The newly bought chassis is very loud, first aid

It is recommended that you tighten the screws of the chassis enclosure and place the chassis in a flat place to avoid vibration and noise. Sounds such as fans inside the case are normal, and you're a new machine, so there's no way there's too much dust to get louder.

Whether your hardware volume switch is too large,And whether the volume in the operating system is adjusted well,If it doesn't work, please check whether the interface is connected,If you can't change the speaker, it's your previous no,If it doesn't work, it's a problem with the computer,Change a sound card。

This is caused by resonance. Please tighten the screws and so on on for the accessories inside. There is a high probability that it is caused by the CPU fan. You double-check there.

I just bought it not long ago, of course, I asked the boss to check.

If it's inconvenient, you can disassemble the chassis to see if it's ringing.

Is it a power supply fan or a hard drive or a CPU fan.

If it is not the fault of the fitting itself, it is speculated that it may be caused by the vibration caused by the screw not being tightened somewhere.

It is impossible for a desktop computer to have no sound, and the loud sound can only be the function of those fans, which cannot be solved, but if the sound is too loud, changing the fan may reduce the noise.

1. The CPU fan is loud.

2. The chassis is poor, the plate is thin, and the sound insulation is not good.

It is impossible to have no sound, the so-called silent power supply is just a little quieter, and it is quieter at home, of course, it seems louder.

Eliminate power supply fan noise.

Power supply fan noise is generally divided into rotational noise and vibration noise. Rotational noise is generally caused by a lack of lubrication in the fan bearings. The solution is to apply a few drops of sewing oil to the fan bearing.

Vibration noise is generally caused by unbalanced fan blades, loose blades on the shaft, and excessive bearing clearance. If it is the accumulation of dirt on individual leaves, it can be removed in time; If the fan blades are missing, asymmetrical, or the bearing clearance is too large, it is best to replace the power supply fan with a new one.

Eliminate CPU fan noise.

The bearings and blades of the CPU fan are the most likely places to cause noise, and after long-term use, the bearings of the fan may have too much friction due to lack of oil, resulting in large noise, so you can add some sewing oil to the fan shaft. The specific manipulation of Qi Sun Zuo is to carefully uncover the label on the fan shaft, add oil and then cover it. If the quality of the fan blades is not very good, after a period of rotation, the fan blades may be deformed due to heating, touch the inner wall, and make noise.

The solution is to take the blade and gently scrape the scratch a few times to increase the distance between the fan blade and the inner wall to avoid friction between the two.

Cancel hard drive noise.

The noise of the hard disk may come from its own vibration, and at this time, it is not just as simple as making annoying noise, but also involves the safety of the hard disk. Because the vibration caused by improper installation may damage the hard disk, the hard disk installed in the water fiber chain must be parallel to the chassis, and the vertically mounted hard disk must be perpendicular to the bottom surface of the chassis and cannot be skewed.

You first check whether it is the power supply fan or the CPU fan or the graphics card fan, if it is confirmed, it is best to change the fan, if the fan has abnormal noise, it must be the shaft derailment, and the dripping oil is only a temporary sound of small sound, it is best to replace the fan, the heat sink does not need to be replaced, and the single fan is not high, 25-45 yuan.

The main causes of chassis noise are loose installation of accessories inside the case, aging fans, and hard drives.

Solution: 1] The fitting installation is loose. Check whether there are any problems such as loose accessories, screws falling off, or power cables, hard disk floppy drive cables, etc.

If it is found to be loose, please tighten the screws and ensure that there are no scattered screws in the chassis (easy to cause short circuit); If the fan is in contact with the power supply, hard disk floppy drive, etc., fix the power supply, hard disk floppy drive and other cables with a fixed cable to ensure that there is no contact with the fan;

2] Fan aging. There are fans such as CPUs, graphics cards, power supplies, etc. inside the case. Long-term operation of the fan will naturally deteriorate, resulting in noise.

The fan can be replaced separately or the fan and fan heatsink can be replaced together; If the warranty period has passed, you can remove the power supply from the chassis first, then open the power supply case and replace the internal power supply fan. Note that the fan size of the CPU and graphics card is basically the same, and the fan size of the old power supply and the new power supply is slightly different.

3] Hard drive issues. Some brands of hard drives, the normal sound is very loud. If the drive makes a very irregular sound (i.e., it is noticeably different from the sound of reading and writing data), or if there is a noticeable sound of the head rubbing against the disk pads, the drive may be damaged or is about to be damaged.

At this time, the most important thing is to copy the useful files in the hard drive, and then send the hard drive to the supplier or joint warranty manufacturer for inspection. If you send a hard drive for inspection, check whether there are confidential or important files in the hard drive as much as possible (sometimes this is not possible), and strive for the security of corporate information.

Note: Hard drives are one of the most fragile accessories, so it's important to keep regular backups of your data or files (servers, other hard drives, tapes, burn disks, etc.).

Generally, the host has not been cleaned for a long time, and there is too much dust inside, if there are tools to disassemble the host by yourself, brush it with a brush, and then blow it with a blower.
