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Cha_fan is the socket of the chassis fan, and cha is the abbreviation of chassis, which means chassis.

The chassis cooling fan interface generally has 3 PIN interface and 4 PIN interface, of which 3 PIN interface is the fan power supply interface on the motherboard. If the motherboard has this interface position, the fan power cord can be plugged directly into the motherboard. If the chassis fan only has a 4 PIN interface, then it can only be connected to the power supply.

In addition, for some mainstream fans, it is generally equipped with both 3 PIN and 4 PIN interfaces to meet compatibility. In this case, you can choose to connect the motherboard or power supply, depending on where there is a location.

If the fan has a 3 PIN interface and the motherboard has an idle 3 PIN fan interface, it is recommended to connect the motherboard first, so many motherboard fan interfaces have the function of intelligent speed limit, which can adjust the voltage according to the internal temperature of the chassis and realize the function of intelligently limiting the speed of the fan.

Considerations for chassis fan installation:

Generally, the chassis fan is installed in the front of the chassis, inhaling cold air from the front to blow over the motherboard, and finally discharged by the power supply fan to form convection. It is best to consider the direction of air flow, the best solution is to install a fan before and after each, diagonally distributed, and then the heat dissipation effect of the whole chassis is very good. The front fan of the chassis blows to the inside and the rear fan to the outside.

Convection CPU, graphics card, hard disk, optical drive, north bridge, south bridge and other chips on the board heat the air in the chassis all the time. If these hot air are not discharged out of the box, the heat dissipation of various components will be seriously affected and the service life of the computer will be affected. The measured results show that the temperature in the box with fan is 5 / 10 ℃ lower than that without fan, which can obviously improve the working environment of the accessories and electrical components in the box.

In general, there are always two places for fans in the chassis, the front one is generally in the hard disk bracket, and the rear one is generally under the power supply and above the keyboard port. The principle of air flow should be followed when installing chassis fans. If the installed fan goes in and out, the air flow inside the chassis is regular from front to back.
