The CPU fan will spin very loudly, how many revolutions per second does the CPU fan normally?

If there is no sound after that, then your computer is a good computer!

If the sound is still so loud after it gets bigger, it's hard to say!

Is the chassis shaky?

If the case is shaky, it means that the fan blades are broken, and you need to replace the fan!

If you don't shake, it may be that there is no lubricant in the bearing, add some lubricant!

It is also possible that the silicone may have dried up or failed!

Take the fan out, tear off the sticker on the outside of the shaft, drop two drops of lubricating oil into it, and then paste the sticker to ensure that there is no noise.

Wipe the old silicone between the CPU and the heat sink, and then apply the new silicone, and the heat dissipation will be fast.

Be careful + careful when operating!

Identification done! Good luck!

good luck！

That's the same sound, isn't it?

It's about 2-3 seconds, isn't it?

That's normal!

Yours is a great machine!

That's normal when loading! If only I had a machine like this!

The fan is too dirty and there is still a lack of oil, take it down and clean it up and add some oil.

I have time to change a fan blade shaft A few dollars My computer has also had such a problem It is as bad as a piece of paper It would be good to change it If you don't have time, you have to take it down and clean it up and refuel The oil filling hole is generally under the label Sewing machine oil can be But it will ring in the future.

Is it new? Let's take a look at the speed of the fan first. Oil the fan and see if it works.

It depends on the design of the fan itself.

The high-speed fan has more than 6000 rpm.

Low-speed fan 900 rpm.

The speed is not important, the key is that the temperature is not exceeded.

Maybe your CPU is constantly running under high load, making the temperature very high, and the CPU fan works automatically according to the temperature reflected by the CPU sensor. If your CPU supports inverter, it is recommended to enable this co-operation in BIOSZ. Also, if you are using Vista, set the power management mode to energy saving mode, and if you are using XP, set the power mode to "Battery Max" or "Power Minimum".

In this way, the CPU will also automatically reduce the frequency under the system configuration, reduce power consumption, and the temperature will drop, and the fan will naturally become well-behaved!

The speed of the fan will be louder when the speed is high, the machine of 6520s can press the F10 key to enter the BIOS at the boot for a setting (connect the power supply fan and keep turning), if you feel that the fan is loud, then you can turn this off.

The fan power supply is not connected, or the fan motor is damaged, or the fan is stuck by dust, or the fan power supply is not in good contact, or the power connector of the motherboard is connected to the fan, go buy a new fan and try it.

Try to run a game, when the CPU temperature exceeds 70 degrees, see if the fan is turning, if it does, the fan is normal.

It's burned out, just replace it.

It's certainly not a run-in problem.

CPU fans are only getting louder and louder, not quieter.

There will be no shortage of oil when you just bought it.

The only solution is to adjust the speed or change the fan.

See if your motherboard supports auto speed regulation. If the motherboard CPU socket is four-pin, yes.

The software can be set up.

If not, you can only change the silent fan.

If you are sure that it is the sound of the CPU fan, if you are not sure, stop the fan with your hand and listen, if there is still a sound, it means that the quality of the style is not good.

Is there vibration or some part of the resonance if the screws are not tightened, and the lubricating oil for household appliances.

CPU speed is different, fan speed is not the same, in CMOS there is a special detection of CPU temperature and fan speed display and control, more accurate, and with the CPU temperature rise speed, there is also CPU temperature and fan speed measurement and control software on the system desktop, if you are interested, you may wish to try it, you can get it through search, software also has, for example: eversst, etc., you can directly get the CPU temperature, fan speed, CPU voltage, etc.

Let me help you refer to it! I've had this problem too, but it was caused by my carelessness! The CPU almost burned out!

I cleaned up the dust and oiled the fan When I installed it, I forgot to connect the interface between the fan and the motherboard, hehe, the consequences can be imagined, the crash does not stop the blue screen, and finally I reflect it relatively quickly Shut down and recheck!

I'll help you with your questions, see for yourself if it helps!

First of all, the elimination method - the fan basically does not have the problem of lack of oil for 6 months, or it is original! However, individual counterfeit and shoddy products are not excluded! It also depends on the working hours of your computer fan!

There is no big problem with the power interface between the motherboard and the fan, whether the fan turns or not, it has nothing to do with the computer configuration, it is recommended that you remove the fan, dispose of the dust, and then take off the sticker on the fan, and put some oil on the rotating shaft inside, preferably white oil, sewing machine oil, or cylinder oil.

Can it solve your problem?

If you eliminate it, leave the graphics card, memory, and CPU on the motherboard, and unplug everything else, and the display should be able to light up.

If you still can't get up, the fault is on the graphics card, memory, and CPU.

Personally, I feel that the motherboard is very likely.

The others are not lit.,Let's see if your corresponding cable is connected.,The display doesn't respond.,Look at the power supply of the display、Is the data cable connected?。 If it is connected, remove the graphics card, erase the gold finger with an eraser, and then install it and try it out.
