Why does it get loud when I turn on my computer fan when it s cold?

This is because the temperature is too low, the activity of the oil is not enough, so you don't use refueling, many people think that the lower the temperature in the case, the better, in fact, it is not, it has a requirement that the fan will rotate at high speed when the computer is just turned on, at this time, if the fan is short of oil, it will be very loud, and the sound will be much smaller after entering the system. After excluding the vibration caused by the fan and the sound caused by objects touching the fan blades, the most likely thing is caused by the lack of oil, the refueling method is very simple, first remove the fan from the seat (nonsense), and then see if the back of the fan (a few in the front) is glued with a round plastic sheet, generally sticker.

Peel it off, you will see the motor bearing of the fan, when the oil here is too dry the fan will ring, then find some sewing machine oil or car oil, don't be too sticky, the idea is to drop a drop or two of oil into the bearing cavity, see the oil soaked in the bearing on it (the fan must be kept level), be careful not to let the oil spread to the surface of the fan, otherwise it will affect the viscosity of the plastic sheet, at this time, apply some glue around the oil hole to stick the plastic sheet back and air dry for a while, after drying, install the fan back, then turn on the machine, Is it much quieter?

There are generally three fans in the case: CPU, graphics card and power supply, the first two are easier to get, and the power supply fan is more troublesome because it is necessary to disassemble the power supply. You can listen to which fan is making the sound before doing it, or simply deal with it all together, so as not to toss again and again in the future.

My notebook is like this, when the weather is cold, the fan has been ringing, the hot day has not sounded, I am not satisfied for a while, I personally think that other reasons may be the problem of notebook design, some notebooks detect the CPU temperature by comparing the CPU and the outside environment temperature, if the cup temperature high pressure environment and critical temperature will drive the fan to work. Anyway, if it's not a hard drive, just care about it, just get used to it.

That's what you say, it's cold, the power supply rings or the CPU fan makes a sound. After a while, there was no sound. Nothing to the machine. After the machine warms up, there is no sound.

My computer will too, generally ringing for a while is a problem with the power fan, if it keeps ringing, it is a hard drive broken. If it doesn't affect the luck, it should be fine, I've been using it like this for half a year.

I suspect it's not the sound of the fan, it's the hard drive! I have this problem right now, and I can't help it

The main purpose of the fan is to help the computer dissipate heat and prevent the computer from getting too hot and damaging other parts, causing the computer to malfunction. Generally speaking, the computer will automatically start when the fan is running, but it will not make noise, so people usually do not feel the existence of the computer fan. However, some people find that their computer fan runs very loudly, and the normal use of the computer is affected by the fact that the fan is too loud.

The computer fan is very loud to eliminate:

1. The fan has been used for a long time, the lubricating oil in the fan is solidified, and a large amount of dust is stained on the fan page, which makes the fan difficult to run and produces noise. Playing large-scale games requires large system resources, CPU, graphics card and other hardware acceleration to run normally, CPU, graphics card and other hardware to accelerate the operation, resulting in the CPU, graphics card temperature rise, the system will automatically increase the speed of the fan, due to the fast speed of the fan, the fan noise will also be large.

Open the case, remove the power supply, CPU, and graphics card fan (note that the CPU and graphics card should not remove the heat sink, if you remove it, apply silicone grease glue when you put it on again), remove dust, remove the plastic oil seal, put a little antifreeze lubricating oil or sewing machine oil on the roller, seal it, and then put it on as it is; If the fan is badly worn or broken, replace it with a new one.

Second, the hard disk has been used for a long time, the reading disk will make a loud sound, listen to whether the sound of the hard disk is abnormal, yes, repair the hard disk, or replace it with a new one.

3. Whether the chassis and motherboard are loose and tighten the screws; Sort out all the cables in the case and plug them in tightly.

Fourth, cover the case, listen again, what is the sound, press the case with your hand, if it doesn't sound, it is your case that is too thin or deformed.

Fifth, listen again, what else is loud, and eliminate the symptoms.

The computer fan sound conference has a certain impact on the CPU, but it is not very large.

There are a number of reasons why a computer fan suddenly becomes louder, and here are the possible causes and ways to solve the imitation date:

High temperature: When the temperature of the CPU or other hardware is abnormally high, the computer fan may automatically increase the air speed to cool down the heat. You can use monitoring software such as hwmonitor, speedfan, etc. to see if the hardware temperature is too high, if so, try to remove dust and debris from your computer's radiator, or replace it with a more efficient radiator.

Damaged fans: Computer fans may malfunction due to prolonged use or other reasons. If the blades, bearings, or motor of a computer fan are damaged, the sound may become unusually loud. At this point, it is recommended to replace the computer fan.

Busy applications: Some applications require large amounts of computing resources, which can cause heavy load on the CPU and other hardware. When your computer is under stress, the fan may speed up.

You can use Task Manager to see how much computing resources are being used by applications, close unnecessary programs, or rebase your computer from starting up.

Stuck programs: Some programs may be abnormal or stuck, causing the CPU and other hardware to be at full load for a long time, and the fan operation to be accelerated. Try closing the program that is already stuck or restarting your computer.

It is important to note that a noisy computer fan may be a problem with the computer hardware, so make sure to back up important data and operate cautiously to avoid further damage before adjusting the fan or other hardware. If you are unsure about the cause of the problem and how to proceed, it is advisable to seek professional help.

Here's why a computer fan suddenly goes loud:

1. There are too many computer running programs, the power is increased, the fan speed is accelerated, and the sound of the friend line becomes louder. Don't run too many programs at once.

2. The computer has too much dust, which causes the fan to become louder. Computer dust needs to be cleaned up.

3. The fan lacks oil, resulting in excessive fan sound. The fan needs to be lubricated or replaced with a new one.

4. The fan in the case is loose, and the fan resonance causes the sound to be too loud. The fan inside the case needs to be tightened.
