Why is the computer turned on louder than before

The loudness is most likely a fan issue.

Due to the long period of computer use, there will be a lot of dust on the fan.

Causing the fan to rotate and produce noise.

On the one hand, the cold weather causes the fan lubricating oil to solidify.

Once the machine is turned on for a while, the lubricating oil melts and the sound will naturally decrease.

The fan here refers to the CPU, power supply, or graphics card, etc.!

The reason for the climate, the sound gradually became smaller after turning on, mainly because the weather became colder, and the fan would make a sound when it was turned on suddenly, the solution:

2. Put the computer in a room with a constant temperature, trust me, no problem!

It's cold, the lubricating oil solidifies at the beginning, and the computer runs for a while. A lot of computers have been like this lately, nothing.

The weather is cold, and the fan lube is solidified.

The speaker is the normal sound on the computer.

The boot is louder than before. There are only two places to speak:

1 CPU fan. If you use it for more than 1 year, it is almost easy to replace.

2 In about 2 years, the fan on the power supply will be replaced. Only these two places spoke. Check it out. You can't go wrong.

Because the fan lubricating oil will solidify when the weather is cold, you can wipe it with your hands, in fact, it doesn't matter, don't care.

Well, the answer upstairs is basically accurate, the new machine generally does not have such a problem, after a period of time, when the weather is cold, it is obvious, you can't bear it, you can change the fan.

If you've been using the console for a while, the CPU fan and the power supply fan are all likely to be louder than before, because the dust is inside!

The lubricating oil of the weather cooling fan solidifies, ignore it, and it is good to be hot.

1.This situation is generally cold weather, resulting in the CPU fan hinge or the oil in the ball frozen, or the power supply fan fan hinge or the ball oil frozen, so that the computer boot sound is particularly loud, generally after the computer runs for a period of time, the computer heats up, the oil melts, and the sound will be normal. This usually happens in winter.

2.If the above statement is excluded, it may be because there is too much dust in the computer, and there is dirt on the fan, which increases the fan resistance, so that the fan cannot operate normally, and the computer sound is particularly loud.

3.There is a problem with one of the fans on your computer, including the power supply fan. It must be that the start-up sound is loud, and it will be good slowly, because the fan bearing is out of oil, and the gap between the bearing and the outer sleeve is very tight when it is just turned on, resulting in a very loud sound, and after rotating for a period of time, the sound will be small due to the increase in the gap between thermal expansion and cold contraction.

The solution is to open the chassis and find the loud fan to add some oil to the bearing, but it won't take long, and the second is to replace it with a new fan.
