Does the computer power supply fan face the label inward?

Computer power supply fan orientation Many people will encounter a problem when assembling a computer: Should the computer power supply fan face the inside or outside of the label? This article will delve into this issue, introduce the impact of different fan orientations on system cooling and performance, and guide you to make the right choice under different circumstances to ensure that the computer runs stably and efficiently. Read on for this guide to learn the best way to orient your computer's power supply fan to prevent overheating and potential hardware damage.

Is the computer power supply fan facing inwards towards the label?

Computer power supply fans exhaust air outwards, mainly to remove the heat inside the chassis, so as to achieve the effect of ventilation and heat dissipation, so generally power supply fans are exhausting

Upper power tower What is the correct direction of the fan?

Tower cpu fan direction

1. According to the general tower radiator design, there will only be a fan on one side, and according to the air duct design of the chassis, we should talk about tower type The radiator fan faces the memory side;

2. The air duct design of the tower radiator is as follows. The lower temperature air is driven by the cooling fan and passes through the fins from right to left to take away the heat above. , the air temperature rises and is discharged; the air with higher temperature is discharged out of the chassis through the fan on the back of the chassis, thus completing the heat dissipation process.

How long is the lifespan of an assembled computer power supply?

If we talk about the life span after use, this is not necessarily true. It may break in one year, or it may not break in ten years. But if we talk about performance life, the longest is estimated to be 5 years. After 5 years, even the current mid-to-high-end configurations may even have web pages and QQ stuck by then

In fact, many computers are being operated The system was eliminated. The new operating system has high hardware requirements, and old computers are too slow to run the new operating system. Just be eliminated. This is the trend and law, and it is also the need of software and hardware manufacturers and dealers.

Change computer power supply to fan?

Cut off the original 2-pin wire, separate the positive and negative terminals and wrap them with electrical tape. Or do other processing, just don't short circuit anyway.

It is recommended to go to JD.com, Newegg, or Computer City to buy a Kyushu Fengshen one. Of course, other brands are also good. It is best to have a large 4-pin interface, which is the power port of an IDE hard drive.

For 12CM fans, we recommend Kyushu Fengshen XFAN 120 (the rotation speed should not be lower than 1300), and for 8CM fans, we recommend Kyushu Fengshen XFAN80 (the rotation speed should not be lower than 1800). About 20 yuan.

You can also buy one with a 3-pin interface, but you need to have an extra 3PIN interface on the motherboard or buy a large 4-to-3PIN interface. I recommend the AVC one, which is very cheap and easy to use.

Never buy an unlicensed second-hand one, it may be worse than the original one.

After installing the new fan with screws, lead the fan's power cord from the gap between the upper and lower housings of the power supply (it's okay if the wire is caught in the middle, that wire is relatively tough) to the outside of the power supply.

You can also lead the fan power cord out of the black wire hole where the PC power supply output wires come out.

Connect the fan power cable to the large 4-pin D-type connector of the PC power supply, or the 3-pin connector on the motherboard. Remember to connect it, otherwise the fan will not spin and the power supply will overheat and burn out! ! !

Everything is OK! I have used this method to modify several power supplies, and the results are very good.

Replace the computer power fan?

Replace the computer power fan?

11. How to remove the power supply fan? Before replacing the power supply, you must first understand these issues: fan size and fan interface. These two points can be viewed internally by disassembling the power supply. Disassembling the computer power supply is very simple. Just use a Phillips screwdriver to remove the power supply from the chassis. When disassembling, be sure to cut off the power supply and disconnect all the connections between the power supply and the hardware.

2 Remove the fixing screws first. It should be noted that most of the current power supply fans are designed to blow upward or sideways. If it blows upward, the fan is fixed in the upper cover of the power supply. When disassembling, be sure to pay attention. , there is a power cord in the fan connected to the internal PCB. When disassembling, be careful to open the cover. You need to disconnect the power cord, and then open the upper cover, as shown in the figure below.

3 Pay attention to disconnecting the fan power supply interface. Note: One of the four screws of the power supply has a fragile sticker with a date on it. Disassembling the power supply means that the power supply will lose warranty service, so disassembling the power supply Before using the power supply, first find out whether the power supply has passed the warranty period. If it is within the warranty period, do you want to solve it through after-sales maintenance?

