Restore computer fans, You must monitor restore computer, computer cooling system closely, but may have serious problems later. Overheating your computer may stop responding, fail, may be damaged not only the graphics card, motherboard chipsets, but the CPU.
Yes, some processors have temperature sensors and emergency computer power in case of overheating. But, in practice, it is not always 100% working. Either a new processor, at least $ 100, good graphics card are also cheaper there.
All computers are equipped with forced air cooling, i.e. in most cases the fan (cooler). Although there are rare examples of modern supercomputers, which are equipped with water cooled.
So, let’s look at how to retrieve fan?
First you need to select any of the noise of the fan, because they are in the system unit may be several. There is one simple way to do this-and take turns to slow the fans and press gently with your hand or a piece of cloth. If noise is gone-it means.
It is known that when the fan is gradual deterioration of his influence, and dust builds up and the wind impeller hair, feathers, etc after a while he starts making unpleasant, and other sounds, and the speed of getting off, and may even stop altogether. Faster fail fans with sleeves. Fans with bearings are more durable, but also more expensive.
To avoid problems it is necessary to periodically, at least once in six months, is cleaning and inspection of computer preventive. Especially it is necessary to do, if Nestle of animals (cats, dogs, etc.). It’s a down fans, often stop, cause the computer from overheating.
To restore the fan in the first place must be cleaned, vacuumed, and remove dust, lint, and other foreign objects. Sometimes it helps and it works fine. Otherwise, you must change one new fan. Or, if worn bearings yet heavily, trying to restore it. To do this, it must be removed from the computer and dismantling.
To remove the impeller, the back of fan shooting round sticker with the name of the manufacturer, and underneath you will see a small depression, the end of the impeller hub. Small screwdriver, extract the circus repair washer, in the shape of a horseshoe, with the hub and remove the impeller. Now you have to remove the old grease from the shaft and fan bearings frozen, more comprehensive, if necessary, clean the impeller of dust and dirt.
The impeller blades can be washed under a stream of warm water and SOAP, and then dry it, you can erase with alcohol or vodka. Pro-clean cloth, dry best for gasoline or alcohol may damage the winding insulation solutions. The impeller hub and wash with gasoline or alcohol.
Now we must all pull in reverse order and properly lubricated. Lubricates axis with a thin layer of liquid, lubricating oil or oil for sewing machines and paste it in the body of the fan impeller, bearings must be lubricated, but not so much that the grease has been published. After Assembly and lubrication of fan is necessary to close access to the bearings or duct tape, so do not let dust.
Each fan is ready to work for several more months at least six. Now it can be scanned and returned to the computer. As for the bearings of the fan, and then restore them is not much different from what is described above. The only difference is that you need to use the grease lalmhaml, for example CIATIM, ythol-24, or replace them with new ones.
By the way, if the fan stands in a convenient location, and grease, and it cannot be removed, remove the sticker and low on the axis in the middle of a single drop of oil light machine gun, and this is quite enough, and then scroll down a bit for him to go deep into the lubricants. Of course, the system at the same time it is necessary to expand the fan so that was horizontally and grease leak deep.
It happens that the CPU cooler is very dirty and needs to be removed for cleaning. It is not hard to do, there is a catch. If you do this, it is necessary to repack that thermal paste (white, but the content of silver, and silver). Put the back cooler carefully, without extra effort not to break anything.
And a few lines about lubricants. In bearings, as is the use of liquid lubricants lubricants only: silicon oil or engine oil. Oil viscosity is determined depending on the wear of sliding bearings. If you wear a small fan beeps only (dry lubricant)-then use oil 10-15W, medium viscosity, or silicon. If the fan noise-and these are the signs of a great generation and application of 20-25W oil, high viscosity.
I also want to say that because of the noise of the PC may not be a fan, but also computer parts guaranteed bad: hard drive, motherboard, system cover, etc., in such cases, we need only to tighten the screws and the problem is resolved.
