Lenovo computer K415 CPU fan ringing loudly, what s going on

The laptop does not have good heat dissipation, the graphics card CPU temperature is high, and the fan rotation noise comes out at high speed.

Buy a quieter fan, don't be too expensive, overclock, three gold, hunger, macro ants (very quiet, basically no sound, lift a car), or Donghai, this fan has a governor.

Method 1: Fix the fan at a speed and adjust it to about 100, so that it is about 2200 rpm, and the sound is not loud.

Method 2: Auto-adjust.

Step 1: When both the motherboard and CPU fan have automatic speed regulation, go to the motherboard COMS to set it.

Step 2: Set the CPUFAN TargetTemp Value to 55 degrees, the CPU Fan Tolerance Value to 10, the CPU Startup Value to 200, and the CPU StopValue to 150, then when the CPU temperature reaches 55 degrees, the fan will run at full speed, and when the temperature is lower than 55, the fan will run at a relative speed of 200, and it will decrease at a linear rate of 10 Drop to a relative velocity of 150 and then run at a speed of 150.

This is because of the serious heating, and if the problem of heating is solved, the fan will not be so loud.

There are several causes of fever:

1.If the heat dissipation port is blocked, you need to open the back case of the notebook, get the blocked heat dissipation port through, and use a cotton swab leather to remove the dust on the fan.

2.It is also possible that the laptop has been in contact with the desktop for too long, if it is not an office, you can buy a desktop cooling fan, remove the fan, and put the heat sink on the laptop where the heat is very hot, which can also help heat dissipation.

3.Sometimes the computer running the program configuration is too high, which will also cause the laptop to heat up, you can press the Ctrlaltdel key to enter the Windows Task Manager, and check if there are any programs that are consuming computer resources.

1.Optical drive, if the optical drive is rotating, the sound is the most obvious, of course, under normal circumstances, there is no disc in it, it will not turn;

2.Hard disk, as long as there is read and write, it must be running all the time, but the sound will not be very loud, especially if it is a solid state drive, it is no longer a rotating structure, it is almost silent; If it's really that loud from the hard disk, I'm afraid the problem is bigger, and the price of data is great;

3.Fan, if it is not a portable and energy-saving design notebook, the fan will continue to rotate, if it is a new machine that is still loud, it is a design problem. But now notebooks are almost all energy-saving designs, especially the energy-saving performance balance of the integrated graphics cards of the current Intel chip product lines is very good, and there will not be too much energy pressure in ordinary use.

3.Third, there are real design issues, such as whether HP died back then. Mistaken cockroach door] notebook DV2000, DV3000, is a design problem that caused the hard disk and graphics card to dissipate too poorly, and finally burned out.
