What are the internal interfaces of a computer motherboard? Recommended introduction to the internal interfaces of a computer motherboard
php editor Xiaoxin introduces to you the internal interfaces of the computer motherboard. The motherboard is one of the core components of the computer. There are many types of internal interfaces, including CPU slots, memory slots, expansion card slots, SATA interfaces, and USB interfaces. wait. Different interfaces have different functions, which affect computer performance and scalability. When choosing a computer motherboard, understanding the characteristics of each interface can better meet your needs. Next, we will introduce you to the various contents of the internal interface of the computer motherboard in detail, hoping to be helpful to you.
In the process of assembling the computer, although the installation process is simple, we often encounter problems in the wiring. Often the installation user mistakenly plugs the power supply line of the CPU radiator into the SYS_FAN, although the fan can Turn it on, but there may be an F1 error "CPU Fan Error" when booting, which also prevents the CPU radiator from intelligently adjusting the speed. Let's share the common knowledge about the CPU_FAN, SYS_FAN, CHA_FAN, and CPU_OPT interfaces on the computer motherboard.
Popular knowledge on the CPU_FAN, SYS_FAN, CHA_FAN, and CPU_OPT interfaces on the computer motherboard
1, CPU_FAN
CPU_FAN is the CPU cooling Special interface for the fan, 12V working voltage, 4PIN (pin), the 4-pin fan has a PWM intelligent speed adjustment function, which can intelligently control the fan speed according to the load and temperature changes. Compared with 3 pins, the line with more than 4 pins is the speed adjustment line. The 3-pin fan does not have PWM adjustment capability, but it can detect the fan speed. The air-cooling radiator fan or water-cooling radiator fan is connected to the CPU_FAN, and the 4-pin PWM intelligent temperature control can avoid the problem of excessive noise.
CPU_FAN
2. SYS_FAN
SYS_FAN is also called "system cooling fan socket", 4PIN (pin), general It is connected to the chassis fan. Some installed users may add chassis fans in order to have better heat dissipation conditions inside the chassis, or to build air ducts, and they will all be connected to the SYS_FAN interface. If the chassis fan is 3-pin, it is It can be plugged in and used, but there is one less speed adjustment cable. In addition, some motherboards have CHA_FAN, which is a chassis fan, but you can also use it to connect other 12v fans.
SYS_FAN
If there is only one CHA_FAN or SYS_FAN on the motherboard, and there are multiple chassis fans, how do you connect them? These fans are all 4 Yes, if you want to achieve speed adjustment or divine light synchronization, you can just buy a fan hub (FAN HUB).
3. CPU_OPT, aio_pump
CPU_OPT and aio pump are special interfaces for water-cooling pumps. If you have split water cooling, they are generally connected to the water-cooling pump.
aio_pump
There are also some biased ones, chip_fan belongs to the north bridge fan, and PWR_FAN belongs to the power supply fan, which are generally not used.

When we assemble the computer, although the installation process is simple, we often encounter problems in the wiring. Often, users mistakenly plug the power supply line of the CPU radiator into the SYS_FAN. Although the fan can rotate, it may not work when the computer is turned on. There will be an F1 error "CPUFanError", which also causes the CPU cooler to be unable to adjust the speed intelligently. Let's share the common knowledge about the CPU_FAN, SYS_FAN, CHA_FAN, and CPU_OPT interfaces on the computer motherboard. Popular science on the CPU_FAN, SYS_FAN, CHA_FAN, and CPU_OPT interfaces on the computer motherboard 1. CPU_FANCPU_FAN is a dedicated interface for the CPU radiator and works at 12V

Introduction to PHP interface and how it is defined. PHP is an open source scripting language widely used in Web development. It is flexible, simple, and powerful. In PHP, an interface is a tool that defines common methods between multiple classes, achieving polymorphism and making code more flexible and reusable. This article will introduce the concept of PHP interfaces and how to define them, and provide specific code examples to demonstrate their usage. 1. PHP interface concept Interface plays an important role in object-oriented programming, defining the class application
Solution to NotImplementedError()
Mar 01, 2024 pm 03:10 PM
The reason for the error is in python. The reason why NotImplementedError() is thrown in Tornado may be because an abstract method or interface is not implemented. These methods or interfaces are declared in the parent class but not implemented in the child class. Subclasses need to implement these methods or interfaces to work properly. How to solve this problem is to implement the abstract method or interface declared by the parent class in the child class. If you are using a class to inherit from another class and you see this error, you should implement all the abstract methods declared in the parent class in the child class. If you are using an interface and you see this error, you should implement all methods declared in the interface in the class that implements the interface. If you are not sure which

Inner class implementation of interfaces and abstract classes in Java
Apr 30, 2024 pm 02:03 PM
Java allows inner classes to be defined within interfaces and abstract classes, providing flexibility for code reuse and modularization. Inner classes in interfaces can implement specific functions, while inner classes in abstract classes can define general functions, and subclasses provide concrete implementations.
Application of interfaces and abstract classes in design patterns in Java
May 01, 2024 pm 06:33 PM
Interfaces and abstract classes are used in design patterns for decoupling and extensibility. Interfaces define method signatures, abstract classes provide partial implementation, and subclasses must implement unimplemented methods. In the strategy pattern, the interface is used to define the algorithm, and the abstract class or concrete class provides the implementation, allowing dynamic switching of algorithms. In the observer pattern, interfaces are used to define observer behavior, and abstract or concrete classes are used to subscribe and publish notifications. In the adapter pattern, interfaces are used to adapt existing classes. Abstract classes or concrete classes can implement compatible interfaces, allowing interaction with original code.
Java interfaces and abstract classes: revealing the inner connection between them
Mar 04, 2024 am 09:34 AM
Interface Interface defines abstract methods and constants in Java. The methods in the interface are not implemented, but are provided by the class that implements the interface. The interface defines a contract that requires the implementation class to provide specified method implementations. Declare the interface: publicinterfaceExampleInterface{voiddoSomething();intgetSomething();} Abstract class An abstract class is a class that cannot be instantiated. It contains a mixture of abstract and non-abstract methods. Similar to interfaces, abstract methods in abstract classes are implemented by subclasses. However, abstract classes can also contain concrete methods, which provide default implementations. Declare abstract class: publicabstractcl
