How to clean and lubricate the fans of the computer system unit

Is your desktop computer loud? Is it buzzing, making noise, or maybe even growling? This is a clear sign that the coolers of the system unit of your computer need to be cleaned and lubricated.

This article shows how and what to lubricate and clean coolers, the most simplified method of lubricating and cleaning a computer, internal system fan, accessible to a simple, unprepared user, and not requiring special tools and knowledge.

We will clean the fans and the system unit with brushes and a vacuum cleaner, but how to lubricate the coolers of the computer system unit? This question is asked by many PC users. It is easy to do this, knowing very little about the “composition” of the system unit.

For lubrication, we need oil for lubrication. Motor oil is most commonly used, but household oil can also be used to lubricate sewing machines. If you choose a motor, it is better to take a synthetic, but a mineral of good quality also copes with its direct responsibilities. Do not mix mineral oil with synthetic. Consistency can also be used in different ways. Liquid oil is easier to inject into the motor with a syringe, but dries faster … And viscous will have to be smeared with a match (or other similar object) and the blades will spin harder from such oil. Graphite-based lubricants will not work – they can cause a short circuit in electrical circuits. Well, we have decided on the lubricants, let’s go further on the list.

We also need a screwdriver, vacuum cleaner and brush (or cotton swab) in order to thoroughly clean the coolers and their blades from dust. Well, here we have everything we need. So let’s get started. First, we need to open the case of the system unit.

Depending on the model of your computer case, you may need a suitable screwdriver. And some models of cases even open without the use of any improvised tools. After opening, vacuum all the space inside the system unit so that everything is clean before work. Next, unscrew the cooler from the back wall of the system unit. Disconnect the fan power from the motherboard.

We take out the fan from the sys. block. We remove the processor fan together with the radiator, separate it from one another and carefully clean the fan and radiator with a vacuum cleaner and a cotton swab dipped in an alcohol solution.

It is desirable to achieve the highest possible cleanliness of the surface of the ribs for better cooling of the processor. The impeller and all nearby parts must also be cleaned. And so we pulled out the rear cooler and radiator with a fan. If you have a supply of thermal paste on hand, use alcohol to clean the contact surfaces of the radiator and the CPU itself from the old paste, let them dry thoroughly and apply a thin layer of the new thermal paste. If there is no fresh paste, just spread the old (not recommended) like plasticine with a thin uniform layer without lumps. Well done with the radiator. Now to the fans. It is necessary to unstick the sticker on the central panel of the cooler, but not completely. we need a stalemate.

Next, open the plug on the fan motor.

Inside, fill in a little lubricating oil. We drip on the axis 2-3 drops (of your choice) of oil with a match, pipette or syringe.

Then close the lid back.

Next, we remove all traces of oil from the surface where the plug is stuck, let dry. Carefully glue the hole for lubrication (you can even use tape).

The tightness of the newly lubricated assembly depends on the thoroughness of this moment, namely, if the oil will leak out when the temperature rises, which will not be the best for your computer. Stick the stick in place.

This is so that the oil does not leak. After lubrication, insert the coolers in place, connect them. We close the system unit, check the tightness of the fit of both covers, connect the wires and enjoy the silence of the work.

Coolers will work like new. Over time, the grease from heating will evaporate from the sleeve, and it will be necessary to repeat this operation again.

P.S. If the lubrication of the fans did not help or for a very short time, they continue to make noise and make obviously unhealthy sounds, which means coolers require either a more serious repair or replacement. In service centers, coolers are dismantled, the lock washer is removed from the axle, the impeller is removed and the peeled magnet is pulled out, greased with glue and inserted into its place.
