About the problem that the main engine fan is very loud!! 5

Go buy a bottle of sewing machine oil, and add some points in the middle of the fan to solve the problem.

If you want to change a fan, you have to match it with the CPU, and the fan is not expensive, generally ranging from 10 yuan to 100 yuan.

If it's just a start-up sound, the sound will disappear soon, normal! Mine is the same!

If it is always loud and noisy, it may be too much dust, so take it off and clean it.

After a long time, the fan will also age, usually 2 to 3 months to add some lubricant. It's best to keep the inside of the case clean!

The price of the fan ranges from tens to hundreds, and the power is also different.

Civilians can buy one for a few dozen.

Just buy a fan for 10 yuan, and dozens or hundreds of those include heat sinks, but there is no need to replace the heat sink with the fan sound. There is no need to change the fan if it is noisy, add some better lubricating oil to try it, it really can't be changed, maybe the fan will be saved!!

It's time for your fan to be oiled! I don't know which fan you are talking about, since it is mentioned as "very loud", then let's think it is a power supply fan, remove the power supply after the case is powered off, disassemble the power supply to expose the fan, clean the dust in the power supply with a tool such as skin spray, and then use the oil pot to drop the oil on the fan bearing (a few drops can be), and then dial a few times to make the oil flow evenly, and then you can reinstall it, other fans are treated in the same way, it should be simpler! I recommend you give it a try!

The fan is very loud.

One: How many years has the fan been used?

2: The frequency of use of CUP is high, and whether to use software with high CUP occupancy.

Three: Check whether the silicone is dried.

Four: Check whether there is a lot of dust on the fan.

What fan do you use?

The fan of the 478 is more than 10 dollars.

The 775 fan is generally better in the early 30s.

Try it with some lube.

There are dozens to hundreds of fans to change fans.

The place where the host can make sound is the power supply, CPU, graphics card, these 3 fan sounds, you can replace the graphics card fan with a heat sink, clean the dust of the fan and put some oil on the CPU and power supply fans.

**From $20 --- several hundred.

It's best to change the fan sound, it doesn't take long to refuel, a fan costs a few dollars, but you see which fan it is, there is a CPU on it, there is a graphics card, there is also a power supply, see which one it is, look at the model, go to the computer market to buy one, and replace it.

Power on and off! Wait 3 seconds before it turns on! Restore BISO to factory settings!

The host ringing is not necessarily a fan problem, the landlord can disassemble the chassis, listen to it** ringing, hard disk, optical drive will ring, and then see if the fan will be very.

Dirty, if it's dirty, clean it up with the brush a little, and if it's still loud, it's recommended to change the fan to try.

1 fan is about 30-40 pieces, don't be hacked!!

The sound of the main computer case of the subject computer should be mechanical. You can first check the operation of each cooling fan. Observe the mechanical sound of the fan.

Then, deal with the problem cooling fan.

You can also use shock-absorbing glue to paste it on the chassis seal plate to achieve the effect of shock absorption and noise reduction.

The fan in the host unit is aging. The host includes power supply fans, CPU fans, graphics card fans, and power supply fans. Such issues can clean up the power supply fan dust.

Prepare the oil and toothpicks, unload the power supply from the top of the chassis, then open the housing of the power supply and remove the fan. Find the place where the dust is sniping, use a gentle brush to clean the dirty place, after the cleaning is completed, there will generally be a label on the front of the fan, open the label, and use a toothpick to dip the oil on the bearing under the label. Then glue the label back, restore the power supply, and put it back on.

Note: a. When oiling the bearing, the amount of oil should be appropriate. b. When filling the fan with oil, use special oil or high-quality sewing machine oil, and accelerate the wear of one side of the bearing. Many of today's silent power fans have been rigorously tested to reduce noise, so you can consider replacing the silent power fans.

Generally, the noise of the case is caused by fan resonance, and in most cases, the graphics card is more so

If the fan has an abnormal sound, try to apply some lubricating oil first, if it still rings, change the fan, the fan shaft is not in the center will cause loud noise, this can not be repaired, only replaced.
