When the computer is turned on, the motherboard fan spins and stops.

The computer starts up normally, but the CPU fan only spins once and stops. What should I do?

First of all, it may be a switch problem, such as a bad contact or something like that. of. We turn off the switch on the back of the computer, or simply unplug it. Will reinsert later. If it doesn't work, it may be that the computer has static electricity, causing adverse reactions.

It is recommended to check the power supply or replace it. The cooling fan will turn on or off based on the computer's own cooling conditions, so this phenomenon is normal and there is no need to worry too much. Reason: The power supply fan stops spinning after turning on it. This is a typical power-on self-protection failure. One is caused by insufficient power supply.

If you don’t believe it, you can install temperature measurement software and corresponding software for fan operating status, and try to run some programs that consume the CPU and graphics card for a long time to see how the fan rotates when the temperature rises. In addition, some BIOS settings can adjust the fan operating status through parameter settings, and you can also control the fan speed through some software.

Method 1: CPU fan power supply failure. Under normal circumstances, the CPU fan is powered by the motherboard, and you can find the power supply interface along the fan cable. If you find that the cable is loose, you can try to reconnect it and plug it firmly into the interface. If the CPU fan returns to normal operation, the problem has been resolved.

How to troubleshoot the problem of the computer not turning on: Step 1: First check whether the external wiring of the computer is connected properly, and re-plug each connection to see if the fault is eliminated.

When the computer motherboard is turned on, the CPU fan continuously spins and stops. What is the reason?

1. The fan operates normally. First, if there is no problem with the computer's heat dissipation, the computer's CPU fan spins for a while and then stops. Yes, and then the cycle repeats, this is normal.

2. The CPU fan and power supply fan only rotated once and then stopped. It is obvious that there is a problem with the power supply. The reasons why the CPU fan spins and stops but cannot be turned on are: CPU failure, memory problem, power supply problem, motherboard problem, and heat dissipation problem.

3. There are many reasons for the fan to spin and stop. It may be a problem with the memory module or the power supply. Below, the editor will introduce to you the solution to the problem of the computer fan spinning and stopping. method.

Which case fan is cheaper?

The single-color fans from Xianma are OK. I have been using the blue ones for more than a year, no problem, low noise.

Because Xianyu is a second-hand transaction, it is definitely cheaper than new ones. Because Xianyu is a second-hand transaction, it is definitely cheaper than new ones. The name of Noctua must be well-known among computer enthusiasts in the computer hardware circle. Noctua is synonymous with top-level air cooling. It is also synonymous with many local tycoon enthusiasts.

There are many big brands of chassis fans, such as TT, Cooler, etc. I use an overclocking three silent fan. It makes very little noise and emits blue light. It looks good. The key is that the price is relatively reasonable. , I bought the 9025 model for 22 yuan. The accessory has four rubber screws, which reduce vibration.

Personally, I think the cheaper one is better. If I were asked to install it, I would definitely choose the first one for 49 yuan. The reason is that it is cheap. According to the price of the second one, I can buy three.

You can take a look at the game Titans Transformers 3+ case. This case comes with 2 fan speed regulators, which can control 2 fan speeds, and has low and HIGH gears. In addition to the fan speed adjustment function, this case also supports the installation of up to 5 fans, 2 at the front, 2 at the top, and 1 at the rear.

If you don’t have a mechanical hard drive, it doesn’t matter if you add it or not; the rear fan is used to quickly remove the heat generated by the CPU and graphics card. It is best to add a high-heating graphics card (at least 4-5 degrees, as much as 10 degrees, The effect is so obvious) Quantity, there are many cases with rear fans, so we need to look carefully when choosing to avoid wasting money.
