A simple way to eliminate computer noise

Good and clean computer equipment makes noise during operation, but it is so insignificant that it resembles a breath of wind. The same cannot be said for PCs and laptops that need to be cleaned, lubricated or repaired. Noise should not distract the user during his work. Therefore, you need to know what causes it and how to quickly fix the problem.
There are three main causes of computer noise:
• pollution;
• wear of the main parts;
• grease production in one of the coolers.
It is difficult for a person who is not a computer professional to determine the true cause of the problem. Of course, if there is time and desire, it is best to contact a service center. But in this article I want to tell a way that helped me eliminate annoying noise before the arrival of the computer master.
I want to note right away that this is not a panacea and over time the noise will return. This is a temporary measure that will help facilitate the existence of the user until the arrival of a service center employee.
Step 1. Initially, we need to listen to the computer and establish a noise source. Many details can make a noise. My noise provoked the cooler of the power supply. This is how it looks.
You can also see that the cooler is dusty and needs to be cleaned, but, alas, it is better for a person who has never opened the power supply to remove dirt or complete grease on their own.
Step 2. We cannot completely eliminate the dirt that has accumulated in the fan, without disassembling the power supply, we cannot. But you can lubricate the computer. To do this, you need: a syringe (two), engine oil and a dry sponge.
I want to clarify right away: choose a syringe with a small needle, and you can use only oil for sewing and household machines as a lubricant. The ideal computer grease is, of course, thermal grease. It is thick, does not spread and maintains the working state of all PC parts for a long time. But in this case, you can do without it.
Step 3. Go directly to the remote lubrication. We collect a little engine oil into the syringe.
Now back to our cooler. The fan axis is slightly visible behind the iron mesh. It is covered with a golden sticker. You need to carefully pierce the sticker with a needle in several places and introduce the oil.
Step 4. We remove the remaining oil remaining on the surface with a dry sponge. That's all.
And finally, I want to say that such manipulations are always associated with risk. So think a few times before using my advice.
