100 bounty, high temperature of the computer host, problems with installing case fans

Well, there will be no high temperature in the computer this way.

However, it is important to note that when the fan is blowing on the case, it should never be directly on the fan of the CPU and graphics card. The fan inside the case is very green on hot days, and it is easy to blow off the fan blades (the outer fan and the case fan are reversed), so be sure to find a place with a tailwind. Blow diagonally into the chassis.

But try not to get too strong in the wind.

It is a good method, the principle of heat dissipation is actually that the heat energy is transmitted through the medium of air, simply put, air is equivalent to a conductor, you use an electric fan to speed up the flow of air. This way, the heat energy can be dissipated a little faster. Do you think that when you usually dry your clothes, your clothes dry quickly when it is windy, so don't worry about what you said, landlord, do it boldly!

It is best not to have a fan in the middle of the case, because it will affect the original air flow direction (also called turbulence) of the graphics card and CPU fan, which is not conducive to heat dissipation; Changing to a better radiator works better than adding a fan.

The fan on the back of the case is fine.

The fan tied in the middle won't work.

The air ducts between the CPU graphics cards are messed up.

It is best to place it in the hard drive of the case from the outside in.

Insert failed: You look at the diagram below.

Landlord classmates, how do you feel that your method treats the symptoms but not the root cause (personal opinion)!

The high temperature is still fundamentally solved, and the boot time is shorter. Don't turn 24 hours to 18 hours. If the conditions do not allow, make a small basin of water next to it, the cooling effect is good.

It is not clear whether the 12cm case fan is powered by the motherboard or an external power supply.

But if you have the money, install an air conditioner.

1. Ensure indoor air circulation, and control the indoor temperature in time if the indoor temperature is too high.

2. Clean up the dust of the chassis and sort out the connecting cables in the chassis to ensure the hardware heat dissipation and the smooth air in and out of the chassis.

3. Improve the heat dissipation of CPU and graphics card. Turn off the power, remove the fan on the CPU and graphics card, remove the heat sink, remove the dust, apply silicone grease, and then put it on as it is; Dust the fan, uncover 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.

4. Open one or both sides of the chassis and use an electric fan to cool down, which should keep the host away from people to prevent radiation. Or buy another CPU or power supply fan, add it to the appropriate position in the case, pay attention to the direction when installing, and use it to exhaust air to the outside of the case to cool down, which requires closing the box boards on both sides of the case.

If it's just that the temperature inside the chassis is high, it should be related to the surrounding environment, and it is recommended to lower the surrounding temperature first.

It is recommended to remove the dust first, and then add a case fan, it will work.

This is not a fan issue, nor is it a problem with the motherboard's BIOS settings.

Do you want to figure out why the desktop is ringing when it turns on? But then it's normal?

Reason: First of all, most of them must be because the boot motherboard BIOS has not turned on the temperature control at the same time, so the boot will definitely sound, the reason is that the maximum speed of the fan is running, if it doesn't sound, it's really strange (the main motherboard does not have an alarm sound, these are OK.) ）。

Secondly, I think the fan of your computer should be an old-fashioned original fan or a fan with a speed higher than 2200+ rpm (fans like the Cooler Master and Overclocking 3 that I bought are all high-angle, low-speed heat dissipation, so it's normal if it doesn't sound.) ), so there is no temperature control detected when the boot is running at full speed = ringing.

One is that the movement oil of your fan may have been lost, and the second is that the boot sound is very loud because the computer has not fully entered the intelligent management of the fan speed, and when the program intervenes, the fan speed will be controlled by the program, so the sound will disappear.

Add some oil to the shaft of the motor. Don't say you won't.