4 (1) Unplug the power cord of the power supply fan from the PCB power supply motherboard slot. You need to use a little force here; (2) Use a Phillips screwdriver to remove the power supply fan fixing screw, and then Remove the damaged fan; (3) Fix the new power supply fan in the power supply, then install the fixing screws, and insert the power cord into the power socket on the PCB board inside the power supply. Be careful not to insert it backwards.

5 Next, don’t rush to install the power supply into the chassis. First test whether the power supply fan can rotate.

Does the computer power supply not require a fan?

Do not use the power supply fan, otherwise it will restart after a while or burn out the power supply. In addition, do not remove the iron plate on one side of the computer. This will affect the formation of air ducts inside the computer and affect cooling. At the same time, because the side plate is removed, the noise inside the chassis will increase. It is recommended to add lubricating oil to the fan or simply replace the fan.

How many fans do I need to buy to assemble a computer?

Normally, it depends on the configuration of the computer. The more fans, the better. Too many fans will cause noise and dust over time, and the computer's power consumption will increase. Computers with ordinary configurations (note: computers with integrated graphics cards and computers with entry-level graphics cards and automatic small fans) do not dissipate much heat. In addition to the built-in fan of the power supply, an ordinary CPU fan will suffice.

High-end computer: The chassis must be well equipped, and at least 2 fans must be installed on the chassis. If the CPU is water-cooled with a fan, the fans must be installed on the chassis. There is also a heat exhaust fan, which removes the heat generated by other computer hardware. High-end graphics cards can also be retrofitted with water-cooled radiators, and the fan must be installed on the chassis, depending on user needs!

Assembling the computer power supply is not on?

It may be a power problem! It's very simple. Unplug everything plugged into the motherboard from the power supply first, then use a paper clip on the 20+4 pin end to connect the green wire to any black wire. If the power supply fan is spinning Then the power supply is good and can be ruled out.

After confirming that the power supply is good, connect the motherboard power supply and CPU power supply. If the independent graphics needs power supply, also connect it. However, if there is integrated graphics or nuclear graphics, it is recommended to unplug the independent graphics first (click When it lights up, it shows independently on top). Then unplug the hard drive indicator light, power indicator light, and restart button (leave only the power-on cable), and then turn on the computer. If it cannot be turned on, it means that the connection between the indicator lights, the reset button, and the power-on button is wrong. !

How to choose the power supply for assembling a computer?

1. Power, first look at the power of your power supply hardware, and look at the rated power of your graphics card and CPU.

The simplest algorithm is to add the graphics card and CPU, plus 200W. If the power is not enough, no matter how good the brand is, it will pale in comparison.

Excessive performance will feel like a waste.

2. Check the size of the chassis to see if it can fit. If it can’t fit, replace the power supply and chassis, which is a bit troublesome!

3. For wires, you can choose full modules, straight-out cables, or semi-modules. Full-module assembly is simpler.

4. Power supply efficiency and quality. Nowadays, power supplies have various solutions, such as DC-DC, EMI filters, capacitors, etc.

Solid capacitors in power supplies are better, and single-channel 12V current is better. A friend who doesn't install the computer often can't understand many parameters. Simply buy a good power supply with confidence. Look at the brand. Taiwanese and American Corsair products are not very cost-effective. In fact, they are a bit exaggerated. Domestic power supplies include Great Wall, Huntkey, Cooler, etc. to choose from.

My friends around me use Great Wall power supplies the most. Domestic power supplies from Great Wall are used in civilian, military, aerospace, supercomputers, servers, etc., which shows that they are of excellent quality. A 400W bronze power supply for home and office use is enough. Games, etc. require more than 500W, and both bronze and gold medals are acceptable. The efficiency and quality of gold medals will be better than bronze medals.

How to choose the power supply for assembling a computer?

The power supply for assembling the computer should be a national standard brand product with a power that is at least 1/3 greater. If the power consumption of the host is 350 watts, then a nominal power supply of 450 watts or more should be used
