High score bounty Emergency help with CPU fan problems

Are there also fans that are incompatible?

This problem is easy to occur when the temperature is low in winter, and it is likely to ring for a while when the machine is turned on. The solution, of course, is to paint, oil, and replace the new three, if you are not afraid of trouble, the first two are both economical and practical. You can use a small brush or a large oil brush to blow while brushing (it is best to have a "leather tiger" for blowing soot, or you can use a hair dryer to hit the cold air gear, or even use a pump to install a "gas needle" for playing basketball); To apply oil, uncover the circular covering film in the middle of the fan, let the shaft be exposed, and drip a little high-grade lubricating oil (do not use cooking oil, cooking oil will be "sticky" after a long time, affecting the operation of the fan), and then cover the film.

Sometimes not all of them are ringing, how can you tell which fan is ringing? You can take a chopstick, turn on the case, turn on the power, put one end of the chopsticks on the board with a fan, and the other end on the face, and feel a significant vibration. After brushing and oiling, the problem could not be solved, so it had to be replaced with a new one.

It's the quality of the fan. When the blades of the fan are not of the same weight, the high-speed rotation will make a loud noise. It is estimated that the CPU you buy is not the original package, it is an imitation package or a loose chip, and the fan is not the original AMD.

At the same time, please check whether the power cord in the case is bundled, if not, it will make a strange sound if it touches the fan.

Finally, AMD's fans are already loud.

Reason 1: The fan needs to be oiled.

2: The power supply is that the screws on the square box in the host are not tightened.

3: The weather is cold, which takes a certain amount of time to make the oil in the fan lubricated, and there is no noise when you turn it on after shutting down, because the fan has been rotating for a certain time, and the oil in it is not very solidified. Isn't it colder in your place?

Maybe the oil in the new fan has evaporated? What about the dryness inside? It's not impossible. It is recommended that you remove it yourself or find someone else to reap it and oil it.

It's a normal situation, it should be intelligent fan control, when it is just turned on, because the CPU is working, the fan starts to force refrigeration, the speed increases, the noise is larger, after running for a while, the CPU temperature stabilizes, and the fan speed automatically decreases (the fan will automatically stop if the heat dissipation is better), and the noise is reduced at this time.

See if the Ross of your motherboard is tight, according to your configuration, the CPU can get a dual-core.

If it can be used normally, it doesn't matter much.,Anyway, the machine is just matched.,When the time comes, it's not good to take it to the dealer to change it.,According to what you said, it won't be a fan problem.。

Contains bearings, the king of noise.

It is estimated that the new fan spindle you replace also contains bearings, and replacing the ball bearings will solve the problem.

Open the case and push the fan blades by hand.

Change the fan, and the fan is attached to the heatsink, and then it will be snapped.

The quality of the fan is recommended to change to a good one, pay attention not to deceive JS

There is no good or fan to be oiled.

It is recommended to buy ball bearings.

Power supply 300w will not be a little smaller, I am 350w, ,

Oh, you made a mistake with the CPU line, you find the CPU fan on the motherboard and plug in your CPU cable, that's where the CPU power supply, and you can adjust the number of revolutions of the CPU according to the temperature, you should be plugged in now to supply power to other fans, generally the fan plug in the case, you should be able to see it when you open the side cover of the case, take a closer look at the place where your current CPU fan is plugged in to see if there is the word CPU fan, if not, you are plugged in the wrong place, find the CPU It's OK to plug it in.

Good luck to you and your CPU fans!!

This situation is mostly a fan problem, I have also encountered it, just change the fan. If it is the so-called original radiator, it is recommended to replace the radiator completely, and the overclocking three Red Sea standard version is good, side-blowing, dozens of yuan, and the heat dissipation effect is good.

It's obviously a fan problem, you can try a different fan.

Or, it is possible that the motherboard sets CPU fan control, which means that when the CPU temperature is not high, the fan will rotate slowly, and the temperature will be high. Because the CPU temperature is definitely not high when you turn it on, the fan becomes low rev and it is low above the threshold, so it will go wrong. If you can change the BIOS, you can set it to Performance mode, which means that the fan maintains a high speed to improve CPU performance.

But the disadvantage is that it is relatively noisy.

Maybe your current setting is quiet mode, quiet mode.

Let's learn how to set up the BIOS. Useful for you, I also read the manual to learn.

The rotation speed and temperature control of the CPU fan are done by IO, you can find a place to repair the computer and replace an IO chip.

It's a fan problem, it's the motherboard can't detect the CPU fan, so change a heatsink.

It's best to take it to a repair shop and give him a test.

1 Change the CPU cooler.

2 Apply some silicone grease between the CPU and the heatsink.

The fan plug is not in good contact! Or the motherboard power supply system is not connected! You can try plugging the motherboard's power cord back into the fan!

The fan interface has a standard CPU fan> and then turn it on to see! The speed of a general fan is not so prone to problems! Unless there is a problem with the quality of the fan itself!

1. It should not be universal, because the lock of AMD K8 and P4 478 is different. P4 doesn't heat up so much that you don't need a heat pipe at all.

2. I just upgraded from P4, a few days ago I bought a Cooler Master Defender TIB, which is a copper stamen, brand new only 25 yuan, 2500 rpm, 1700 rpm after adding a deceleration line. Not bad. The room temperature is 15 degrees, the standby is 31 degrees, and the full load is 47 degrees.

The temperature is about 10 degrees lower than the previous one.

3. Heat dissipation is not only to change the radiator, the key is the chassis heat dissipation air duct! I used a 38-degree chassis, and I bought 2 8cm ultra-silent fans with three overclocks, one in the power supply and one in the case. Now the noise is basically inaudible, and the chassis is generally cool.

What's wrong with the CPU fan, please elaborate.

Your question is unclear and doesn't explain the problem!

If it is a problem of slow CPU fan speed, the first possibility is that the fan speed is controlled by a temperature control chip, and the CPU temperature is not high, so the speed is slow! The second possibility is that the fan is aging!

If the fan is aging, it's best to change the radiator as a whole! It's not expensive!
